At the Massachusetts Institute of Technology, near Building 32 (Stata Center) at 10:48 p.m. EDT, a campus police officer was shot multiple times.The officer, 26-year-old Sean Collier, was taken to Massachusetts General Hospital in nearby downtown Boston, where he was pronounced dead. The shooting was believed to be perpetrated by the suspects of the Boston Marathon bombings that took place in Boston three days prior to this shooting. The two suspects are brothers Dzhokhar Tsarnaev and Tamerlan Tsarnaev.
About three hours after the MIT shooting, Tamerlan died in a gunfight with police in Watertown, Massachusetts. In that gunfight, another officer was shot and seriously wounded. Dzhokhar was arrested 18 hours afterward in Watertown, and was hospitalized in critical condition from a gunshot wound to the neck.
