Gunman struck two drivers, officials say

Key Points:

• Tyler Brown, 46, identified as the alleged gunman who shot two men with life-threatening injuries and was himself shot by police and a civilian during a shooting spree in Cambridge near Harvard and MIT campuses.
• Brown, previously involved in a 2020 shooting targeting Boston police officers, was armed with an assault-style rifle and fired erratically at vehicles on Memorial Drive before being stopped by law enforcement and a former Marine civilian.
• Brown is currently in intensive care and faces charges including two counts of armed assault with intent to murder and firearms offenses; he was on probation after release from prison for the 2020 incident.
• The rapid response by police and the armed civilian prevented further casualties, with authorities commending their quick and selfless actions amid a chaotic scene causing panic among motorists and pedestrians.
• Investigators are conducting extensive interviews and evidence review at the scene, which was sealed off for hours, causing significant disruption in the busy university area before reopening Memorial Drive late Monday night.
