Main article : Olivia Benson Portrayed by Mariska Hargitay Episodes : `` Payback '' -- present Olivia Benson is a detective in the Manhattan Special Victims Unit, which investigates sex crimes. She is primarily partnered with Elliot Stabler, until he retires after season 12. She is tough, empathetic, and completely dedicated to her job, to the point that she is sometimes seen as having little personal life. Her dedication sometimes wreaks havoc on her emotional state as she empathizes with victims of sexual assault, having been the child of rape and later the victim of sexual assault while undercover in season 9. She has allowed her compassion for victims of abuse to sometimes cloud her professional judgment and impede her ability to remain impartial. Hargitay has received both a Golden Globe and an Emmy Award for her portrayal of Benson. In season 13, Detectives Benson and Tutuola are the senior detectives in the precinct. Throughout the first few episodes of season 13, she struggles to cope with the retirement of Stabler as she is more harsh and argumentative, as seen when she berates ADA Novak for `` losing her nerve '' after Novak said that Benson was `` off. '' Her primary partner from season 13 to 14 has been Nick Amaro, but is also seen working with Tutuola and Detective Amanda Rollins at times. Upon the retirement of Sergeant Munch at the beginning of season 15, Captain Cragen recommends to her that she should take the sergeant 's exam, as she was now his second in command. In the episode, `` Rapist Anonymous '', she makes the announcement that she has passed the exam, officially making her a sergeant. After Cragen 's retirement, she becomes acting commanding officer of SVU until she is subsequently promoted to Lieutenant in season 17 and officially takes command of the unit. At the end of season 15, she became a foster mother to Noah Porter, formally adopting him at the end of season 16. She is taken hostage midway through season 17 ( `` Townhouse Incident '' ), but is rescued unharmed. Shortly thereafter, she begins a relationship with IAB Captain Ed Tucker. Fin Tutuola Fin Tutuola has been portrayed by Ice - T since 2000. Main article : Fin Tutuola Portrayed by Ice - T Episodes : `` Wrong is Right '' -- present Odafin `` Fin '' Tutuola is a sergeant in the Manhattan Special Victims Unit. He was raised in Harlem and he served in the United States Army, where he saw combat in Mogadishu. A former undercover narcotics detective, Tutuola replaced Monique Jeffries after she left the squad in 2000. He transferred out of narcotics after his partner was shot. He initially has a rocky relationship with his colleagues in SVU, especially his partner John Munch and Olivia Benson. He sees the world in black and white, with all criminals equally deserving of prison regardless of extenuating circumstances. He also keeps a tight rein on his emotions, refusing to talk about his problems or to admit that the grisly nature of his work often affects him. He rarely talks about his personal life, not revealing he has a son to his fellow detectives until the sixth season. As the series progresses, he becomes closer with Munch and even saves Benson from being raped while they were both undercover in season 9. However, he also begins clashing more frequently with fellow detective Elliot Stabler. As of the season 8 episode `` Screwed '', he is assigned Chester Lake as his new partner. After Lake kills a suspect, Stabler accuses Tutuola of tipping him off before he is taken into custody and checks his phone records. Tutuola admits he called Lake, but says he did not expect him to run. Stabler quasi-apologizes for not trusting him, but Tutuola dismisses his apology because he believes Stabler will always be the same `` bulldog ''. Afterwards, he requests a transfer from the squad, however the man in charge of transfers is a former colleague of Tutuola 's who holds a grudge against him. Tutuola resolves himself to being `` stuck '' and his captain, Don Cragen, orders him to investigate a case with Stabler, who he calls a `` headcase '' and `` cranky - balls ''. As time has passed, Tutuola has again warmed to Stabler, a point proven in the season 11 episode `` Solitary '', when a suspect throws Stabler off a roof, Tutuola nearly throttles the suspect for attacking his `` friend ''. After Lake 's departure at the end of season 9, Tutuola was again partnered with Sergeant Munch from seasons 10 to 12, sometimes working alone or with Benson and Stabler when Munch was unavailable. Beginning in season 13, Tutuola 's primary partner is Detective Rollins. Amanda Rollins Amanda Rollins has been portrayed by Kelli Giddish since 2011. Main article : Amanda Rollins Portrayed by Kelli Giddish Episodes : `` Scorched Earth '' -- present Amanda Rollins is a detective from Atlanta, Georgia, who moves to New York City to join the Special Victims Unit. Rollins appears to be a detective who is very anxious to do her job, often being told not to get ahead of herself by Detectives Benson and Amaro, and Captain Cragen. She appears to have a good rapport with her partner, Detective Tutuola, compared to his last new partner, Chester Lake. Shortly after transferring to NYC, Rollins deals with a serial rapist case that had a familiar twist for her. Rollins tries to prove to Benson and Amaro that the rapist originated in Atlanta and has come to New York for new prey, almost falling victim to him in an attempt to flush him out, since he took a preference to blonde and athletic women. When Rollins becomes distraught over a case where an actress is raped by one of the men in her life, Rollins asks Benson how she can trust any man after working this job. Benson reassures Rollins and tells her that she trusted her partner. As for Rollins ' personal life, little is mentioned of her off - duty life ( although, being from Atlanta, she is a fan of the Braves, whose schedule she keeps on her refrigerator door ) ; Amanda has mentioned that she has a sister, Kim, who has had psychotic and drug issues. Kim has also suffered repeated abuse by her ex-boyfriend. She says that while she was working in Atlanta, there was an accident that occurred that allowed for her to transfer to the SVU. Amanda also was exposed as a heavy gambler in the episode `` Home Invasions ''. When Cragen discovered her problem, he threatened to take her badge, but decided to help instead -- since he is a recovering alcoholic -- by requiring her to attend Gamblers Anonymous meetings. Rollins ' previously mentioned troubled sister, Kim ( Lindsay Pulsipher ), comes to New York in the season 14 episode, `` Friending Emily '', causing problems for Amanda while she is trying to work a case. Later in the episode `` Deadly Ambition '', Kim returns to New York beaten by her ex-boyfriend Jeff and claiming to be pregnant. When Amanda hears screams from inside her apartment, she finds Kim 's ex-boyfriend attempting to rape Kim, and Amanda shoots and kills the man as he pulls a gun on her. The supposed evidence of Amanda shooting Jeff in cold blood leads to Lt. Tucker arresting Amanda in Captain Cragen 's office. The charges against Amanda are later dropped when Amaro tapes Kim confessing to setting Amanda up for a life insurance policy on Jeff. Before Kim can be arrested, however, she steals everything from Amanda 's apartment and disappears. In the episode `` Poisoned Motive '', Rollins is shot by a sniper in front of the precinct. Her shooting leads back to the daughter of Detective Tutuola 's narcotics partner, who is out for revenge on the NYPD after her father was injured on the job by protecting Tutuola from a bullet. In the season 15 episode, `` Rapist Anonymous '', Rollins is caught in the middle of a case in which her friend from G.A. claims to have been raped. When the alleged rapist is killed, her friend is put on trial and Rollins ' personal life is revealed on the stand. This proves too much for her to handle and she is seen gambling, smoking, and drinking in the final scene. Later in season 15, she frequents an illegal casino ( `` Gambler 's Fallacy '' ) and is exposed as a cop by a 15 - year old waitress whom Rollins and Benson had assisted in an earlier episode. The operators of the illegal casino threaten to out Rollins to Benson, and although Rollins comes clean to Fin, Benson is still outraged. Rollins eventually breaks up an art theft ring with the help of Lt. Declan Murphy, who was undercover as one of the casino operators. In the season 16 episode `` Forgiving Rollins '', it is revealed Rollins was raped by her commanding officer in Atlanta, Deputy Chief Charles Patton ( Harry Hamlin ) in 2010. This comes to light when Patton is in New York for a conference and is accused of rape by one of his APD detectives, Reese Taymor ( Dreama Walker ), at a Manhattan hotel. Rollins is revealed to be pregnant in the two - part season 17 opener when she is interviewing serial killer Dr. Gregory Yates ( Dallas Roberts ). The father is revealed to be Declan Murphy, who came back to New York during Super Bowl weekend 2015 to infiltrate a sex trafficking ring. Rollins undergoes a difficult pregnancy before giving birth to a healthy baby girl, Jesse. Giddish was pregnant in real life and gave birth to a boy in October 2015. Dominick Carisi, Jr. Main article : Dominick Carisi, Jr. Portrayed by Peter Scanavino Episodes : `` Girls Disappeared '' -- present Detective Dominick `` Sonny '' Carisi, Jr. is introduced in the season 16 premiere, `` Girls Disappeared. '' He originally serves as Detective Amaro 's temporary replacement when Amaro is reassigned to Queens. He has brief SVU experience in other boroughs, including Brooklyn, Queens, and Staten