On the night of August 28, 1993, a gathering of Vietnamese youths on the 500 block of NE 80th in Portland was interrupted by gunfire at about 10:30 p.m. A red van, later identified as a 1979 Chevrolet with a yellow stripe, drove by and a passenger opened fire on a group standing outside. Nineteen-year-old Tien Hoang Truong, a Vietnamese male from Seattle, was struck and died at the scene.

Witnesses described the shooter as a Vietnamese man about 5 feet 3 inches tall, roughly 140 pounds, with black hair. Reports say Truong was affiliated with a Vietnamese gang in Seattle that had ties to a Portland gang and that the shooting is believed to be connected to those affiliations.

Anyone with information about that night, the red 1979 Chevrolet van with a yellow stripe, or the people involved is asked to contact the Portland Police Bureau Cold Case Homicide Unit or Crime Stoppers of Oregon.
