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.

Jim Jones was an American cult leader and founder of the Peoples Temple, best known for orchestrating the mass murder-suicide in Jonestown, Guyana, in 1978.

Jones’ leadership became increasingly authoritarian and paranoid, culminating in the deaths of over 900 people, including children, after he directed followers to consume a poisoned drink. The incident remains one of the largest mass deaths in modern history and cemented Jones as one of the most infamous cult leaders of all time.
