(NBC News) Boston Marathon bomber Tamerlan Tsarnaev was buried outside of Worchester, Massachusetts Thursday.
The body had been held for more than a week because no nearby cemetery would accept the it.
Meanwhile, photos of the four who were killed in the bombing hung on Capitol Hill at the first Congressional hearing on the attack.
Former Senator Joe Lieberman said Homeland Security failed.
"I believe, that though it might not have been easy, it was possible to have prevented the terrorist attacks in Boston," Lieberman said.
The Los Angeles Times revealed a warning was made five days before the attack that the marathon finish line was vulnerable to a bombing by the Boston Regional Intelligence Center.
The report said the FBI identified no specific suspects.
