Paul Kenneth Bernardo became one of Canada's most infamous serial killers after committing a series of violent sexual assaults and the murders of three young women between 1987 and 1992. Before his arrest, Bernardo was responsible for numerous unsolved sexual assaults in the Toronto area, earning the nickname the "Scarborough Rapist." Alongside his wife, Karla Homolka, he murdered Tammy Homolka, Leslie Mahaffy, and Kristen French. His conviction remains one of the most significant criminal cases in Canadian history.

Paul Charles Denyer became one of Australia's most infamous serial killers after murdering three young women in Melbourne's bayside suburb of Frankston between June and July 1993. His crimes created widespread fear throughout Victoria, leading to one of the state's largest homicide investigations. Following his arrest, Denyer pleaded guilty to the murders and was sentenced to life imprisonment with a non-parole period. He remains incarcerated and is one of Australia's most notorious convicted serial killers.

Paul Edward Hicks became known in Ohio criminal cases after being convicted in 2025 for the 2001 murder of his estranged wife, Regina Rowe Hicks. The case remained unresolved for more than two decades before prosecutors finally secured a conviction, turning the investigation into one of the region’s most significant cold case homicide prosecutions. Born on July 18, 1955, in Willard, Huron County, Ohio, Hicks was accused of killing Regina during a period of marital separation and escalating personal conflict. Investigators later alleged he attempted to conceal the crime and avoid responsibility for years while the case remained unsolved. The eventual conviction drew major attention because of the extraordinary delay between the killing and the courtroom outcome, highlighting advances in investigative persistence, forensic review, and cold case prosecution strategies.

Pedro López became one of the deadliest serial killers in modern history after confessing to the murders of hundreds of young girls across Colombia, Ecuador and Peru during the 1970s and 1980s. Nicknamed “The Monster of the Andes,” López terrorized vulnerable communities throughout South America by targeting poor and isolated children, many of whom disappeared without immediate investigation. His crimes shocked the world not only because of the staggering number of alleged victims, but also because López appeared calm and cooperative while confessing to investigators. Despite claiming responsibility for hundreds of murders, he ultimately served a relatively short prison sentence before disappearing after his release, creating ongoing fear and controversy surrounding his whereabouts and possible later crimes.

Peter William Sutcliffe, known worldwide as the "Yorkshire Ripper," became one of the United Kingdom's most infamous serial killers after murdering 13 women and attempting to murder seven others between 1975 and 1980. Operating across Yorkshire and Greater Manchester, Sutcliffe evaded capture for more than five years despite one of the largest police investigations in British history. His crimes generated widespread fear, exposed major investigative failures, and permanently changed homicide investigations in the United Kingdom.

Rabbi Fred Neulander became one of America’s most infamous religious figures convicted of murder after orchestrating the 1994 killing of his wife, Carol Neulander, in a case widely known as “The Synagogue Murder-For-Hire.” A respected rabbi and prominent spiritual leader in Cherry Hill, New Jersey, Neulander shocked the nation after prosecutors alleged he hired hitmen to murder his wife while maintaining the outward image of a devoted husband and community figure. The case generated enormous national attention because of Neulander’s status within the Jewish religious community and the calculated nature of the murder-for-hire plot. Investigators later uncovered evidence involving secret affairs, financial motives, and hired attackers who staged the killing to resemble a burglary gone wrong. The combination of religious authority, hidden double lives, and contract killing allegations made the case one of the most notorious clergy-related murder prosecutions in modern American criminal history.

Randy Steven Kraft became one of America's most infamous serial killers after murdering at least 16 young men and boys across California, Oregon, and Michigan between 1972 and 1983. Often referred to as the "Scorecard Killer" because of a coded list discovered in his possession after his arrest, Kraft is suspected by investigators of murdering more than 60 victims. Convicted of 16 murders, he was sentenced to death in California, where he remains incarcerated.

Rex Heuermann became one of America’s most infamous alleged serial killers after being charged in connection with the Gilgo Beach murders on Long Island. The architect from Massapequa Park shocked the United States because prosecutors alleged he secretly murdered multiple women for years while outwardly living as a married family man and successful New York professional. The Gilgo Beach investigation became one of the most heavily publicized serial killer cases in modern American history after human remains were discovered along Ocean Parkway near Long Island’s South Shore. Authorities later accused Heuermann of targeting vulnerable women, particularly sex workers, before allegedly carrying out murders over an extended period while avoiding detection for more than a decade.
