Cambridge Memorial Drive shooting linked to man released from psychiatric care days earlier

A Cambridge gunman, Tyler E. Brown, who was released from McLean psychiatric hospital three days before the Memorial Drive attack, allegedly fired at least 60 rounds, injuring two people seriously after a parole officer warned he was at risk of violence. Brown, with a history of violence and prior prison sentences, faces armed assault with intent to murder, carrying a firearm without a license, and possessing a large-capacity firearm. He was halted by a state police trooper and an ex-Marine with a handgun; a public defender is listed for Brown as the investigation continues.
