At 2;50 p.m. on Monday, hundreds of people formed a human chain, starting at the site where Sean Collier was killed and stretching down Vassar Street toward the MIT campus police building.

The human chain was to bring the MIT Community together during the moment of silence at 2:50 to remember Sean Collier, show support for the MIT Police officers as well as all the victims of the Boston Marathon Bombings.

MIT students, faculty, and staff all joined.

People raised their arms while observing a moment of silence and forming a human chain from a makeshift memorial for fallen MIT police officer Sean Collier to a campus police station.

“We will ask all at MIT who want to participate to make their way to various points on Vassar Street and hold hands, to remember Officer Collier, and to show our support to the MIT Police and come together as a community along the route that Officer Sean Collier drove many times. I think he would have liked this,” according to an email distributed on campus Monday.
