Mental Profile - Psychopathy

Albert Fish became one of the most horrifying killers in American history after murdering children during the early 1900s and later sending grotesque letters to victims’ families. Known for extreme sadism, self-harm and cannibalistic behavior, Fish terrorized New York and surrounding states while hiding behind the appearance of a quiet elderly man. Often referred to as “The Gray Man,” “The Boogeyman” and “The Werewolf of Wysteria,” Fish shocked investigators and the public because of the disturbing nature of his crimes and psychological abnormalities. His case became one of the earliest high-profile examples of criminal profiling and remains one of the darkest child murder cases in American true crime history.

William George Bonin became one of America's most infamous serial killers after murdering at least 21 boys and young men across Southern California between 1979 and 1980. Known as the "Freeway Killer" or "Highway Killer," Bonin often worked with teenage accomplices to abduct victims before murdering them and abandoning their bodies near California freeways. His crimes generated widespread public fear and resulted in multiple convictions, death sentences, and life imprisonment for several accomplices.

Robert William Pickton became one of Canada's most infamous serial killers after murdering women from Vancouver's Downtown Eastside during the 1990s and early 2000s. Convicted of six murders but believed by investigators to have killed many more, Pickton targeted vulnerable women, many involved in sex work or struggling with addiction, before disposing of their remains on his rural pig farm in Port Coquitlam, British Columbia. The investigation exposed major policing failures and remains one of the largest serial murder cases in Canadian 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.

Arthur John Shawcross became one of America's most infamous serial killers after murdering 14 people in New York between 1972 and 1989. After serving a prison sentence for killing two children, Shawcross was released on parole and later went on to murder at least 12 women in the Rochester area. His crimes remained unsolved for several years before investigators linked him to the murders through surveillance, witness testimony, and forensic evidence. Shawcross was sentenced to 250 years in prison, where he remained until his death in 2008.

David Alan Gore was an American serial killer who, along with his cousin Fred Waterfield, committed at least six murders of women in and around Vero Beach, Florida, from 1981 to 1983. Known collectively as the "Killing Cousins," the pair exploited Gore's position as an auxiliary sheriff's deputy and his knowledge of local citrus groves to lure victims, often using a badge or vehicle to gain trust before subjecting them to sexual assault, torture, and murder.

Richard Beasley became known as the “Craigslist Serial Killer” after orchestrating a series of murders involving fake job advertisements posted online in Ohio during 2011. Prosecutors alleged Beasley used Craigslist employment listings to lure financially vulnerable men to isolated rural locations where they were robbed, shot, and buried in shallow graves. The case generated national attention because it exposed how online classified platforms could be exploited by violent offenders targeting strangers. Investigators later connected Beasley to multiple killings and attempted murders linked to the fake employment scheme. The horrifying combination of internet deception, execution-style murders, and burial sites hidden in wooded areas made the case one of the most infamous online predator serial killer investigations in modern American criminal history.

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.

His brief but deadly murder spree shocked Britain and remains one of the country's most disturbing examples of predatory serial homicide.
