Tsarnaev has not given investigators any substantive information since officials informed him of his constitutional rights prior to charging him with use of and conspiracy to use a weapon of mass destruction, the source said Friday. Dzhokhar Tsarnaev was moved from Beth Israel Deaconess Medical Center, where he has been held and interrogated since his capture last week, to the federal prison at Fort Devens, Mass., the Marshals Service said. Latest developments in the Boston bombings probe 
 
 Beth Israel is one of several hospitals that treated the more than 260 people injured in the Boston Marathon attack allegedly pulled off by Dzhokhar and his older brother Tamerlan. The surviving suspect in the Boston Marathon bombings has been moved from the hospital to a federal prison 40 miles away that provides specialized medical care, the government said Friday. The federal Bureau of Prisons hospital, located on the grounds of the former Fort Devens U.S. military base, is designed for patients requiring ongoing medical care, according to the facility's website. He also has injuries to the leg and hand, apparently from a firefight with police in suburban Watertown, Mass., on April 19 that played out about 12 hours before Tsarnaev was captured hiding in a boat parked in the driveway of a house. Authorities say an overnight shootout with police left him dead on April 19, 2013. Related stories

 Three days after that attack, and hours after authorities released images of two suspects, they "spontaneously" decided to go to New York's Times Square to blow up their six remaining explosives, Dzhokhar Tsarnaev told investigators.
– Boston is now rid of Dzhokhar Tsarnaev, who has been transferred to a federal prison medical facility about 40 miles west of the city. "Dzhokhar Tsarnaev has been transported from the Beth Israel Deaconess Medical Center and is now confined at the Bureau of Prisons facility FMC Devens at Ft. Devens, Massachusetts," says an official. The amount of time he spends at the local facility hinges on whether prosecutors decide to pursue execution, NBC News notes. Attorney General Eric Holder will ultimately make the call, but he likely won't do so for several months. Meanwhile, Tsarnaev's parents have left their home in Dagestan—but they're not headed to the US, at least for now. Instead, they're going elsewhere in Russia, CNN reports. Zubeidat Tsarnaeva cites her husband's health; she called him an ambulance yesterday, but gave no details on his condition. (Meanwhile, the Tsarnaevs' carjacking victim tells his story.)
