Vice President Joe Biden has told the parents of slain Massachusetts Institute of Technology police Officer Sean Collier that he hopes they find some solace in their extreme grief through a large memorial service in their son's honor.
Biden told thousands of students, faculty and staff, law enforcement officials from across the nation who had gathered Wednesday to pay respects at Briggs Field on campus that no child should predecease their parents.
School President L. Rafael Reif told those gathered that Collier not only had a job at MIT, but also had a life at MIT.
As many as 10,000 people were expected on campus for the memorial. They had to make their way through tight security, including metal detectors and bomb-sniffing dogs ahead of the service.
MIT Police Chief John DiFava and members of Collier's family also spoke at the service.
