PORTLAND, Ore. (KOIN) — A $2,500 reward is being offered for any information leading to an arrest in an unsolved Portland homicide case.

Thomas Richard Osborn was killed in a shooting in the Irvington neighborhood on Nov. 2, 2019. Six months later, no suspect has been found.

The 48-year-old Portland resident was found dead by police in the driver’s seat of a car on Northeast Broadway and Northeast 20st Avenue after police officers responded to a report of a shooting and someone injured in a vehicle around 2:16 a.m. that morning, according to authorities. The state’s medical examiner’s office determined Osborn died of multiple gunshot wounds.

Investigators later learned that Osborn was seen getting into a brief disagreement with an unidentified group of people at a nearby 7-Eleven on Northeast 21st and Broadway.
