Overview
- The rampage, which unfolded Monday around 1:30 p.m. near River Street, left two male drivers in Boston hospitals with life-threatening injuries.
- Police identified the suspect as Tyler Brown, 46, of Boston, who was shot by a state trooper and an armed civilian and remains in custody in a hospital ICU.
- Middlesex DA Marian Ryan said Brown fired 50 to 60 rounds from an assault-style rifle, striking at least a dozen vehicles, and one victim was driving an MBTA The RIDE van.
- Boston police had alerted Cambridge at 1:06 p.m. about a person acting erratically and believed to be armed, and Ryan said charges will include two counts of armed assault with intent to murder.
- State and local investigators are collecting video and witness accounts, officials say there is no ongoing threat, and Brown’s probation or parole status is drawing scrutiny as the inquiry continues.
