A 46-year-old man is in custody after opening fire with an assault-style rifle on Memorial Drive in Cambridge, Massachusetts, on Monday afternoon. The suspect, identified as Tyler Brown, was shot and wounded by a responding Massachusetts State Police trooper and a civilian.
The incident occurred around 1:30 p.m. Between River Street and Pleasant Street Extension. Two men in separate vehicles sustained life-threatening injuries and are currently being treated at Boston hospitals.
Middlesex District Attorney Marian Ryan described the scene as an “active shooter situation,” noting that Brown walked down the middle of the road firing in an “erratic fashion.” According to Ryan, 50-60 rounds were discharged, striking at least a dozen vehicles, including a State Police cruiser.
The Response and Apprehension
As bystanders fled their vehicles, the trooper and the former Marine engaged the suspect. Both fired their weapons, striking Brown multiple times in the extremities.
Troopers provided immediate first aid to Brown and the two victims before they were transported to hospitals. Brown is currently being treated in an intensive care unit.
District Attorney Ryan stated that the incident lasted only minutes due to the actions of the trooper and the civilian. She emphasized that the weapon used had the capacity to strike people on the other side of the nearby Charles River.
Timeline of Events
The situation began earlier Monday morning when a photo of Brown was included in an officer safety bulletin. At approximately 12:30 p.m., police attempted a well-being check at Brown’s Dorchester home.
This check followed a report from Brown’s parole officer, who stated that the man had made a suicidal statement. Shortly after 1 p.m., Cambridge Police were notified by Boston Police that Brown was believed to be in the area with a rifle.
Impact and Legal Proceedings
Witnesses described a scene of chaos, with some drivers ducking behind dashboards and others fleeing through bushes. One woman in a school van, who was on her way to pick up children with special needs, reported running for her life after hearing numerous shots.
Brown now faces several charges, including two counts of armed assault with intent to murder. It remains unclear when he will be arraigned.
Massachusetts Governor Maura Healey confirmed she is monitoring the investigation. While she stated there is no ongoing threat to the public, she encouraged commuters to avoid the area as police tape remains in place.
Investigators do not believe there was any prior link between Brown and the individuals in the vehicles he targeted. Hundreds of witnesses are expected to be interviewed over the coming days.
What May Happen Next
Authorities may release further details regarding the suspect’s mental state following the review of witness interviews. Legal proceedings could be delayed until Brown is stabilized and cleared for medical release from the intensive care unit.
The Massachusetts State Police may also release further evidence if additional witness videos are submitted to the investigation.
