CAMBRIDGE, Massachusetts — The Massachusetts Institute of Technology has dedicated a permanent memorial in honor of campus police Officer Sean Collier, who was slain by the Boston Marathon bombers.
Police Chief John DiFava said the memorial dedicated Wednesday is "overwhelming."
The memorial is at the site Collier was slain. It features five granite walls arranged in a radial pattern resembling the spread fingers of an open hand, connected by a vault in the center where "In the line of duty, Sean Collier April 18, 2013" is etched.
A temporary memorial has been at the site since October 2013.
Designer J. Meejin Yoon says the most important part of the memorial is "the space of remembrance where the walls form the vault." She calls it a place of "pause and reflection."
