Luis Alfredo Garavito Cubillos, also known as "La Bestia" ("The Beast") or "Tribilín" (named after Disney character "Goofy"'s Latin American Spanish name) is a Colombian rapist and serial killer.
 In 1999, he admitted to the rape, torture and murder of 147 young boys.
 His victims, based on the locations of skeletons listed on maps that Garavito drew in prison, could eventually exceed 300; Garavito continues to confess to more murders.
 He has been described by local media as "the world's worst serial killer".
 According to the Attorney General's Office and various judicial bodies, Luis Alfredo Garavito is the "second serial killer of the world."
 Likewise, the judicial body ruled that all Garavito's sentences total 1853 years and nine days in jail.
Charles Edmund Cullen (born February 22, 1960) is a former nurse who is the most prolific serial killer in New Jersey history and is suspected to be the most prolific serial killer in American history.
 He confessed to authorities that he killed up to 40 patients during the course of his 16-year nursing career.
 But in subsequent interviews with police, psychiatric professionals, and journalists Charles Graeber and Steve Kroft, it became clear that he had killed many more, whom he could not specifically remember by name, though he could often remember details of their case.
 Experts have estimated that Charles Cullen may ultimately be responsible for 400 deaths, which would make him the most prolific serial killer in American history.
The Daytona Beach killer is an American serial killer responsible for the murders of four women in the Daytona Beach, Florida area from December 2005 to December 2007.
 The killer has never been apprehended.
 The involvement of a serial killer was feared after the discovery of the first three victims.
Cold North Killers: Canadian Serial Murder is a 2012 Canadian non-fiction book written by Lee Mellor and published by Dundurn Press.
 It documents the lives of sixty Canadian serial killers, with the earliest being Edward H. Rulloff and the most recent being Russell Williams.
 The book uses Katherine Ramsland's interpretation of what constitutes a serial killer—someone who has killed at least two people on two separate occasions, and who attempted to or likely would have killed again—as outlined in her 2007 book "The Human Predator".
 "Cold North Killer's" own definition of what constitutes a Canadian serial killer includes both Canadians who committed murder abroad (such as Keith Hunter Jesperson and Gordon Stewart Northcott) and non-Canadians who committed murder in Canada (like William Dean Christenson and Earle Nelson).
My Brother the Serial Killer is a 2012 American television documentary about serial killer Glen Rogers, otherwise known as the "Casanova Killer", who was convicted for a series of murders and arsons.

 "My Brother the Serial Killer" received widespread media attention for Clay's claims that his brother was responsible for the 1994 murders of Nicole Brown Simpson and Ronald Lyle Goldman.

The Sun Hill Serial Killer was a major storyline from ITV's cop show "The Bill".
 Known originally as the "River Murders", the storyline spanned several months in 2002 and served as the exit for popular cast regular Cass Rickman (played by Suzanne Maddock).
 It was the first of several serial killer storylines from the show.
 Events came to a head in the New Year of 2003, when Acting DI Samantha Nixon discovers the truth and is taken hostage by the serial killer, before a final confrontation in which she is overpowered by DC Duncan Lennox, charged and thrown into the cells at Sun Hill Station.
Richard Leonard Kuklinski (April 11, 1935 – March 5, 2006) was an American contract killer and serial killer who was convicted of murdering five people, though he likely killed at least several dozen more.

Computer bridge is the playing of the game contract bridge using computer software.
 After years of limited progress, since around the end of the 20th century the field of computer bridge has made major advances.
 In 1996 the American Contract Bridge League (ACBL) established an official World Computer-Bridge Championship, to be held annually along with a major bridge event.
 The first championship took place in 1997 at the North American Bridge Championships in Albuquerque.
 Since 1999 the event has been conducted as a joint activity of the American Contract Bridge League and the World Bridge Federation.
 Alvin Levy, ACBL Board member, initiated this championship and has coordinated the event annually since its inception.
 The event history, articles and publications, analysis, and playing records can be found at the official website.
