On March 21, 2009, Officer John Raymond Hege, 41, an Oakland Police Department officer of ten years and a former high school teacher, was critically wounded during a traffic stop at 74th Avenue and MacArthur Boulevard when the driver opened fire. Sergeant Mark Dunakin was killed at the scene; despite bystander CPR and emergency care, Hege died a few days later.

The shooter, a parolee with a documented violent history and a no-bail parole warrant, fled on foot and was located later in a barricade at an apartment building on 74th Avenue. During the SWAT approach the suspect again opened fire, killing Sergeant Ervin Romans and Sergeant Daniel Sakai and wounding another officer; the suspect was killed when the SWAT team returned fire.

The community marked the officers with memorials including renaming the Keller Avenue Bridge over I-580 and a memorial backstop at Hampton Field for Officer Hege. If anyone knew Officer Hege or has information about the traffic-stop shooting, please share what you can.
