Overview
- Tyler E. Brown, 46, entered not guilty pleas via video Thursday from a hospital bed and remains in custody pending a May 21 hearing.
- He faces eight counts that include armed assault with intent to murder and firearm offenses, following prior violent convictions and a recent psychiatric discharge.
- Prosecutors say he opened fire with an assault-style rifle on Memorial Drive on Monday, wounding two drivers before a state trooper and an armed civilian shot and disabled him.
- One victim who was struck in the back of the head has been released, while another who was shot multiple times in a leg remains hospitalized.
- About an hour before the gunfire, his parole officer reported a FaceTime call where Brown displayed a rifle, said he had relapsed and wanted to end his life, and police then pinged his phone to locate him in Cambridge.
