On August 21, 1973, police followed up on a tip that a suspect matching the description of pedophile child killer Charlie Chop-off had been spotted. By the time it became clear that this was the wrong man, an angry mob gathered outside the police station. The unfortunate suspect had to leave the station dressed as a policeman for his own safety.
In the 1970s, a serial killer targeted San Francisco’s gay men. Nicknamed the Doodler because he sketched portraits of his victims to strike up conversation, this forgotten murderer was never caught, largely because those in the gay community refused to talk.
