Roystrom Roy Evalt, a 41-year-old Caucasian man, was found dead inside his 1969 brown Chevrolet Stepvan in a gravel parking area off Northeast Marine Drive in Portland, Oregon. Police were called to the 10,000 block on November 13, 1985, after a report of a possible deceased person in a parked vehicle. An autopsy determined he died of apparent stab wounds, and investigators narrowed the time of the murder to sometime between Tuesday, November 12, and Wednesday, November 13.

Mr. Evalt was described as semi-transient and had converted his van into a living space. Neighbors and acquaintances said his van had been parked in that location for weeks or even months before his death, and he was known to be very trusting and somewhat naïve. No suspects have been publicly identified and no arrests have been made; the Portland Police Bureau still lists the case among its unsolved homicides.

Are there details about Mr. Evalt’s routines, acquaintances, or anyone seen near the van in November 1985 that could help investigators?
