Arturo Eduardo Hernandez, 21, was fatally shot in the early morning hours of July 10, 2016, after leaving a party on the 500 block of Willow Street in Walla Walla, Washington. Witnesses reported an argument as Hernandez walked away; he suffered a single gunshot wound, was taken first to a local hospital and then flown to a Seattle-area hospital, and died at about 9:00 p.m. that evening, according to the King County Medical Examiner’s office.

Walla Walla detectives processed the scene and interviewed numerous people who had been at the gathering. Investigators initially considered a gang-related motive but later ruled out gang affiliation for Hernandez. No suspect has been publicly identified and no arrests have been reported; the motive remains unknown.

If anyone was at that party or has information about what happened that night, please come forward to the Walla Walla Police Department.
