A Massachusetts Institute of Technology police officer who was killed overnight during a confrontation with the two Boston Marathon bombing suspects has been identified as Sean Collier. He was 26.
Shots rang out on the MIT campus around 10:20 p.m. Thursday. Soon after, Collier was found in his police car with multiple gunshot wounds, and was later pronounced dead at Massachusetts General Hospital, the Boston Globe reports.
On the MIT website, campus police chief John DiFava described Collier as a well-liked and dedicated officer who had become highly involved with MIT’s student population.
