A gun-wielding career criminal opened fire at random cars driving down a Massachusetts roadway on Monday, leaving two men with life-threatening injuries before the maniac was shot by responding officers.
Gunman Tyler Brown allegedly fired 50 to 60 rounds indiscriminately from an assault-style rifle as he erratically walked down Memorial Drive in Cambridge around 1:20 p.m., Middlesex County District Attorney Marian Ryan said during a press conference.
At 1:06 p.m., Cambridge police received a 911 call from Boston police, who said an individual acting erratically and in possession of a rifle was in Cambridge, Ryan said.
Massachusetts State Police and Cambridge police arrived as Brown was actively firing down the road at stopped cars, authorities said.
