Neighbors are mourning the death of a 23-year-old man who was shot outside his Gresham condominium Sunday night.

Shane Michael Brumbaugh, 23, was working on his van in the driveway behind his home at the Tee Off Estates in the 1400 block of Northeast Paropa Court at about 6:45 p.m. when he was shot, neighbors said.

Brumbaugh was hit in the neck and chest but managed to run inside, where he collapsed at the top of the stairs. Meanwhile, his neighbor Ray, who declined to provide a last name, chased the gunman to a car parked around the corner on Northeast 16th Street. The car — which contained a driver, the gunman and a lookout — then sped off onto Northeast Kane Drive.

Ray then ran to the victim's home. With help from the victim's live-in girlfriend, they tried to perform CPR, but Brumbaugh died at the scene.

The East Multnomah County Major Crimes Team is investigating the shooting. Anyone with information should call the Gresham Police Department at 503-823-3333 or the tip line at 503-618-2719.
