CAMBRIDGE, Mass. (AP) -- Thousands of Massachusetts Institute of Technology students, faculty and staff as well as law enforcement officials from across the nation are expected to attend a memorial service for fallen campus police officer Sean Collier.
MIT officials say they are expecting as many as 10,000 people at Wednesday's service at Briggs Field.
Authorities think the 27-year-old Collier was shot and killed by the Boston Marathon bombing suspects last Thursday.
Collier had worked for the MIT police for a little over a year, but was already well-respected by his colleagues and superiors, and popular with students. He often went on hikes with the MIT student outing club.
Vice President Joe Biden, as well as MIT President L. Rafael Reif, police chief John DiFava and members of Collier's family are scheduled to speak.
