Gunman Opens Fire on Memorial Drive in Cambridge, Injuring Two

On Monday afternoon, Tyler Brown, 46, of Boston, allegedly opened fire with an assault-style rifle on Memorial Drive in Cambridge, Massachusetts, injuring two drivers and damaging multiple vehicles. The incident occurred near the Charles River, a popular area for pedestrians and cyclists.

According to Middlesex District Attorney Marian Ryan, Brown fired over 60 rounds, striking at least a dozen vehicles, including a Massachusetts State Police cruiser. Two male drivers sustained life-threatening injuries and were transported to Boston hospitals. The victims were not known to Brown.

The situation ended when a State Police trooper and a civilian, identified as a former Marine licensed to carry a firearm, confronted Brown. Both fired their weapons, striking Brown multiple times in the extremities. He was then taken into custody and is currently hospitalized.

Brown has a history of violent offenses. In 2020, he was convicted of firing at Boston Police officers and pleaded guilty to multiple charges, including armed assault with intent to murder. He was sentenced to 5-6 years in state prison, followed by probation, and was ordered to undergo mental health evaluations and treatment. At the time, then-Suffolk County District Attorney Rachael Rollins expressed disappointment with the sentence, stating, "I strongly believe that the sentence we proposed - 10 to 12 years followed by five years of probation - was appropriate for the level of brazen violence committed."

Prior to the shooting, Boston Police had issued an officer safety bulletin regarding Brown. His parole officer reported that he had made suicidal statements and was seen on a FaceTime video with an assault rifle, stating he would use it. The bulletin indicated that his phone was pinging in Cambridge.

The investigation is ongoing, and authorities are urging anyone with information or video footage from the incident to contact Massachusetts State Police Detectives at 781-897-6600.
