Michael Guy Johnston, 32, was last seen July 22, 1981, in Brigham City, Utah after spending the evening at a local bar with Debbie Griffiths. The two played pool and later went to Griffiths’ apartment, where they encountered Griffiths’ ex-husband, Rudy Matthew Rebeterano. Griffiths heard a violent-sounding confrontation between the men, then saw Rebeterano carrying a large white bundle that he loaded into the trunk of Johnston’s car and drove away.

Johnston’s car was later found abandoned nearby with bloodstains inside and around the trunk that matched his blood type. Johnston’s body was never recovered. Rebeterano was convicted of second-degree murder in the case; authorities continue to search for Johnston’s remains.

If anyone knew Michael, his movements that night, or has information about where his remains might be, please share what is known.