Island. Carisi gets off to a rough start with his new colleagues, coming off as blunt and insensitive during his initial meeting with Sergeant Benson and Detective Rollins. In the fifth episode of season 16, it is revealed he has permanently joined the Manhattan SVU team and Scanavino is added to the opening credits. In the same episode, Carisi helps turn one suspect against the other suspect during the investigation of a pornstar 's rape, earning him praise from Benson. Carisi is also a military veteran, having enlisted in the Marines 2 weeks after 9 / 11. Carisi has three sisters, one of whom, Bella, gave birth to a baby girl just before Rollins gives birth to her daughter. He is seen to enjoy time spent with Rollins ' daughter, Jesse, and Benson 's adopted son, Noah. Carisi is a devout Roman Catholic and a graduate of Fordham Law School ; he passed the bar exam at the end of season 17 and considering taking a job with the Brooklyn district attorney 's office, but chose to remain with the NYPD in the wake of the shooting death of Mike Dodds. Elliot Stabler Elliot Stabler was portrayed by Christopher Meloni from 1999 to 2011. Main article : Elliot Stabler Portrayed by Christopher Meloni Episodes : `` Payback '' -- `` Smoked '' Elliot Stabler was a senior detective in Manhattan 's 16th Precinct, also known as the Special Victims Unit, which investigates sex crimes. He is one of the original members of the squad. A former Marine and a dedicated detective, he has a 97 percent closure rate, but his dedication can turn to obsession and cause him to take cases personally. His dedication to the job also makes him the target for several IAB investigations during the course of his 12 - year career at SVU. At the start of the series, he is married with four children. He separates from his wife Kathy during seasons 7 and 8, but they reconcile after she becomes pregnant with their fifth child. Elliot is Catholic, which sometimes complicates the cases he works on, but also helps him form a close friendship with ADA Novak. His partner is Olivia Benson, with whom he generally has a good working relationship, but it is not without tension and friction, especially in seasons 7 and 8 when they are separated as partners for some time. Captain Cragen also makes both detectives speak with psychiatrist Rebecca Hendrix in order to decide whether they can continue working as partners. Dr. Hendrix tells Cragen that he should split them up only if he wants to lose his two best detectives. John Munch John Munch was portrayed by Richard Belzer from 1993 to 2014 ( Homicide : Life on the Streets ). Main article : John Munch Portrayed by Richard Belzer Episodes : `` Payback '' -- `` Wonderland Story '', `` Spring Awakening '', `` Fashionable Crimes ''. John Munch was a detective, and later a Sergeant in the Manhattan Special Victims Unit. A conspiracy theorist and dedicated detective, Munch is first partnered with Brian Cassidy ( Dean Winters ), whom he thinks of as a kind of younger brother, alternately poking fun at him and imparting ( often questionable ) advice on life and women. When Cassidy leaves the precinct in 2000, Munch is briefly partnered with Monique Jeffries ( Michelle Hurd ), and then with Odafin Tutuola ( Ice - T ). He and the gruff, uncompromising Tutuola get off to a rough start, but gradually came to like and respect each other. Since being promoted to Sergeant at the beginning of season 9, Munch has taken more of a leadership role and does less investigating in the field, partially due to the fact that Tutuola was partnered with Detective Lake in season 9. After Lake 's departure in the season 9 finale, Munch begins working with Tutuola again, while occasionally acting as squad commander when Cragen was unavailable. In season 13, Munch is seen mostly in the precinct helping with interrogations and research, as Tutuola is partnered with Detective Rollins. He continues to act as squad commander when Cragen is absent. In season 14, Munch is temporarily reassigned to the Cold Case Unit, after solving a decade old cold child abduction case in the episode, `` Manhattan Vigil ''. He returns to SVU in the episode, `` Secrets Exhumed '', in which he brings back a 1980s rape - homicide cold case for the squad to look into. Munch filed his retirement papers after the events in the episode `` American Tragedy '', formally leaving in `` Wonderland Story ''. He subsequently accepted a position at the District Attorney 's office as an investigator. The character was first created for the NBC police drama Homicide : Life on the Street, where he worked as a homicide detective with the Baltimore Police Department. The character was based on Jay Landsman, a central figure in David Simon 's true crime book Homicide : A Year on the Killing Streets, a documentary account of the homicide unit 's operation over one year. After the series cancellation in 1999, the character was transferred to Law and Order : Special Victims Unit, having appeared within the original Law & Order in cross-over episodes. Within the series, it is eventually said he left Baltimore after his wife cheated on him with a friend. Munch has been the only fictional character played by a single actor to appear on eight different television shows : Homicide : Life on the Street, Law & Order, Law & Order : Special Victims Unit, Law & Order : Trial by Jury, The X-Files, Arrested Development, The Beat, and The Wire. He is also mentioned in UK TV series Luther. Donald Cragen Main article : Donald Cragen Portrayed by Dann Florek Episodes : `` Payback '' -- `` Amaro 's One - Eighty '', `` Perverted Justice '' Donald Cragen is the Captain of the Special Victims Unit. Florek originally portrayed the character from 1990 to 1993 in the original Law & Order series. During his Law & Order tenure, Cragen was investigated by internal affairs for corruption. During the investigation to prove his innocence, he discovered that he was being framed by his former captain and mentor, whom he turns in and is cleared by IAB. He was an alcoholic for much of his early career, but goes sober after pulling his service revolver on a taxi driver in a drunken rage. He has remained sober since, even after the death of his wife in a plane crash. Cragen was written out of Law & Order in 1993, as he is transferred to Anti-Corruption Task Force, occasionally making guest appearances on the show. The character was brought back full - time in 1999 to be the Captain of the Special Victims Unit. As SVU Commanding Officer, he is portrayed as a somewhat stern but understanding father figure to the detectives who work under him, often giving them a great deal of leniency because he trusts their ability to get results. Cragen departed at the end of `` Amaro 's One - Eighty '' after his girlfriend Eileen got two tickets for a six - month cruise around the world and he decided to use his unused leave time to carry him through until June. Brian Cassidy Brian Cassidy was portrayed by Dean Winters from 1999 to 2000 and 2012 to 2014. Main article : Brian Cassidy Portrayed by Dean Winters Episodes : `` Payback '' -- `` Disrobed '', `` Rhodium Nights '' -- `` Above Suspicion '', `` Undercover Blue '', `` Her Negotiation '' -- `` Downloaded Child '', `` Gone Fishin ' '' - `` Chasing Demons '' Brian Cassidy was a detective in the SVU during the series ' first season. The youngest and least experienced member of the precinct, he has a genuine desire to put rapists and child molesters in prison, but lacked the professional detachment necessary to deal with the often grisly sex crimes. He often has trouble concealing his anger and revulsion toward the cases he investigates and this created friction between him and his colleagues, made worse when they poke fun at his relative lack of sophistication. A genuinely talented and driven police detective, he makes a real effort to learn from the other members of the precinct, particularly Munch, whom he thinks of as a sort of older brother / mentor figure. He has a brief affair with Olivia Benson, and has trouble dealing with her after the relationship ends. Cassidy was written out of the show midway through the first season. Cragen sends him to interview a young girl who was repeatedly raped and brutalized, causing Cassidy to realize that he can not emotionally handle the types of crimes that a SVU detective must deal with on a daily basis. Cragen then offers to assist Cassidy with a transfer to another department, narcotics. After a twelve - year absence from the show, Cassidy returned in the season 13 finale, `` Rhodium Nights ''. He is working undercover as security personnel for Bart Ganzel, the owner of an escort service. When Amaro and Rollins go to speak to Ganzel, Cassidy confronts Amaro and punches him in the face. After Cassidy is arrested, he is in the interrogation room with Amaro when Benson walks in and sarcastically greets her old colleague, explaining to Amaro how Cassidy worked SVU in another `` century. '' Cassidy agrees to help them as long as they do n't blow his cover. After Cassidy helps SVU get insight on the war between Ganzel and an opposing escort service, he has to play both sides of the law as he refuses to sacrifice his three years of undercover work. In the season 14 premiere, Bureau Chief ADA Paula Foster reveals to Detective Benson that Cassidy is working undercover for her. Benson, along with Cassidy 's former SVU partner Sergeant Munch, meets with him on two different occasions to get information on the escort war. When Benson goes to Ganzel 's loft to speak with Cassidy again, they walk outside to what appears to be an attempted theft of Ganzel 's car. Benson gives chase to one