Born in the United States to Scottish parents, Peter Manuel returned to the UK at age 5. As a child, he was constantly in trouble, culminating in his first jail term (for sexual assault) at the age of just 16. He served another prison term in England (for attempted rape) before moving to Glasgow, Scotland, in 1953.
Over a two year period, from January 1956 and 1958, a series of particularly brutal murders claimed the lives of eight people in and around Glasgow. Two of the incidents involved triple homicides carried out by a home invader. In these instances the killer shot the family to death, then spent days living in their homes, eating their food, even feeding their pets, while the bodies still lay there.
The police meanwhile were stymied, in the main due to their refusal to admit that the killings were linked and that a serial killer was responsible. This would only come to light when Manuel was arrested, after banknotes stolen from one of the homes was linked to him.
Taken into custody, Manuel quickly confessed to the triple homicides, plus the rape / murders of two young women and the shooting of a cab driver in Newcastle, England. He later admitted to a total of 18 murders.
Peter Manuel was hanged at Barlinnie prison in Glasgow on July 11, 1958.
