Police used thermal imaging from a helicopter to monitor Dzhokhar Tsarnaev's movement inside of the boat he had been hiding in, when they apprehended him Friday night. Dzhokhar, who was bleeding profusely, remains prone on the floor of the boat for much of the video, as police use a robot to tear away the tarp covering the boat, as well as throw what appears to be flash-bang grenades at the boat.
The younger Tsarnaev brother is still in serious condition, and has not yet been interrogated.
"I, and I think all of the law enforcement professionals, are hoping for a host of reasons that the suspect survives, because we have a million questions, and those questions need to be answered," Governor Deval Patrick told reporters on Saturday.
Dzhokhar reportedly returned to his UMass-Dartmouth campus after the bombings, attending class and even going to a party on Wednesday evening. Dzhokhar left the campus after photos of him and his brother were released by the FBI on Thursday afternoon. "We made a joke like, that could be Dzhokar," Pamala Rolon, a classmate told the Boston Globe. "But then we thought it just couldn't be him. Dzhokar? Never."
The government is still deliberating on how to charge Dzhokhar, but a Justice Department official told CNN that "he will face federal terrorism charges and possibly state murder charges." Authorities are still trying to determine whether, when he is conscious, he will be read his Miranda warning, depending on whether the bombings can be considered a crime or an act of war.
