A 46-year-old Boston man with a violent history of targeting law enforcement is in custody after allegedly firing up to 60 rounds from an assault-style rifle during a terrifying daylight rampage on Memorial Drive, Cambridge, Massachusetts, on 11 May.
Tyler Brown, who was previously convicted of attempting to murder police officers, left two motorists in critical condition on Monday afternoon before being gunned down by a State Police trooper and a former Marine who stepped in to halt the carnage.
