Joseph B. Quinn, 34, was fatally shot in the early evening of February 6, 2022, at the Village Square Apartments on East Montgomery Avenue in Spokane Valley, Washington. Neighbors reported yelling and arguing before multiple gunshots; officers found Quinn near the courtyard pool with a gunshot wound to the chest. Life-saving efforts were unsuccessful and he was pronounced dead at the scene.

Investigators recovered four 9mm cartridge casings and searched the area with K-9 units and air support after witnesses described a skinny white male, about six feet tall in dark clothing, leaving the scene. A reward was offered for tips while detectives continued evidence collection and witness interviews.

On April 28, 2022, 29-year-old Shayne R. Galloway was arrested at a Days Inn in Airway Heights. Court documents say the shooting grew out of a personal dispute: Quinn allegedly assaulted his ex-girlfriend and stole her car, and Galloway had been staying with her and sent messages about confronting Quinn. Investigators allege another woman may have lured Quinn to the complex.
