Dalton Marshall, 19, of Vancouver, Washington, was found unconscious and bleeding in the street at North Bruce Avenue and Hudson Street in Portland in the early morning of November 12, 2015. First responders arrived after a call at about 2:04 a.m.; he was pronounced dead at the scene with at least one apparent gunshot wound. The Oregon State Medical Examiner ruled the death a homicide.

Investigators believe Marshall may have been socializing along North Interstate Avenue in the hours before he was found, but it remains unclear how he came to be at the location where his body was discovered. Police have not released any suspect information or a motive. Authorities noted a possible gang affiliation in the Vancouver area but have not determined whether that was related to the killing. A reward through Crime Stoppers of Oregon was offered for information leading to an arrest.

Anyone who knew Dalton, saw him in north Portland that night, or has information that could help the investigation is asked to come forward.
