Keddie Murders

In 1981, 36-year-old Glenna Sharp was renting a cabin with her five of her children in Keddie, California. When her 14-year-old daughter returned to the cabin one morning after a sleepover, she found her mother, her brother and one of his friends were bludgeoned to death with a hammer and bound with medical tape. One of her sister, Tina Sharp, was missing, while her two other siblings were sleeping in the next room. The remains of the Tina were found 3 years later. The case still remains unsolved.
