Harold Treadwell, 71, was shot while driving in Phoenix, Arizona, on July 28, 2019. The shooting occurred just after midnight on what had been his 52nd wedding anniversary; he had been on the phone with his wife, Frances, moments earlier to wish her a happy anniversary. One bullet struck Treadwell, causing him to lose control of the vehicle, cross a median, and crash. Emergency crews responded but he died from the gunshot wound.

Phoenix Police opened a homicide investigation and asked the public for help identifying the shooter, but no suspect was immediately identified or taken into custody. Investigators said they did not know whether Treadwell was specifically targeted or the victim of a random act. The case has since gone cold with no publicly announced arrests and the person or persons responsible remain unknown.

If anyone witnessed the shooting, the crash, or saw anything suspicious that night, please share information with the Phoenix Police Department.
