William Robert Decker II, 44, was found dead from a single gunshot wound to the forehead in his Portland apartment in the early hours of April 22, 2023. North Precinct officers responded to a 2:16 a.m. shooting call in the 6700 block of Northeast Killingsworth Street in the Cully Neighborhood and discovered Decker deceased at the scene. The Medical Examiner ruled the death a homicide by gunshot wound.

Investigators identified Decker’s wife, 40-year-old Mariah Cole (also using the last name Decker), as a suspect. Cole was arrested and booked into the Multnomah County Detention Center on charges including Murder in the Second Degree, Unlawful Use of a Weapon, and Felon in Possession of a Firearm. Court documents say Cole first told investigators the shooting was accidental, claiming she reached for a bag of chips in a cupboard, found a gun, and it discharged. Detectives noted inconsistencies between her account and the scene — Decker was found lying on his back with a gunshot to the forehead while Cole had said he was sitting cross-legged — and reported that Decker had told someone a week earlier he feared his spouse might harm him.

Did anyone in the Cully Neighborhood see or hear anything that night, or know more about the relationship dynamics in the days before April 22?
