Derrick Alexander Sellman

Deadly force

An off-duty corporal with Baltimore County Police with the surname Gonzalez shot and killed Derrick Sellman. Gonzalez was finishing his shift working as a security guard when another guard saw a black 2011 Chevrolet Suburban driving erratically near the mall's ShopRite grocery store. While Gonzalez was talking through the window to Sellman, Sellman began driving away and dragged Gonzalez, who was struck by a car traveling the opposite direction. Gonzalez shot Sellman once, and he crashed the Suburban.
