Tyler Brown has been identified as the suspected gunman in Monday’s shooting on Memorial Drive in Cambridge, Massachusetts.
Who is Tyler Brown and what is his criminal history?

According to a law enforcement source cited by Boston 25 News, Brown is a 46-year-old man with an extensive criminal record.
In 2020, he was charged with attempting to kill Boston police officers after allegedly opening fire on law enforcement during an encounter.
Court records show Brown later 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. The court also ordered him to undergo mental health evaluations and treatment.
At the time, then–Suffolk County District Attorney Rachael Rollins criticized the sentence as too lenient, saying she was “disappointed." She had sought a prison term of 10 to 12 years, followed by five years of probation.
