Boston Marathon bomber Dzhokhar Tsarnaev has been transferred to a maximum security prison in Colorado. Tsarnaev had previously been held at a prison facility in Devens, Massachusetts, near Boston.
Before hearing the formal reading of his death sentence, Dzhokhar Tsarnaev addressed the courtroom. "I am sorry for the lives that I have taken, for the suffering that I have caused you, for the irreparable damage," Interfax cited him as saying.
