Clifford Robert Olson Jr., known as the "Beast of British Columbia," was a Canadian serial killer who murdered 11 children and teenagers in British Columbia between November 1980 and July 1981. His victims, eight girls and three boys, ranged from nine to 17 years old and were abducted from communities around Vancouver and the Lower Mainland. Olson was arrested in August 1981 after police surveillance caught him attempting to pick up two young hitchhikers. He pleaded guilty to 11 counts of first-degree murder in January 1982 and received 11 concurrent life sentences with no parole eligibility for 25 years. He remained imprisoned until his death from cancer in September 2011.

Colin Ireland became one of the United Kingdom's most infamous serial killers after murdering five gay men in London over a seven-week period in 1993. Seeking notoriety, Ireland later admitted he deliberately set out to become a serial killer after reading an article suggesting Britain had none. Nicknamed the "Gay Slayer," he targeted men he met in London pubs before strangling them in their own homes. His brief but deadly murder spree shocked Britain and remains one of the country's most disturbing examples of predatory serial homicide.

David Berkowitz, known as the “Son of Sam,” is an American serial killer responsible for a series of shootings in New York City between 1976 and 1977. His crimes created widespread fear and led to one of the largest manhunts in the city’s history. Berkowitz gained notoriety for sending letters to police and media, claiming responsibility for the attacks. He was later arrested, confessed, and sentenced to multiple life terms.

Dennis Andrew Nilsen became one of the United Kingdom's most infamous serial killers after murdering at least 15 young men and boys in London between 1978 and 1983. Often referred to as the "Muswell Hill Murderer," Nilsen lured vulnerable victims to his home before strangling them and keeping their bodies for extended periods. His crimes were uncovered only after human remains blocked drains at his apartment building, leading to one of Britain's most shocking homicide investigations.

Dennis Rader, known as the BTK Killer (Bind, Torture, Kill), is an American serial killer who murdered ten victims in Kansas between 1974 and 1991. He targeted individuals in their homes, carrying out controlled and methodical attacks. Rader evaded capture for decades while maintaining a normal public life. His case gained notoriety due to his communication with media and law enforcement, and his eventual capture in 2005 following a forensic breakthrough.

Edward Theodore Gein became one of the most infamous killers in American history after murdering two women and exhuming numerous bodies from local cemeteries near Plainfield, Wisconsin, during the 1950s. Although convicted of only two murders, the disturbing discoveries inside his farmhouse—including items fashioned from human remains—made Gein a cultural phenomenon whose crimes inspired characters such as Norman Bates, Leatherface, and Buffalo Bill. His case remains one of the most extensively studied in criminal psychology.

Edmund Emil Kemper III, known as the "Co-ed Killer," became one of America's most notorious serial killers after murdering ten people between 1964 and 1973, including his grandparents, six female college students, his mother's friend, and finally his own mother. His intelligence, willingness to discuss his crimes in detail, and extensive interviews with FBI profilers made him one of the most extensively studied serial killers in criminal psychology.

Edward "Jake" Wagner admitted participating in the Pike County massacre, one of the deadliest family murder cases in Ohio history, by pleading guilty to murdering eight members of the Rhoden family in April 2016. Prosecutors established that Wagner, together with his parents Angela Wagner and George "Billy" Wagner III and his brother George Wagner IV, planned and carried out the coordinated killings during a custody dispute involving his young daughter with Hanna Rhoden. In exchange for avoiding the death penalty, Wagner agreed to testify against his family members and became the prosecution's key witness during their trials. He is serving eight consecutive life sentences without the possibility of parole.
