How much of those conversations will end up in court is unclear. The FBI normally tells suspects they have the right to remain silent before questioning them so all their statements can be used against them.
Under pressure from Congress, however, the Department of Justice has said investigators may wait until they have gathered intelligence about other threats before reading those rights in terrorism cases. The American Civil Liberties Union has expressed concern about that.
Regardless, investigators have found pieces of remote-control equipment among the debris and were analyzing them, officials said. One official described the detonator as “close-controlled,” meaning it had to be triggered within several blocks of the bombs.
They also 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, two U.S. officials said.
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.”
Dzhokhar’s public defender had no comment on the matter yesterday. His father has called him a “true angel,” and an aunt has insisted he’s not guilty.
