He was later convicted of multiple murders and sentenced to more than 200 years in prison.

William Devon Howell became one of Connecticut's most infamous serial killers after murdering seven women between 2003 and 2005. Most of his victims were vulnerable women struggling with addiction or involved in sex work in the Hartford area. Howell concealed six of the victims in a wooded location later dubbed the "Garden of Graves," making him the most prolific serial killer in Connecticut's recorded history.

Robert Hansen became one of Alaska’s most infamous serial killers after abducting women, flying them into the wilderness and hunting them before murdering them. Nicknamed “The Butcher Baker” because he outwardly lived as a quiet family baker while secretly committing brutal murders, Hansen terrorized Anchorage and surrounding areas throughout the 1970s and early 1980s. The case shocked investigators because Hansen appeared to be an ordinary husband, business owner and outdoorsman while hiding a sadistic double life. Authorities later discovered he targeted vulnerable women, particularly sex workers and dancers, before using Alaska’s remote wilderness as a personal hunting ground. His crimes became one of the most disturbing serial murder cases in American history and inspired numerous books, documentaries and films.

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.

Richard Francis Cottingham became one of the most infamous serial killers in American history after murdering numerous women and girls in New York and New Jersey between 1967 and 1980. Known as the "Torso Killer" because several victims were dismembered, Cottingham targeted women he encountered in hotels, bars, and areas associated with sex work. Following his arrest in 1980, he was convicted of multiple murders and later confessed to additional killings, making him one of the most prolific identified serial killers in the northeastern United States.

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.

His crimes generated widespread fear, exposed major investigative failures, and permanently changed homicide investigations in the United Kingdom.

David Parker Ray became one of the most infamous serial offenders in American history after constructing a soundproof torture chamber inside a trailer on his property in Truth or Consequences, New Mexico.

His crimes remain among the most disturbing criminal investigations in modern American history.

The investigation exposed major policing failures and remains one of the largest serial murder cases in Canadian history.