person, while Cassidy and the car thief pull guns on each other. A patrol car pulls up, and two officers draw their weapons, as Cassidy identifies himself as police. As Benson returns to identify herself as police, the patrol officer shoots Cassidy twice. Benson calls for a bus and rides with him to the hospital, where he survives, as the bullets missed his main arteries. It is discovered that the officer who shot him was contracted by Ganzel to shoot Cassidy after Ganzel finds the bugs that the DA 's office had installed in his loft. Later, Cassidy and Benson share a kiss in his hospital room after Benson tells him she is n't the same person he knew years ago. In the episode, `` Undercover Blue '', Cassidy is accused of rape by a prostitute while he was undercover almost four years prior. It is revealed that Cassidy was being set up by the woman and her boss to make money off a lawsuit against the NYPD and the charges are dropped. Also in this episode, Munch says that Cassidy paid the price for having a relationship with a prostitute while undercover with Ganzel, as he was demoted from detective to an officer who works nights at a Bronx courthouse. Benson and Cassidy also are forced to reveal their romantic relationship in this episode when Amaro and Munch go to Cassidy 's apartment and find Benson there. Monique Jeffries Main article : Monique Jeffries Portrayed by Michelle Hurd Episodes : `` Payback '' -- `` Runaway '' Monique Jeffries was a police detective with Manhattan 's Special Victims Unit and was one of the initial detectives in the SVU squad. Earlier in the series, she is partnered with various detectives, including Brian Cassidy. Initially, she is only seen at headquarters, doing research and showing up in court for various cases to represent the department. After Cassidy 's departure in the middle of the first season, she partners with Detective Munch and begins going out on investigations. Shortly after this, she is physically and emotionally shaken when a car explodes while she is pursuing a fleeing suspect. Survival of the incident leaves her feeling `` restless '', and she has a one night stand with a man she recognized as a suspect in a previous sexual assault case the unit had investigated. After she confesses this to a department psychiatrist, who is working for a commission investigating problems in various police units, she is taken off active duty and ordered to receive treatment. Captain Don Cragen, feeling she has become `` reckless '' and `` a danger '' to herself supports the decision. At the end of the season 2 premiere episode, Detective Fin Tutuola shows up at the SVU precinct, and Jeffries asks if she can help him. Upon reading the folder Tutuola gives her, she realizes he is there to take her job. Finding desk duty intolerable, she cleans out her desk and leaves her gun and badge on the desk of Captain Cragen. In the second season, although she is shown in three episodes, it is revealed that she was reinstated and transferred to the Vice Unit. Danielle Beck Portrayed by Connie Nielsen Episodes : `` Clock '' -- `` Cage '' Detective Danielle `` Dani '' Beck is Detective Olivia Benson 's temporary replacement in season 8, while Benson is on an undercover assignment ( Mariska Hargitay was on maternity leave ). Dani had a husband, a cop named Mike Dooley, who was shot and killed in the line of duty. She and Stabler get off to a rocky start, but they eventually form a solid partnership. A turning point in their relationship occurs when they share a passionate kiss after celebrating a case at a bar, although post-kiss nothing more than increased sexual chemistry is ever implied. During a case involving child abuse, Beck tries to foster a traumatized adopted girl, who attempts to burn down her apartment and kill them both. Shaken, Beck tells Stabler she could not stand working in the Special Victims Unit anymore unless he asked her to stay. Stabler reluctantly says he can not make that decision for her, so she decides it would be best to return to her old post at the Warrants squad. Hargitay returned to her role as Benson in the following episode. Chester Lake Chester Lake was portrayed by Adam Beach from 2007 to 2008. Main article : Chester Lake ( Law & Order : Special Victims Unit ) Portrayed by Adam Beach Episodes : `` Outsider '', `` Screwed '', `` Alternate '' -- `` Cold '' Detective Chester Lake transferred to the Manhattan SVU from the Brooklyn Special Victims Unit at the end of the eighth season and was partnered with Detective Fin Tutuola. He is of Native American ancestry, specifically Mohawk, and speaks proudly of his ancestors, noting that many of them helped to build the city 's skyscrapers and subway tunnels. He also used to compete as an amateur mixed martial artist under the name `` Naptime '', but had to quit after tearing his ACL. Lake suffers from insomnia and often takes walks at night when he can not sleep. In the final episode of the ninth season, Lake begins attending meetings of individuals in Philadelphia who share information on `` cold '' murder cases. He later shoots and kills a fellow police officer, who was suspected of raping two illegal immigrant girls ten years ago, killing one. Lake disappears while his fellow detectives investigate. They are able to prove Lake killed the other cop in self defense after he was shot at himself by a second NYPD officer with a history of brutality. Lake is found, wounded, and taken to the hospital. The second officer, however, is released after the jury deadlocks. The officer is killed the same night and Lake is found standing over the body and makes no denial to his fellow SVU detectives. He is arrested and last seen in the series sitting handcuffed in a police car. It was confirmed on April 18, 2008 that Lake would not be returning to the series to reprise the role in the subsequent season. Nick Amaro Nick Amaro was portrayed by Danny Pino from 2011 to 2015. Main article : Nick Amaro Portrayed by Danny Pino Episodes : `` Personal Fouls '' -- `` Surrendering Noah '' Nicholas `` Nick '' Amaro is a NYPD detective who has transferred to the Special Victims Unit from Warrants and Narcotics. When Nick was little, Amaro 's father beat his mother. Nick 's father later fled to Miami, Florida ; he attributes his firm belief in divorce to this. He is fluent in Spanish, is married, with a young daughter named Zara, and has a living mother, Cesaria ( Nancy Ticotin ). His wife, Maria Grazie Amaro ( Laura Benanti ), is doing overseas reporting in Iraq. Since Maria has been deployed in Iraq, their relationship has been somewhat tense, although they always seem to work through their differences. Initially, Amaro did not see eye to eye with his new partner, Detective Benson, mainly because she was adjusting to having him as a partner instead of Elliot Stabler. After their rocky start, Amaro and Benson begin to have a mutual respect for each other and work well together. During his early days in SVU, Amaro has a tough time adjusting to the cases and tells Benson he has the urge to physically assault a suspect, but she tells him the better solution would be to ensure that the perpetrators never see the light of day. In the episode `` Hunting Ground '', Amaro saves Detective Benson and a kidnapped victim by shooting and killing a man. He is seen visibly shaken as it happened to be his first kill shot. In the episode `` Valentine 's Day '', he sees his wife go into an apartment of a man he does not know. In `` Street Revenge '', while trying to work a case of vigilante justice, he shadows his wife to see where she goes during the day ; he later gets into a heated argument with his wife at the SVU squad room ( after going to Philadelphia and assaulting a military friend of hers ), and she tells him she is seeing a psychiatrist because she is trying to adapt back into her old life. In the season 14 premiere, Amaro 's wife decides to take a job in Washington, D.C., citing that they need a break from each other. Amaro is clearly rattled by this and goes as far as to threaten to shoot Detective Brian Cassidy if Cassidy did not tell him for whom he was working undercover. This, along with his erratic behavior, causes the SVU detectives to be very cautious around him with sensitive information regarding Captain Cragen 's case. In `` Twenty - Five Acts '', Amaro seeks temporary SVU commanding officer, Captain Harris ( Adam Baldwin ), to let Amaro work their rape case solo, telling Benson that she needed a partner she could trust, Benson working the case with Rollins. In the episode, `` Undercover Blue '', Detective Cassidy is put on trial for rape while he was undercover. Amaro is called to the stand by ADA Derek Strauss and he is asked questions about his undercover work. When Cassidy 's lawyer questions him, he is forced to reveal that he had a romantic relationship with the sister of a drug lord he was investigating undercover. Munch then informs him that the NYPD brass is requesting he take a paternity test because the woman is claiming he has a son from the relationship. He goes to the woman 's house to confront her, but is denied by her boyfriend. Later, while watching the boyfriend pick his alleged son up from school, he witnesses the man complete a drug deal using the boy. Amaro then meets the boy and tells the woman that her boyfriend is using their son to deal drugs. After Cassidy apologizes to Amaro for what his lawyer did, Cassidy helps Amaro bust the boyfriend for drug dealing. The episode concludes with Amaro knocking on the woman 's door and her reluctantly letting him in. Amaro begins to show great concern when Rollins begins gambling again, and they begin to get close.

Portrayed by Donal Logue Episodes : `` Gambler 's Fallacy '', `` Beast 's Obsession '' -- `` Spring Awakening '', `` Undercover Mother '', `` Community Policing '' Lieutenant Declan G. Murphy is first introduced working as an undercover cop whom Rollins comes across while she 's on a gambling binge. Shortly after William Lewis escaped from prison, One Police Plaza appointed Murphy commanding officer of Manhattan SVU, deeming it inappropriate for Benson to lead the manhunt to recapture Lewis. Murphy 's reign as commanding officer continued after Lewis ' suicide at the request of One Police Plaza. Murphy was a strict and by - the - book CO, often checking behind the detectives ' backs, ensuring they were apprehending suspects correctly and often using his undercover expertise to lead the direction of investigations. Murphy 's strictness often caused him to bump heads with the detectives, mainly Amaro, who did not trust him. Morally, Murphy has shown to be flexible. When Benson was looking at perjury charges after Lewis ' suicide, he lied under oath and persuaded the grand jury not to pursue them, stating that Benson did what she had to do to save the girl that Lewis had kidnapped, whether what she had said on the stand had merit or not. However, when Amaro is arrested for his assault on a photographer investigated for child pornography and building a torture chamber that he claimed he used regularly, Murphy tells Amaro that he knows Amaro does n't value his advice, but to stand down and keep quiet, regardless of the circumstances. After the charges were dismissed, Murphy told Benson that he would do what he could, but he was not going to pull strings for Amaro, as he was unconvinced that Amaro 's career was worth saving. At the end of `` Spring Awakening '', Murphy tells Benson that he has been chosen for an undercover assignment and recommended to One Police Plaza that command of the SVU be returned to her. Subsequently, in the episode `` Undercover Mother '', Murphy 's undercover assignment is revealed after SVU takes down a sex trafficking ring. In the seventeenth - season episode `` Community Policing '', Murphy returns after finding out about Rollins ' pregnancy while he was `` 4,000 miles away in Serbia trying to take down a sex trafficking ring. '' Rollins reveals to Murphy that he is in fact the father of her child. Upon hearing this, Murphy lets her know that he is now here to stay, albeit temporarily ; however, he gives Rollins a secret cell number, and tells her that should she need him, he would be on a plane within an hour. Mike Dodds Portrayed by Andy Karl Episodes : `` Maternal Instincts '' -- `` Heartfelt Passages '' Sergeant Mike Dodds is introduced in the season 17 episode, `` Maternal Instincts '', as the son of Deputy Chief William Dodds ( Peter Gallagher ), who transfers to the 16th Precinct to serve as Lieutenant Ashley 's second - in - command. He is a war veteran, having enlisted after 9 / 11 and served in Special Forces. Immediately prior to his transfer, Dodds worked Anti-Crime, and before that, he worked out of the 71st Precinct. Dodds is a consummate professional and devoted to his work ; as a result, he takes some time to warm up to his new colleagues but he gradually comes to respect and like them. He is shot in the line of duty while pursuing serial killer Dr. Gregory Yates in upstate New York but eventually recovers. Only a few months into his tenure, he is offered a position with the joint terrorism task force by his father but decides to stay with SVU, boldly going against the Deputy Chief 's wishes ( the elder Dodds had meant for his son 's time at SVU to be nothing more than a career step ). In `` Manhattan Transfer '', Dodds is made Acting Commander of SVU after Lt. Olivia Benson is relieved of her duties. In the subsequent episode, Dodds leads SVU 's continued investigation into a sex trafficking ring while continuing to consult Benson. He happily returns command of SVU back over to Benson after the case is closed. In `` Heartfelt Passages '', Dodds is shot in the stomach during a hostage situation. He makes it through surgery, but he later suffers a stroke in the ICU and is put on life support. After its determined that Dodds is brain dead, he is taken off life support and dies. Both Chief Dodds and the entire SVU Squad were devastated by his death and Olivia Benson suffers from survivor 's guilt. It is shown a few months after the tragic event that the Deputy Chief still holds Olivia responsible for what happened to his son. As Olivia herself admits, `` he 's not wrong ''.

She serves as SVU 's ADA until the fourth episode of season 5, in which she survives an assassination attempt by a drug cartel 's hitman and subsequently enters the Witness Protection Program. In the season 6 episode `` Ghost '', she returned to testify against her assassin, but quickly disappears back into Witness Protection after the trial. She appeared in the 2006 short - lived Law & Order spinoff Conviction as Bureau Chief of the homicide unit. In season 10, she makes a surprise return to SVU as the temporary ADA, replacing ADA Greylek, for six episodes, starting with the episode `` Lead ''. Although Cabot was absent for the first four episodes of season 11, she becomes their permanent ADA in the fifth episode ( `` Hardwired '' ) after EADA Sonya Paxton entered court - ordered alcohol rehab. She left SVU in the season 11 episode `` Witness '' to work for the International Criminal Court to seek justice for rape victims in the Congo. She later returned in the season 13 premiere `` Scorched Earth '', in which Cabot is the lead prosecutor in a rape case against a man who is the favorite to become Italy 's next prime minister. She is the prosecutor in seven episodes, sharing the ADA duties with Casey Novak and Bureau Chief Mike Cutter.

Elizabeth Donnelly Elizabeth Donnelly was portrayed by Judith Light from 2002 to 2010. Main article : Elizabeth Donnelly Portrayed by Judith Light Episodes : `` Guilt '' -- `` Cold '', `` Persona '', `` Zebras '', `` Behave '' Elizabeth Donnelly was SVU 's Bureau Chief Assistant District Attorney from seasons 3 to 6. In the District Attorney 's office, she serves as the supervisor for ADA Cabot and her successor Casey Novak. Donnelly is elevated to judge in season 7. In the season 10 episode `` Persona '', Donnelly takes a leave of absence from her role as a judge and resumes her previous role as an Executive ADA to prosecute a cold case she was involved with in 1974, when a battered woman ( Brenda Blethyn ) murdered her husband. She admits to Benson that she was somewhat responsible for the woman absconding from custody and therefore took on the case due to `` unfinished business. '' Her role in the escape leads to mishaps in the justice system being termed `` doing a Donnelly '' for many years to follow. This episode calls attention to the difficulty Donnelly experiences as a woman working in the justice system. But the revelation that the fugitive had been pregnant at the time of her crime leads Donnelly to what, for her, is an act of leniency. She leaves the office, yet again, and returns to the role of a judge. From season 7 through 12, the SVU ADAs work without a Bureau Chief supervising their work, and are watched more closely by the District Attorney. In season 13, Executive ADA Michael Cutter is transferred from homicide to take over Donnelly 's former role as supervisor. Casey Novak Casey Novak was portrayed by Diane Neal from 2003 to 2008 and 2011 to 2012. Main article : Casey Novak Portrayed by Diane Neal Episodes : `` Serendipity '' -- `` Cold '', `` Reparations '', `` Blood Brothers '' -- `` Valentine 's Day '' Casey Novak was SVU 's Assistant District Attorney from seasons 5 to 9, replacing ADA Alexandra Cabot. Although she quickly loses her innocence when dealing with sex crimes, she still shows uneasiness when dealing with the gray areas of human involvement, preferring the letter of the law to the messiness of each individual reality. Nonetheless, Novak has a 71 percent success rate in the cases she prosecutes, whereas the average for prosecutors is 44 percent. After initial hesitation, she becomes particularly close to Stabler as they bond over being Catholic and a love for sports. It is revealed that in her final year of law school, Novak was engaged to a man, Charlie, who suffered from schizophrenia. She ended the relationship when his symptoms became so severe she felt she could no longer be intimate with him. In 2002, Charlie attacked her in her home during a psychotic episode. She convinced the police not to press charges, but ended the relationship. He eventually became homeless, and was found dead as a `` John Doe '' in the spring of 2007. She developed a deep compassion for the mentally ill afterward, but still feels guilty for not being able to help him, as shown in season 9 's `` Blinded. '' She states that she is a big supporter of the U.S military. She says that her father was an M - 60 Door Gunner on a Huey during the Vietnam War. His helicopter crashed three times and he received a Purple Heart. In season 9, her final year as the SVU ADA, she grew increasingly more reckless and unsure in her prosecution. It is implied that friend and former boss Liz Donnelly aided in her censure, leading to her replacement by ADA Kim Greylek in season 10. It is revealed that Novak was censured for three years and subsequently re-hired by the DA 's office. This is explained in the season 12 episode `` Reparations '', where she returns to SVU as their temporary ADA to prosecute a rape case. She is opposed by Law & Order : LA Deputy District Attorney Jonah Dekker who is representing the defendant. Casey not only finds herself at odds with Dekker, but also Judge Petrovsky, to whom she had previously lied in the season 9 finale ( `` Cold '' ), which ultimately led to her censure. ADA Novak returned as a recurring character, along with ADA Cabot, in season 13. She was last seen as the lead prosecutor in `` Valentine 's Day '', in which she goes up against Defense Attorney Marvin Exley, who is defending a woman who seems to have fabricated her own abduction. Kim Greylek Main article : Kim Greylek Portrayed by Michaela McManus Episodes : `` Trials '' -- `` Lead '' Kim Greylek was the SVU 's Assistant District Attorney who replaced Casey Novak at the beginning of season 10. Greylek previously worked in the U.S. Department of Justice 's Office on Violence Against Women in Washington, D.C. where she had the nickname of `` The Crusader. '' A dogged prosecutor, she pushed the detectives to make cases for the sake of politics in favor of pursuing actual offenders. She can be unrelenting, threatening to charge a defendant with a hate crime for raping two women in the season 10 premiere, and having a teenage boy charged with assaulting a police officer so he can be tested for HIV. In the episode `` Babes '', Greylek also angers a woman believed to be involved with a young girl 's suicide, but she was found not guilty. After gloating about her innocence, the woman attacks Greylek for correcting her about being `` innocent '' and to wash the blood off her hands before holding her daughter 's baby. When the officers pull the woman off her, Greylek tells Stabler to charge her with assault. But Greylek also has a softer side, as she warns Stabler to get a good defense attorney after his daughter Kathleen ( who was dealing with bipolar disorder issues ) is charged with breaking & entering and theft, because the DA 's office will prosecute her. Greylek also rushes to get justice for three women who were drugged and raped by a man obsessed with pornography in the episode `` Smut ''. Greylek seeks justice when a man is brutally beaten outside a strip club with the man 's ex-wife and 13 - year - old transgender daughter Hailey as the prime suspect. Before the case gets to trial, Benson and Stabler discover that it was Haley 's guidance counselor who committed the crime. During the trial, it is discovered that the guidance counselor is also a transgender woman and that is why she tried to help Haley. After appearing in only 14 episodes, Greylek was written out of the series in the episode `` Lead '' ; in the middle of a trial where Pediatrician Gilbert Keppler ( Lawrence Arancio ) is found guilty of sexually assaulting four of his male patients. She is last seen doing a press conference with Cragen, Benson, and Stabler on the steps of the courthouse while the doctor 's attorney hands the SVU squad a lawsuit for failure to take action against Keppler immediately. Later in the episode, Benson and Stabler discover the doctor murdered in his home. The detectives hold CSU out of the house until Cragen and Greylek arrive.

