5. A Haunting Message
The “Lipstick Killer” was a woman named Frances Brown who, upon claiming her second victim, wrote this chilling message on the wall in lipstick. Detectives who found the victim’s body also found a bloody thumbprint on the doorknob, and the newspapers went to town on the message the perpetrator had left behind. Brown claimed one more person before being apprehended, a fate that she wanted if she really believed the writing on the wall. The assumption was that the guilty party was male, but it turns out the perpetrator was a 32-year-old woman.
