Terrence Rodger Demildenhall, a 22-year-old white man, was found dead before dawn on September 2, 1986, in his sleeping bag beside the west seawall of the Willamette River in Portland’s Waterfront Park, about a hundred yards north of the Morrison Bridge. He had been seen alive around 12:30 a.m., asleep in that same spot. When officers reached him later that morning he had been shot to death; the shooting occurred while he slept in the open.

Investigators later linked Demildenhall’s killing to a similar slaying months afterward. On February 27, 1987, 36-year-old Fred Edgi was found in his sleeping bag under the west side of the Burnside Bridge, shot in the head less than half a mile from Demildenhall’s scene. Authorities described striking parallels and said evidence connected the two murders, indicating a single offender targeting vulnerable people bedding down along the river. No arrests or publicly identified suspects have been announced and detectives continue to seek tips.

If anyone knew Terrence, Fred, or saw people sleeping along the waterfront that night, can you help investigators by coming forward?
