The suspect in the May 11 gun battle on Cambridge’s Memorial Drive is expected to be arraigned Thursday in Middlesex Superior Court in Woburn, officials said.
Tyler Brown, 47 of Boston, has been indicted on additional charges that will be heard, said Middlesex district attorney Marian Ryan, state police colonel Geoffrey Noble and acting Cambridge police commissioner Pauline Wells on Wednesday.
In that gun battle, a parolee in emotional distress brought an illegally obtained AK-47 assault rifle to the heavily populated area of 808 and 812 Memorial Drive in the Riverside neighborhood, between River Street and Pleasant Street Extension, officials said. He fired 50 to 60 rounds before being felled by a State Police trooper and an armed ex-Marine caught in the attack.
Two people were wounded before the shooter was taken down, and Brown recovered from gunshot wounds of his own.
Brown faces six counts of armed assault to murder; assault and battery with a dangerous weapon causing serious bodily injury; two counts of assault and battery by discharging a firearm; four counts of attempted assault and battery by discharging a firearm; six counts of assault and battery with a dangerous weapon; four counts of assault with a dangerous weapon on a person over 60; seven counts of malicious damage to a motor vehicle; two counts of intentional reckless discharge of a firearm; possession of a firearm after being convicted of a felony; two counts of wanton destruction of property over $1,200; three counts of wanton destruction of property under $1,200; carrying a firearm without a license; two counts of possession of ammunition; and two counts of possession of a large capacity magazine.
“It is public information that this individual was actually in a very high-quality reentry program, then fell out of it,” city manager Yi-An Huang said at a May community meeting about the attack. “As recently as Nov. 5, he was on stage in a button-down shirt in front of a room of people and speaking about his journey reentering society and doing well. I don’t know what happened between Nov. 5 and what we saw last week.”
State representative Mike Connolly added at the time that “on multiple occasions” the suspect has reached out for mental health care, and found it “impossible to access at different points in time.” Funding mental health care is vital, and Cambridge is in a better position than many communities – various mental health resources were mentioned and offering during the meeting – but it is increasingly under threat in federal budgeting, he said.
The prosecutor assigned to the case is Nicole Allain.
