Tyler Brown, 46, appeared via video from a hospital bed in Cambridge District Court on Thursday, entering not-guilty pleas to charges of armed assault with intent to murder and six other counts, including illegal possession of a firearm. Judge David Frank ordered Brown held without bail pending a detention hearing on May 21. Brown’s attorney, Carolyn McGowan, declined to address the charges outside of scheduling matters.
The pleas stem from a shooting Monday afternoon on a heavily traveled stretch of Memorial Drive along the Charles River. Middlesex Assistant District Attorney Nicole Allain said in court that Brown fired at least 70 rounds from an assault-style weapon, sending panicked drivers scrambling from their vehicles or hiding underneath them. One victim, shot in the back of the head, has been discharged from the hospital, while another remains hospitalized after being shot four times in the leg.
New details from the criminal complaint reveal a cascading crisis in the hour before the violence. Brown held a video conference with his parole officer while brandishing a gun and disclosed he had relapsed and wanted to end his life. The parole officer immediately contacted the Cambridge Police Department, which used phone records to locate Brown in the area.
Prosecutors detailed a lengthy criminal record going back to a 1994 armed robbery conviction in Michigan, followed by convictions for escape, drug offenses, and multiple gun-related crimes in Massachusetts. Most recently, in 2021, Brown was convicted of firing at officers. Meghan Kelly, a spokesperson for the Middlesex District Attorney’s Office, stated Brown was not licensed to carry a firearm.
The most scrutinized chapter of Brown’s history is his 2021 sentencing for the officer-involved shooting. Prosecutors argued then that Brown’s “level of brazen violence” warranted a minimum of 10 years in prison. Suffolk Superior Court Judge Janet Sanders instead imposed a sentence of five to six years followed by three years of probation, after receiving letters of support from Brown’s family and city officials convinced of his commitment to rehabilitation.
In imposing the lighter sentence, Judge Sanders acknowledged she was overriding the warnings of law enforcement. “When experienced officers, experienced probation officers tell me this guy is a danger to the community, I hear that,” the judge said at the time, according to an audio recording of the proceedings. “I can’t look into a crystal ball and figure out what is going to happen once you get out. But I do understand I am taking a risk here.”
The outcome has resurfaced criticism from police. The Boston Police Patrolmen’s Association described the situation as a “ball drop” in a social media statement. The renewed backlash underscores a persistent tension among lawmakers, mental health advocates, and law enforcement over how Massachusetts courts balance a defendant’s psychiatric history and potential for rehabilitation against the imperative of public safety.
Brown is due back in court for a bail hearing on May 21.
