MIT is today commemorating the life of fallen police officer Sean Collier, who was shot and killed in the line of duty Thursday night, with a memorial service at Briggs Field. Vice President Joe Biden will be speaking, alongside MIT President Rafael Reif, MIT Police Chief John DiFava and a member of the Collier family. With thousands of law enforcement agents expected to come in from all corners of the country, and James Taylor performing, the actual service is not open to the general public. MIT has provided a live webcast, however, which will begin at approximately 11:50 a.m., along with the live stream you’ll see by CBS Boston embedded below.

Twenty-six-year-old Collier is reported to have been shot by one or both of the Boston Marathon bombing suspects—one of whom is dead and the other in custody.

On Monday at 2:50 p.m., hundreds of MIT community members started linking arms to form a chain outside of the Institute’s Stata Center where Collier was shot. Together, they observed a national moment of silence on the one-week anniversary of the marathon bombings.

They come together again today to remember the life of a young Somerville man described by his peers as “a friendly and down-to-earth kind of guy that you would want to be friends with.”

“Sean was one of these guys who really looked at police work as a calling,” said DiFava to MIT News. “He was born to be a police officer.”

DiFava and MIT Police have created a website where people can offer their condolences. The Institute has also announced they are establishing a Sean A. Collier Memorial Fund. The fund will support a “Collier Medal,” which will be awarded “to individuals who demonstrate Collier’s values.” Per request of Collier’s family, memorial gifts can be made to The Jimmy Fund, an organization Collier was a longtime supporter of.
