## History

### On OC

Sirenko gets approached by Cosgrove and Shaw where Cosgrove grabs him and threatens him. Shaw gets Cosgrove to leave Sirenko alone. Stabler then approaches Cosgrove where he tells Cosgrove that he is ruining his case against Sirenko. Stabler told Cosgrove that the Organized Crime Control Bureau had been investigating Sirenko for six months. Cosgrove tells Stabler that Sirenko murdered a fifteen-year old girl. Stabler then becomes hostile towards Cosgrove before calming down. Stabler and Bell inform Cosgrove and Shaw about their investigation against Sirenko and how he was involved in a drug trafficking ring which was involved in serious criminal activity. Stabler and Cosgrove then put all their differences aside to work the case against Sirenko. Stabler then approaches Vince at the bar where he makes Vince clone Sirenko's phone. Later, Stabler manages to have Sirenko's phone cloned with Jet and Vince's assistance. Jet then finds surveillance footage at the yacht where Ava escaped from and saw that Sirenko was there with another man and Ava and a woman and another girl. Stabler and Benson then realise that Ava's pimp was a woman and arrested her at her home. (OC: "Gimme Shelter")

### On SVU

After finding out about the girl who was with Ava on the yacht, Sirenko manages to get ID'd by the girl who was named Nicole. As a result, Sirenko's residence was raided by a team of police who assumed that he was armed. Benson finds scratches on the floor of Sirenko's home and suspects that there might be a secret room. Stabler and Cosgrove then move a shelf and find a secret storage space. Benson then discovers the materials used to create the bomb. Benson orders everyone to turn off their radios. Sirenko is nowhere to be found and the team call the Joint Terrorism Task Force. Later, Vince stands in an alley smoking while under surveillance by the cops. Sirenko drives his van towards Vince. Sirenko tells Vince that he wants to go inside the garage and Sirenko makes Vince go into an elevator. Vince then follows Sirenko into the basement and Sirenko interrogates Vince. When Vince realises he is in danger, Vince attempts to flee but Sirenko attempts to shoot Vince. Vince continues to call for help but Sirenko starts beating up Vince. Sirenko then shoots Vince and runs away to avoid arrest. Stabler then interrogates Sirenko's henchmen and tries to get information about Sirenko's whereabouts. Jet then finds Sirenko's van which has been in front of the same address in Queens seven times. Stabler then catches a guy named John Kent who reveals that Sirenko is blackmailing him. Kent reveals that he works at a hotel downtown and that Sirenko made him give him security information. Sirenko then sets a ten-minute timer on the bomb. After everyone evacuates the building, Cosgrove chases after Sirenko despite the evacuation order. Cosgrove catches Sirenko just as the bomb goes off. Sirenko then disappears again and Stabler sends men in all directions to search for Sirenko. Rollins then finds Sirenko near a subway and requests for backup. Stabler then spots Sirenko as well. Sirenko then takes hostages in a bank. Sirenko demands an SUV with bulletproof glass or he will shoot a young girl in the head. After a shootout with the cops, Sirenko drops the hostages and Stabler holds him at gunpoint. Cosgrove stops Stabler from killing Sirenko. (SVU: "Gimme Shelter")

### On L&O

Price tells McCoy about the evidence against Sirenko and McCoy says that the two murders alone are worth a life sentence for Sirenko. Price doesn't get why Sirenko would make an international political statement. Maroun told Price that they know Sirenko killed Ava and Vince and planted the bomb and asked if it really matters why he did it. Price says it is crucial if they are missing something. Later, after finding a link between Sirenko and Rublev, Sirenko eventually talks and reveals that he worked with Rublev. Sirenko claims that he feels bad about Ava but Price doesn't want to hear it. Sirenko explains how Ava was recording with her phone and how she ran away after Rublev hit her. Rublev told Sirenko that Ava was going to the police and that Sirenko should kill Ava. Sirenko's lawyer wants to drop most of the charges and take life with parole off the table. Sirenko then gets 20 years in prison. Maroun tells them that she hopes Sirenko gets stabbed in prison. Later, Sirenko testifies and the defense attorney implies that Sirenko is a career criminal who cannot be trusted. Sirenko claims that just because he kills people doesn't mean he's a liar. After Rublev gets murdered before a conviction, Sirenko gets his end of the deal and gets sentenced to 20 years in prison. (L&O: "Gimme Shelter")
