Patricia Doker, Jemima McDonald, and Helen Puttock were all raped and strangled to death with their stockings after visiting the Barrowland Ballroom in Glasgow. Puttock’s sister, Jean Puttock, told the police about the killer’s affinity for bible verses after sharing a taxi with the killer and her sister on the eve of her sister’s murder. This statement earned the serial killer the moniker Bible John. More than 1000 suspects were investigated but no arrests were made. The case remains unsolved.
