BOSTON - Boston Marathon bombing suspect Dzhokhar Tsarnaev was moved from a hospital to a federal prison medical center, while FBI agents searched for evidence Friday in a landfill near the college he was attending.
Tsarnaev, 19, was taken from Beth Israel Deaconess Medical Center, where he was recovering from a gunshot wound to the throat and other injuries suffered during a getaway attempt. 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.
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.
Meanwhile, the bombing suspects' mother had been added to a federal terrorism database about 18 months before the deadly attack - a disclosure that deepens the mystery around the Tsarnaev family and marks the first time American authorities have acknowledged that Zubeidat Tsarnaeva was under investigation before the tragedy, the Associated Press reported, citing unnamed U.S. officials.
The news is certain to fuel questions about whether the Obama administration missed opportunities to thwart the April 15 bombing that killed three people and wounded more than 260.
Tsarnaev is charged with joining with his older brother, now dead, in setting off the shrapnel-packed pressure-cooker bombs. The brothers are ethnic Chechens from Russia who came to the United States about a decade ago with their parents.
Two government officials, speaking to the Associated Press on condition of anonymity because they were not authorized to speak publicly about the investigation, said the CIA had Zubeidat Tsarnaeva's name added to the terror database along with that of her son Tamerlan Tsarnaev after Russia contacted the agency in 2011 with concerns that the two were religious militants.
About six months earlier, the FBI investigated mother and son, also at Russia's request, one of the officials said. The FBI found no ties to terrorism. Previously U.S. officials had said only that the FBI investigated Tamerlan.
In an interview from Russia, Tsarnaeva said Friday that she has never been linked to terrorism.
"It's all lies and hypocrisy," she told the Associated Press from Dagestan. "I'm sick and tired of all this nonsense that they make up about me and my children. People know me as a regular person, and I've never been mixed up in any criminal intentions, especially any linked to terrorism."
Tsarnaeva faces shoplifting charges in the U.S. over the alleged theft of more than $1,624 worth of women's clothing from a Lord & Taylor department store in Natick, Mass., in 2012.
Earlier this week, she said she has been assured by lawyers that she would not be arrested if she traveled to the U.S., but she said she was still deciding whether to go. The suspects' father, Anzor Tsarnaev, said that he would leave Russia soon for the United States to visit one son and lay the other to rest.
A team of investigators from the U.S. Embassy in Moscow has questioned both parents in Russia this week, spending many hours with the mother in particular over two days.