Working in the Appeals bureau, she was the first to get a Capital Conviction in New York when the then newly elected Governor Pataki brought back the death penalty in 1995. Paxton was sent to SVU by DA Jack McCoy to `` clean house '' in the `` he - said, she - said unit '' due to too many convictions being overturned. However, things started out rocky as she butts heads with the SVU team, particularly Detective Stabler. In the second episode `` Sugar '', she and Stabler get into a heated argument after Paxton calls the suspect 's lawyer after he declines his right to counsel twice. In the fourth episode `` Hammered '', Paxton is prosecuting a case where a man drank heavily and murders the woman he met at the bar. The defense blames alcoholism for the murder during the trial. Intending to use a computer - generated video mockup of the crime, Paxton accidentally plays a version in which the defendant 's face is superimposed onto the attacker. Paxton is embarrassed and meets Benson and Stabler at a bar where she is seen drinking. The following morning, she arrives 45 minutes late to the mistrial hearing, appearing distraught and blaming a `` fender bender ''. Judge Moredock asked if she needed medical help, but the defendant pointed out that she was drunk. Judge Moredock ordered Benson to come with a breathalyzer, which revealed her blood alcohol level was. 082, resulting in a mistrial. Moredock ordered Paxton to seek treatment, which prompted her departure. At the end of the episode, she returns to the SVU precinct and apologizes to the team, stating that she intends on making amends to each and every one of them. She later appears in the season 11 episode `` Turmoil '', meeting ADA Cabot outside the courtroom after Cabot discovers she is being investigated by the state bar. Paxton tells her to watch out for Benson and Stabler, because they are only loyal to each other.

