MIT Dedicates New Memorial to Slain Boston Marathon Police Officer


Campus police officer Sean Collier, who was killed by Boston Marathon bombers Tamerlan and Dzhokhar Tsarnaev on April 18, 2013, was honored with a 190-ton memorial unveiled in Cambridge, MA, on Wednesday. It's the result of a collaboration between MIT architecture professor Meejin Yoon, structural engineering professor John Oschendorf, students, and a construction crew led by Collier's brother. Over 100 potential designs were submitted. The final design includes 32 pieces of polished granite from a New Hampshire quarry, forming five radial walls that resemble an open hand, to represent service and generosity. There's an open space in the center in the exact shape of a stone built by MIT's hiking group, the Outing Club, in tribute to Collier, an involved member. [MIT]
