Joseph Anthony "Joey" Carl (5539)

8/5/2010: Keast helped break up a party and outdoor bonfire, during which Carl's blood-alcohol level tested well above the legal limit to drive. Keast drove Carl home and left him in his father's care. Later that evening, Keast was called back to Carl's house after reports of window-breaking and yelling. When Keast arrived, Carl emerged from between cars parked on the street and began smashing the windshield of his squad car with a baseball bat. Keast attempted to move his squad car away from Carl, but as he backed up, Carl ran after him, bat raised. He smashed the driver-side window, ignoring Keast's orders to put the bat down. Keast fired once, killing Carl.
