Family, friends and colleagues are paying their final respects to the Massachusetts Institute of Technology police officer who authorities say was killed by the Boston Marathon bombing suspects.

A private funeral Mass for Sean Collier is scheduled for Tuesday at St. Patrick's Church in Stoneham (STONE'-em).

A memorial service open to law enforcement and the MIT community only is scheduled for Wednesday on MIT's campus. Vice President Joe Biden is expected to attend.

The 27-year-old Collier was shot multiple times as he sat in his vehicle last Thursday.

He had worked for the MIT police for a little over a year and had been offered a job with the Somerville Police Department.

He was a Wilmington native and a graduate of Salem State University.

He is survived by his parents and five siblings.
