Mike Riemer and Diana Robertson

Real Name: Michael Lloyd Riemer
Nicknames: Mike Riemer
Wanted For: Murder/Questioning
Missing Since: December 12, 1985


Details: In December 1985, 36-year-old trapper Mike Riemer took his girlfriend, Diana Robertson and their daughter, Crystal, into the woods near Tacoma, Washington to look for a Christmas tree. That afternoon, Crystal was later discovered wandering around a department store without her parents. She was later identified after her photo was placed in the newspaper and her maternal grandmother recognized her. Mike and Diana had vanished without a trace, and all Crystal could tell police is that "Mommy is in the trees". Two months later, Diana's body was found deep in the forest around Elbe, Washington. She had been stabbed seventeen times and had a tube sock tied around her neck and there was no sign of Mike. His truck, which was nearby, had blood stains on the front seat and note on the dashboard that read, "I love you, Diana." Although her mother believed that it was his handwriting, it could not be confirmed. Police believe he is responsible for her murder as well as a double one that occurred in the same woods four months earlier. A man named Stephen Harkins was found shot to death in his sleeping bag. His companion, Ruth Cooper, was found two months later. They were camping in the same area where Mike set his traps. Both Ruth and Diana had been killed with the tube sock tied in the same way. Police considered that an unknown serial killer had killed both couples and hid Mike's body or that Mike himself was the serial killer. He apparently had a history of domestic violence, which along with other evidence was enough for police to issue a warrant for his arrest. He is 6'0" and 180 pounds, has blue eyes and brown hair with a scar on his upper lip. He is a skilled outdoors man who may be living off the land.
Extra Notes: This case first aired on the September 6, 1989 episode.
Results: Unresolved. In March 2011, a skull found by hunters just one mile from where Diana's body was found was identified as Mike Riemer. His skull had a bullet hole in it which might have been the cause of his death, but this is unconfirmed. Most of his body is still undiscovered, possibly scattered by scavengers. Police have since ruled him out as a suspect in the double murder, and authorities now believe that an unknown serial killer may be responsible for the Harkins/Cooper and Robertson/Riemer murders. Mike's father, Lloyd Reimer, has since died in 1993 at the age of 85.
