BOSTON — The surviving Boston Marathon bombings suspect was released Friday from a civilian hospital and transferred to a federal medical detention center. The US Marshals Service said Dzhokhar Tsarnaev left Beth Israel Deaconess Medical Center overnight and was taken to the Federal Medical Center Devens about 65 km west of Boston. The facility, on the decommissioned Fort Devens US Army base, treats federal prisoners and detainees who require specialized long-term medical or mental health care. The 19-year-old Tsarnaev is recovering from a gunshot wound to the throat and other injuries suffered during his attempted getaway. The transfer comes a day after it was revealed that Tsarnaev and his brother had planned to go to New York's Times Square to blow up the rest of their explosives, authorities said. They portrayed a a chilling, spur-of-the-moment scheme that fell apart when the brothers realized the car they had hijacked was low on gas. New York City Police Commissioner Raymond Kelly said Dzhokhar Tsarnaev told interrogators from his hospital bed that he and his older brother had decided spontaneously last week to drive to New York and launch an attack. In their stolen sport utility vehicle they had five pipe bombs and a pressure-cooker explosive like the ones that blew up at the marathon, Kelly said. “New York City was next on their list of targets,” Mayor Michael Bloomberg said. Dzhokhar is charged with carrying out the Boston Marathon bombing that killed three people and wounded more than 260, and he could get the death penalty. Investigators and lawmakers briefed by the FBI have said that the Tsarnaev brothers — ethnic Chechens from Russia who had lived in the US for about a decade — were motivated by anger over the US wars in Iraq and Afghanistan. Based on the younger man's interrogation and other evidence, authorities have said it appears so far that the Muslim brothers were radicalized via jihadi material on the Internet instead of by any direct contact with terrorist organizations, but they have said it is still an open question. Dzhokhar was interrogated in his hospital room over a period of 16 hours without being read his constitutional rights. He immediately stopped talking after a magistrate judge and a representative from the US Attorney's office entered the room and advised him of his rights to keep quiet and seek a lawyer, according to a US law enforcement official and others briefed on the interrogation. — AP
