Biden to attend service for slain MIT police officer

Vice President Joe Biden and his wife, Jill Biden, will travel to Cambridge, Mass., on Wednesday to attend the memorial service for an MIT police officer allegedly killed by the suspects in the Boston Marathon bombings.

A White House official said the Bidens will attend the ceremony for Sean Collier, 26.

The noon event will be open to the MIT community and law-enforcement officers from around the country, the institution announced. It is expected to attract 10,000 attendees.

In his remarks after the manhunt for the suspects ended on Friday, Obama publicly sent prayers to Collier's family.

"He was just 26 years old. And as his family has said, he died bravely in the line of duty, doing what he committed his life to doing—serving and protecting others. So we're grateful to him," the president said.
