Before this tragic incident, Boston Police had warned Cambridge officials that Brown might be in the area and in possession of a rifle.

Approximately an hour before the shooting, at 12:30 a.m., police officers attempted to conduct a welfare check at his home in Dorchester after his parole officer reported a suicidal statement from Brown.

Following the incident, officers at the scene immediately administered first aid to Brown and the two victims before they were rushed to a hospital in Boston.
Rapid Response and Arrest of the Shooter
Cambridge Police received a 911 call from Boston Police regarding Brown, who was believed to be in possession of a rifle, in the area.
When Massachusetts State Police arrived on the scene, they immediately encountered an active shooter situation.
In attempting to subdue the shooter, Brown was shot by a Massachusetts State Police officer and a civilian, a former Marine with a permit to carry a firearm.
