Tyler Brown, a 46-year-old man with a lengthy criminal record, has been identified as the suspected gunman in Monday's shooting on Memorial Drive in Cambridge, Massachusetts.
According to a law enforcement source, Brown was charged with attempting to kill Boston police officers in 2020 after allegedly opening fire on law enforcement during an encounter.
Court records show Brown pleaded guilty to eight charges, including armed assault with intent to murder and attempted assault and battery with a firearm, stemming from the shooting at a Boston police officer.
In 2021, Brown was sentenced to five to six years in state prison, followed by probation, with the court also ordering him to undergo mental health evaluations and treatment.
On Monday, Boston police officers attempted to conduct a wellbeing check at Brown's home in Dorchester after his parole officer alerted authorities that he had allegedly made suicidal statements.
Brown was seen during a FaceTime call holding what appeared to be an assault-style rifle and allegedly threatened to use it, before opening fire on passing vehicles along Memorial Drive.
A Massachusetts State Police trooper shot Brown and took him into custody.
