Within hours, Tamerlan Tsarnaev would be killed in a shootout with police in Watertown, Mass., and Dzhokhar Tsarnaev would be on the run before being taken, seriously injured, into custody.
Law enforcement authorities said they recovered the backpack from a landfill in New Bedford, not far from the suspects’ apartment. Inside it were the fireworks, the jar of Vaseline, and a homework assignment sheet from one of Tsarnaev’s classes.
The court documents did not say what happened to the laptop.
After Wednesday's court hearing, Stahl said the allegation that his client recognized Tsarnaev as one of the bombers right away is in "dispute" and said "his first inkling came much later."
Likewise, he said, Kadyrbayev did not know the backpack's potential connection to the bombing. "He did not know that those items were involved in a bombing, or were evidence in a bombing, or had evidentiary value," he said.
Tazhayakov's attorney, Harlan Protass, said his client has "cooperated fully" with the authorities.
"My client ... feels horrible, and was shocked to hear that someone he knew at the University of Massachusetts Dartmouth was involved with the Boston Marathon bombing," he said.ALSO:
