Overview
- Tyler E. Brown, 46, opened fire Monday on Cambridge’s Memorial Drive with an assault-style rifle, shooting two drivers who remain in critical condition.
- A Massachusetts State Police trooper and a former Marine licensed to carry confronted Brown and shot him, ending the attack within minutes.
- Authorities say he fired about 50 to 60 rounds and struck at least a dozen vehicles as drivers fled, and investigators report no known link between the suspect and the victims.
- Prosecutors have charged Brown with two counts of armed assault with intent to murder and other gun offenses, and his arraignment is on hold as he remains hospitalized in police custody.
- Court paperwork says Brown was released from a psychiatric hospital on Friday and, during a video call with his parole officer around noon Monday, waved a rifle and expressed suicidal intent.