Paxton and Stabler go at it again, with Stabler telling her to `` go have a drink. '' In the seventeenth episode ( `` Pursuit '' ), she returns again to help out an old friend, Alicia Harding, who starts receiving personal threats from her stalker. Paxton tells the SVU squad that she has been working to find Harding 's missing sister for decades as it was her case. She releases confidential case information to Harding, which puts Harding in danger. Benson and Tutuola go looking for Paxton at an Alcoholics Anonymous meeting to reprimand her for giving out the information. Benson makes a shocking discovery when entering the women 's restroom as Paxton is bleeding out on the floor. As Benson tries to help her, Paxton says `` It 's okay, I got him, '' and she dies in Benson 's arms. M.E.

She first appears in the 21st episode of the season, `` Torch '', in which McCoy directs her to handle a case in which two young girls were killed in a fire. Stabler and Benson show up at the crime scene and Stabler is shocked to see his old partner and more surprised to know she now works for the DA 's office. Benson believes Marlowe only took the job as SVU 's ADA so that she could work with Stabler again. In the following episode, `` Ace '', Marlowe and Captain Cragen clash over the way to handle a case in which a baby - trafficking ring is discovered and a young woman and her baby are in danger. Marlowe orders Benson and Stabler to catch the ring 's leader in the act, while Cragen wants ESU to take the perp at his warehouse. Cragen remarks to Marlowe, `` You 're the boss in court counselor, not here. '' Marlowe leaves the precinct only to have Cragen follow her outside, where he reminds her of `` why she really retired '' back in 1995 : when she was a lieutenant she had sent two undercover detectives who later died in an attempt to arrest a drive - by murderer. Marlowe responds it was a `` Command decision. '' Cragen 's detectives do arrest the ringleader, while Cragen saves the young woman in the warehouse. Marlowe is able to convict the leader by using his delivery doctor 's testimony, which he delivered in the judge 's chambers for protection. In the season 11 finale, `` Shattered '', Marlowe is taken hostage, along with Detective Benson and Dr. Warner, in the morgue by a distraught mother of a dead boy. The mother shoots Dr. Warner and Benson and Marlowe must take action to save her life. In talking the mother down, Marlowe says she knows what it is like to be in pain as she reveals that she was diagnosed with an `` aggressive '' type of cancer and had a bilateral radical mastectomy a year before taking the job at SVU. Marlowe makes the mother drop the gun by picking up the dead boy and saying that he needs his mother and handing him to her. Marlowe is last seen looking increasingly upset. ADA Gillian Hardwicke replaces Marlowe as SVU 's permanent ADA at the beginning of season 12. Entertainment Weekly reviewed Stone 's performance as a `` great presence '', and having `` had to revive her best... tone to sell hokey lines '' in a series it described as `` mawkish and overwrought. '' Sherri West Portrayed by Francie Swift Episodes : `` Bullseye '', `` Behave '', `` Delinquent '', `` Smoked '', and `` Double Strands '' Sherri West is brought in as a temporary ADA to start season 12. West first appears in the second episode, where she is the prosecutor on a case where a pedophile hiding in plain sight is believed to have started going after young girls again. When the suspect is brutally beaten in the SVU holding cell by an officer, West assures the judge that violence against the defendant wo n't occur again. West next appeared in the third episode, `` Behave '', in which Detective Benson goes to the ends of the Earth for a rape victim named Vicki Sayers ( Jennifer Love Hewitt ) to ensure that Bill Harris ( James Le Gros ), her rapist, is put away. West returned in the 23rd episode, `` Delinquent ''. When SVU detectives find Hunter Mazelon ( Sterling Beaumon ) naked and asleep in a young woman 's bed, West tells them that she ca n't charge Hunter with a sex crime but he can be charged with burglary 1 and criminal trespass 2, among other charges. When Hunter says during his arraignment that Detective Stabler molested him after handcuffing him, West 's case is in shambles since there was also no actual victim. West manages to get Mazelon to allocute, which he did falsely, but Stabler wished for West to call for a recess. Detectives Tutuola and Stabler commented about how they have been burning through ADAs and maybe West cut the deal to cover Stabler so that they would like her. In the season 12 finale `` Smoked '', a rape victim was murdered days before her trial was set to start. West is called again and pushes Detectives Benson and Stabler to find the victim 's murderer. Benson and Stabler, with West 's help, discover the murder was orchestrated by the rapist, a friend, and a greedy ATF Agent. West did not manage to convict anyone because they were brutally killed by the victim 's daughter in the SVU squad room, before Detective Stabler was forced to shoot her. In the fourth episode of season 13, `` Double Strands '', Sherri West appears back in the SVU precinct, except as a defense attorney because they `` offered her a better deal.

She often gets into conflict over cases with Detectives Benson and Stabler ; with Benson over a case where a woman was raped as a teenager and she began seeking revenge on her attackers, branding them with hot clothes hangers. She and Benson also clash when Vivian Arliss ( Maria Bello ) -- who gave custody of her son Calvin ( Charlie Tahan ) to Olivia -- is a suspect in a string of burglaries. Hardwicke and Stabler get into conflict over a case where presumably, a boy named Nicky Roberts, shot and killed his abusive stepfather ; the case eventually dropped because both Nicky and his mother admit to killing him, evidence not proving one or the other. In `` Penetration '', Hardwicke convicts a man who raped FBI Agent Dana Lewis while she was undercover, at the request of Brian Ackerman ( J.C. MacKenzie ), who was angry at Lewis for killing his son Kyle in the season 7 episode `` Raw ''. In her final episode, `` Bombshell '', Hardwicke attempts to convict twin - siblings Cassandra ( Rose McGowan ) and Doug ( Ryan Hurst ) -- who are actually in a sexual relationship -- for their involvement in a man 's brutal stabbing along with fraud crimes in New York and Miami. They are released on bail due to lack of evidence, which leads to Doug 's murder by the man in love with Cassandra. Hardwicke is mentioned in the episode `` Reparations '' as Detective Tutuola says she is at a convention in Miami, before ADA Casey Novak returns as their temporary prosecutor. Sherri West then assumed the temporary ADA role for the final two episodes in season 12. It is unknown if Hardwicke ever returned to New York.

In `` True Believers '', Cutter takes the lead in a case where a college music student ( Sofia Vassilieva ) is raped at gunpoint by a drug dealer. Powerful defense attorney Bayard Ellis ( Andre Braugher ) played the `` race card '' defense and Cutter fails to get a guilty verdict on the case due to the fact that Detectives Tutuola & Rollins had a faulty identification by the victim by frisking three identical suspects, Detectives Benson & Amaro are not on the same page when Amaro sees the suspect sling a gun under his sofa while they attempt to arrest him in his home, and the victim 's credibility being questioned because she had a one - night stand with her music instructor.

Haden and the SVU detectives are threatened by the CEO ( portrayed by John Doman ), but Haden dismisses the threat, telling Detective Benson, `` This is what I live for.

