On the evening of April 22, 2023, Shawn Jemtegaard, a 42-year-old White man from Lacey, Washington, was shot in a parking lot in the 2500 block of Marvin Road Northeast in the Hawks Prairie area and later died after emergency surgery. Police were dispatched shortly before 6:12 p.m. after reports of a dispute and a man with a gunshot wound. Jemtegaard was found with a dime-sized gunshot wound to his torso; a 13-year-old son in the passenger seat witnessed the shooting and a bystander applied pressure to the wound.

Officers arrested 48-year-old Aaron Patrick Costello at the scene; he told police the pistol, described as a .380 caliber, was on a vehicle floorboard and said he acted in self-defense after being pushed. Witnesses and Costello’s manager described a preceding verbal and physical altercation and a traffic dispute. Costello was booked on suspicion of second-degree murder and held on high bail while the autopsy was pending.

If anyone witnessed the incident or knew the victim or the driver involved, can you share what you saw that evening?
