In an interview from Russia, Tsarnaeva said Friday that she has never been linked to terrorism.
"It's all lies and hypocrisy," she said 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 theft of more than $1,624 worth of women's clothing from a Lord & Taylor department store in Natick 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 questioned both parents in Russia this week.
Late this week, Dzhohkar Tsarnaev 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, and 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.
Two college buddies of his — Azamat Tazhayakov and Dias Kadyrbayev — have been interviewed at length, twice, by FBI agents and have cooperated fully, said Kadyrbayev's lawyer, Robert Stahl, a former federal prosecutor.
