BOSTON - The Massachusetts Institute of Technology police officer said to have been shot and killed by the Boston Marathon bombing suspects has been identified as 26-year-old Sean Collier.
The Middlesex district attorney's office says Collier was a Somerville resident who had worked at MIT since January 2012.
Before that, he was a civilian employee of the Somerville Police Department.
MIT Police Chief John DiFava says Collier was a dedicated officer who was liked by his colleagues and the MIT community.
Collier was found shot several times in his vehicle in Cambridge at about 10:30 p.m. ET Thursday.
He was pronounced dead at Massachusetts General Hospital.
Authorities say he was shot by the two suspects in Monday's marathon bombings.
One of the suspects is dead after a gun fight with police.
