Boston bombing suspect Dzhokhar Tsarnaev has been moved from a hospital to a prison medical center in Massachusetts, a US marshal's spokesman told CNN Friday.
Tsarnaev was sent to the Federal Medical Center Devens, spokesman Drew Wade said.
The facility is about 40 miles (65 kilometers) northwest of the Boston-area hospital where Tsarnaev has been convalescing since he was found critically wounded in a boat in a massive police manhunt, days after the bombing which killed three and wounded 264.
The 19-year-old ethnic Chechen has been charged with using a weapon of mass destruction and could face the death penalty if convicted in US federal court.
His older brother, Tamarlan Tsarnaev 26, also accused of participating in the twin bombing, was killed in an explosive shootout as the two tried to evade police in a stolen car.