As the case develops, so does their relationship, as they share dinner and a kiss at the end of the episode. In the following episode, `` Father 's Shadow '', Haden offers to take Olivia to dinner but she respectfully declines, citing she was still on duty and joking there would be a possible conflict of interest. Later, Haden shows up at the scene of a hostage situation, in which Benson is trying to talk the teenage boy down.

He becomes SVU 's resident psychiatrist in season 3 after he was originally on loan to the squad towards the end of season 2. Though he is liked and respected by the SVU detectives and they generally defer to his professional judgment, his diagnoses sometimes hinder prosecutions, particularly where he finds mental illness, making defendants either not fully responsible for their crimes, or not fit to stand trial. This makes him a constant pain for the ADAs who are trying to prosecute the offenders. He frequently observes interrogations of suspects, advising detectives on how to best interact to obtain a confession. Very little is known about Huang 's personal life, other than that he is gay, which he noted in season 11 's `` Hardwired '', has a sister ( noted in `` Inheritance '' ), and that he speaks Cantonese and Mandarin. Dr. Huang was last seen in a main role during the season 12 episode `` Bombshell '' in which he helps Benson and Stabler get information out of a homeless man. The reason for his departure is not revealed until the season 13 episode `` Father Dearest '' in which Dr. Huang returns to the SVU squad temporarily to aid in an investigation and tells them about his new assignment in Oklahoma City. Huang returns to New York in the season 14 episode, `` Born Psychopath '', and helps the SVU detectives with a case involving a young boy who has become increasingly violent towards those close to him. He diagnoses the boy with Antisocial personality disorder and makes arrangements to get him into a treatment facility. After not appearing in season 16, the first season he did not appear in since joining the show in season 2, Huang returns in the season 17 episode, `` Depravity Standard. '' He tells Benson that he took early retirement from the FBI in order to return to New York, where he is now doing private consulting.

Warner is held hostage with Detective Stabler at a bank where the hostage taker 's father is the manager.

In the season 11 finale `` Shattered '', she is held hostage in her own morgue with Detective Benson and ADA Marlowe and is shot by the woman holding them hostage. She talks Benson through life - saving techniques before the woman lets her go to get real medical attention. She is well liked by the SVU squad, though briefly argues with Stabler when he accuses her of botching a DNA test on Benson, expected to absolve her of a homicide, before she discovered the DNA was intentionally doctored to make Benson look guilty. She served as a doctor in the U.S. Air Force during the Gulf War and is married with a daughter. Emil Skoda Emil Skoda was portrayed by J.K. Simmons from 1997 to 2010 ( Law & Order ).

She 's forced to blow her cover and reveal herself as a Federal Agent during the trial against the group 's leader when she shoots and kills the leader 's son before he could kill Stabler. She tries to apologize for her actions after the case is over, but Munch holds no grudge. Agent Lewis specializes in undercover work, often working under assumed identities for weeks or even months at a time. While working undercover, she uses the name Star Morrison and speaks with a Southern accent ( though the actress herself is not from the South ). In the season 8 premiere `` Informed '', she shows up in New York again when Detective Benson is hounding her eco-terrorism informant to tell her about her rape. Lewis and Benson must find the informant after she goes missing and stop her from conducting a terrorist bombing. Lewis mentions to Benson that she calls her informant `` Peggy Sue '' because she reminds Lewis of her baby sister, Margaret. In her last appearance, Lewis tells Benson and Stabler that her family ( husband and children ) is currently living in Europe to protect them from criminals who attempt to retaliate against her. One of these criminals, the leader of the aforementioned supremacist group, ordered a fellow inmate to attack and rape her in the season 12 episode `` Penetration ''. Elliot Stabler has been injured each time she has worked with them, by gunshot in season 7, by explosives in season 8, and by gunshot again in season 12 which was the only injury she was directly responsible for.

Lewis accompanies Benson and Amaro back to Manhattan, where she observes the interrogation and pleads with Captain Cragen to let her have a shot at the suspect after the detectives could not get the man to admit to killing the fifth victim. When Cragen obliges, Lewis sweats the suspect into admitting he was at the scene when the victim was murdered. Amaro begins to question the confession when the boyfriend of the victim comes to the precinct and Lewis says that he was an old friend from when they date in college at Tulane University. Pieces of the confession begin to fall apart as Munch and Rollins finds evidence missing in the cold case file and the boyfriend of the victim admits to having a romantic relationship with Agent Lewis. Amaro then gets the suspect to recant his confession and Lewis begins to seem increasingly panicked. Cragen gets Lewis to believe that the handicapped suspect had an accident and he will be awhile before her and Benson could re-interview him. As Benson begins to ask Lewis questions, Lewis realizes that Benson 's questioning seemed interrogation - like. Benson and Amaro begin to ask Lewis pressing questions about the nature of Lewis ' relationship with the victim and her boyfriend at the time. They get her to admit they had a several - month - long romantic relationship, which subsequently got Lewis pregnant. After he forced Lewis to get an abortion, she found out that he asked the victim to marry him. Lewis, in tears, admits she went to the victim 's home, and after the victim taunted Lewis with the fact he asked her to marry her, she says she blacked out. She says that when she came to, the girl was dead. She tells Benson, who is clearly shocked and distraught, that she is so sorry. Cragen enters the room with a pair of handcuffs and tells Lewis she is under arrest for the murder. Amaro grabs the handcuffs and takes her into custody. Resigned to her fate, she cooperates, repeatedly saying, `` I understand, '' as tears continue rolling down her cheeks. Special Agent Dean Porter Portrayed by Vincent Spano.

He later breaks into Detective Benson 's apartment and tortures her before later abducting her to torture and rape her at an isolated location, killing a traffic cop and his own defense attorney 's parents in his travel. Eventually the police catch up to Lewis and Benson, after Benson managed to break free of her restraints and incapacitate him.

Lewis represents himself and maneuvers to force Benson to take the stand and tell everyone what he did to her and what she did to him ; crippling him in one leg, damaging numerous internal organs, and even deafening him in one ear, after she had already handcuffed him to a bed post. Benson lies and denies that she had him restrained, that he had broken free and she had to harm him to subdue him ; this drives Lewis into a rage during his cross testimony with her. Lewis is found not guilty on the rape charge but guilty on the abduction charge, as well as assault on a police officer.

It winds up where Olivia has to take the last bullet, thinking he is about to kill her ; he stands beside her and quickly shoots himself in the head with his left hand which causes reasonable doubt, making Internal Affairs believe Benson shot and killed Lewis, but the charges against Benson are later dropped.

At the Kings County morgue, Benson asks if she can take one last look at Lewis ' dead body before he 's rolled back into the cooler.
