Following a weeklong criminal trial rife with racial and political overtones, a Baltimore teenager was found guilty Thursday of voluntary manslaughter in the deadly shooting of a baseball bat-wielding driver who approached youths washing windshields at a busy downtown intersection last summer. Throughout the trial, defense attorneys tried to assign responsibility to Timothy Reynolds, who armed himself with a metal bat and confronted the group of windshield washers near the city’s Inner Harbor during rush hour. Reynolds, 48, was shot five times, including three gunshot wounds to his back.
