Investigators have revealed that the Boston Marathon bombers, brothers Tamerlan and Dzhokhar Tsarnaev, originally from Chechnya, only had one real gun and one pellet gun as they fled the area. Collier was shot at point-blank range in the head as he sat in his patrol car.
On Wednesday Collier was laid to rest at a church in Stoneham, Massachusetts. A private funeral Mass was held for the officer on Tuesday.
Collier, 27, was remembered as a “curious and charismatic officer” who had wanted to be a policeman since he was 7 years old. He took an active role in campus life, said M.I.T.’s president, L. Rafael Reif, asking students about their studies and joining the outdoors club, whose conditioning workouts — climbing 21 flights of stairs — he performed in full uniform.
“In just 15 months, he built a life with us that was rich in friendship and shared adventure,” Dr. Reif said. “And he touched people across our community with his deep kindness and openhearted willingness to help, his humor and enthusiasm, his playful charm.”
