Penny Krajeski was found murdered in her Chicago apartment in July of 1984. She had been living there alone after recently being emancipated from her family. Her body remained inside the apartment for days before police discovered it.

Investigators reported no signs of forced entry, though there were signs of a struggle inside the unit. No solid leads or arrests have been reported in the case; Penny’s sisters Nancy and Paula continue to search for information and say they are still grieving decades later.

If anyone remembers Penny, her apartment, or unusual activity in that building in July 1984, please come forward with information that could help her family and investigators.
