BOSTON — Boston Marathon bombing suspect Dzhohkar Tsarnaev was moved from a hospital to a federal prison medical center while FBI agents shifted the focus of their investigation to how the deadly plot was pulled off and searched for evidence Friday in a landfill near the college he attended.
Tsarnaev, 19, was taken from Beth Israel Deaconess Medical Center, where he was recovering from a throat wound and other injuries suffered during an attempt to elude police last week, and he was transferred to the Federal Medical Center Devens, about 40 miles from Boston, the U.S. Marshals Service said. The facility, at a former Army base, treats federal prisoners.
"It's where he should be; he doesn't need to be here anymore," said Beth Israel patient Linda Zamansky, who thought his absence could reduce stress on bombing victims who have been recovering at the hospital under tight security.
The FBI's investigation of the April 15 bombing has turned from identification and apprehension of suspects to piecing together details of the plot, including how long the planning took, how it was carried out and whether anyone else knew or was involved.
A federal law enforcement official not authorized to speak on the record about the investigation told The Associated Press on the condition of anonymity on Friday that the FBI was gathering evidence regarding "everything imaginable."
FBI agents picked through a landfill near the University of Massachusetts Dartmouth, where Tsarnaev was a sophomore. FBI spokesman Jim Martin would not say what investigators were looking for.
An aerial photo in Friday's Boston Globe showed a line of more than 20 investigators, all dressed in white overalls and yellow boots, picking over the garbage with shovels or rakes.
Investigators also have continued to interview people who were close to Tsarnaev, including two young men from Kazakhstan who were students with him at UMass Dartmouth.
