Summary

On December 12th, 1985, 21-year-old Diana Robertson and her boyfriend 36-year-old Mike Riemer of Puyallup, WA took their two-year-old daughter, Crystal, up to a forested area in the mountains near Tacoma. Crystal was found at a Kmart 30 miles away, and the mystery of what happened to Diana and Mike began.

Join Mike and Morf as they discuss Diana Robertson and Mike Riemer. Diana's body was found months later but that only intensified the mystery. A tube sock was found wrapped around her neck. Mike's remains were found 25 years later, but the discovery answered few questions.
