Adolfo de Jesús Constanzo became one of Mexico's most notorious serial killers after leading a violent criminal cult that combined ritualistic beliefs with narcotics trafficking during the 1980s. Operating primarily in Mexico City and Matamoros, Constanzo and his followers carried out numerous murders as part of ceremonies they believed would provide supernatural protection and success. The discovery of multiple victims at his ranch in 1989 exposed one of the most disturbing criminal conspiracies in Mexican history.

Aileen Wuornos was an American serial killer who murdered multiple men in Florida between 1989 and 1990. Operating primarily along highways, she targeted men she encountered while working as a sex worker. Her case gained widespread attention due to her background, her claims of self-defense, and the rarity of a female serial killer receiving the death penalty. Wuornos was convicted of multiple murders and executed in 2002.

Andrew Phillip Cunanan carried out a five-victim murder spree across four states between April and July 1997 that culminated in the fatal shooting of Italian fashion designer Gianni Versace outside his Miami Beach home. Beginning with the murder of his former friend Jeffrey Trail in Minnesota, Cunanan killed architect David Madson, wealthy Chicago developer Lee Miglin and New Jersey cemetery caretaker William Reese before targeting Versace. The nationwide manhunt that followed became one of the largest in FBI history. Eight days after killing Versace, Cunanan died by suicide aboard a houseboat in Miami Beach as law enforcement closed in.

Christopher Gregory Davis murdered his boyfriend, 56-year-old Barry Schmalbach, in Cape Coral, Florida, after Schmalbach planned to end their relationship in July 2023. Although Schmalbach's body has never been recovered, investigators built an extensive circumstantial case showing Davis using his boyfriend's financial accounts, purchasing items associated with concealing and disposing of a body, renting an isolated property under a false identity and attempting to dispose of tools. In June 2025, a Lee County jury convicted Davis of second-degree murder, tampering with evidence and eight identity-related offences. He was sentenced to life imprisonment plus 45 consecutive years.

Christopher Monks Jr. became the subject of a high-profile criminal case after conspiring to murder his adoptive parents in Kent, England, in 2009.

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.

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

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.

His crimes were uncovered only after human remains blocked drains at his apartment building, leading to one of Britain's most shocking homicide investigations.
