Mark Edward Doe, 52, was shot and killed after intervening in an attempted robbery in a downtown Tucson parking garage on Congress Street on April 25, 2021. According to reports, Doe confronted two young men who had been attempting to rob people and had carjacked a white Nissan pickup. As the suspects tried to flee after colliding with other vehicles, a group including Doe blocked the garage exit. During that confrontation one of the suspects fired a handgun, striking Doe; he was pronounced dead at the scene.

Police located the stolen pickup later that day and pursued it; shots were reportedly fired at officers before the truck was abandoned and a suspect fled on foot into an apartment complex. Investigators identified two suspects and arrested 21-year-old Luis Alberto Garcia the next day and 19-year-old Alexis Enrique Diaz a few days later. Both men were charged in connection with the robbery and Doe’s death.

Doe’s family remembered him for his love of life, his faith, and his optimistic outlook. Does anyone have information about the confrontation in the garage or the moments before the shooting?
