There was a new twist in the accounts of how Dzhokhar Tsarnaev was captured last week.
Two U.S. officials say he was unarmed when police captured him hiding inside a boat covered by a tarp in a neighborhood backyard. Authorities originally said they had exchanged gunfire with him for more than one hour Friday evening before they were able to subdue him.
The U.S. officials, speaking on condition of anonymity because they were not authorized to discuss the ongoing investigation, said investigators recovered a 9 mm handgun believed to have been used by Tamerlan from the site of a Thursday night gunbattle that injured a Massachusetts Bay Transportation Authority officer. Dzhokhar was believed to have been shot before he escaped.
The officials told the AP that no gun was found in the boat. Boston police Commissioner Ed Davis said earlier that shots were fired from inside the boat.
Asked whether the suspect had a gun in the boat, Davis said, "I'm not going to talk about that."
Kurt Schwartz, director of the Massachusetts Emergency Management Agency, did respond to the report.
"Within half a mile of where this person was captured, a police officer was shot. And I know who shot him." Schwartz said. "And there were three bombs that went off, and I know where those bombs came from. ... To me, it does not change anything. This guy was captured alive and will survive. True or not true, it doesn't change anything for me."
At MIT, bagpipes wailed as students, faculty and staff members and throngs of law enforcement officials paid their respects to MIT police Officer Sean Collier, who was ambushed in his cruiser three days after the bombing.
The line of mourners stretched for a half-mile. They had to make their way through tight security, including metal detectors and bomb-sniffing dogs.
