Dean Owen Tahtinen was 30 when he was found dead in his Portland, Oregon, apartment in the evening of January 6, 1997. His brother Sean had last spoken with him on January 3 and was due to take him to the airport on January 5 for a work trip to Arizona; when Dean missed the trip and could not be reached, concern led Sean to check the apartment in the 106th block of Northeast Wygant. An autopsy later determined Dean died of homicidal violence; investigators did not publicly release specific injuries.

Detectives established that Dean was last seen alive the evening of January 4, 1997, at CC Slaughters, a downtown Portland bar he frequented, and he was not observed leaving with anyone in particular. No suspects have been publicly identified and no arrests have been announced. A reward is being offered for information that could lead to an arrest in this active cold case.

If anyone knew Dean, saw him at CC Slaughters on January 4, 1997, or has information about his movements that week, please come forward.
