 The tube sock murders are believed to be the work of a serial killer who has never been caught. He took the lives of at least four people in Mineral Washington and possibly others too. In August of 1985, Stephen Harkins and Ruth Carper worked at a vocational school in Tacoma. When neither Stephen nor Ruth turned up for work the next day, they were reported as missing, two days after they were last seen alive. Stephen's missing body was found by hikers in his sleeping bag at a campsite. His lifeless dog was also found at the same campsite. Ruth's remains were found two months later, half a mile away. She had a tube sock around her neck. Months later, Mike Reimer, Diana Robertson, and their young daughter planned a camping trip. As the true crime story goes, on December 12th, the day the couple were last seen, their daughter was found abandoned at a Kmart parking lot. Mike and Diana were never seen again, and the killer has never been caught.
