The now infamous white hat and black jacket Dzhokhar Tsarnaev was wearing when he allegedly left a bomb on Boylston Street during the Boston Marathon was found in his University of Massachusetts Dartmouth dorm room.
The evidence recovered by federal agents was detailed in a 10-page criminal complaint that was unsealed Monday afternoon. Tsarnaev faced a federal magistrate judge Monday from his Beth Israel Deaconess Medical Center hospital bed. He is so far charged with use of a weapon of mass destruction and malicious destruction of property resulting in death.
According to the court clerk notes, the 19-year-old alleged bomber declined to answer bail questions during the appearance.
While the court documents said that Tsarnaev suffered gunshot wounds to his head, neck, legs and hand after an early Friday shootout in Watertown, court officials were "satisfied that the defendant is alert and able to respond to the charges."
Federal public defenders Miriam Conrad, Timothy Watkins and William Fick have been initially assigned to defend Tsarnaev. They did not immediately respond to a request for comment.
The complaint offers new details about the bombing one week ago that killed three people and injured nearly 180 others standing near the finish line of the Boston Marathon.
Federal Bureau of Investigation Special Agent Daniel Genck wrote in the complaint that he observed Tsarnaev and his brother, Tamerlan on surveillance images carrying backpacks along Boylston Street. Just before the second blast, Tsarnaev is seen walking "calmly but rapidly" away from the backpack about 10 seconds before it explodes.
Genck also wrote in the complaint that when Tsarnaev was finally captured after a manhunt and standoff Friday in Watertown, he was found to have credit cards and his UMass student identification card on him. Federal agents searched his dorm room and found a large pyrotechnic, a black jacket and white hat as well as BBs believed to be included in the bombs, the complaint said.
A probable cause hearing is scheduled for May 30.
