Harry Thalman, 52, was found dead in his ransacked apartment at the Wimbledon Square complex on Southeast 28th Avenue in Portland on July 11, 1990, after neighbors reported a strong odor and a maintenance supervisor checked the unit. An autopsy showed he had been killed by multiple stab wounds sometime before discovery. Thalman, a retired jeweler, had last been seen the evening of July 8 around 7 p.m. Investigators reported jewelry was missing and his 1987 gray-and-silver Cadillac DeVille was gone when the scene was inventoried.

Detectives noted Thalman often brought strangers and unhoused men back to his residence, a detail that expanded the pool of potential leads. The Portland Police Bureau later appealed for tips and offered a Crime Stoppers reward for information leading to an arrest, but no arrest or confirmed suspect has been announced and the case remains open as a cold case. If anyone knew Harry, saw his Cadillac after July 8, 1990, or has information about people he brought home, please come forward.
