INTERROGATION

Dzhokhar Silent After Miranda Rights

Sources say he was questioned for 16 hours before hearing them.

Boston bombing suspect Dzhokhar Tsarnaev was read his constitutional rights—but not until 16 hours into the investigation, two U.S. law-enforcement sources said Thursday. The officers, who were present during the private interrogation, said Dzhokhar immediately went silent upon hearing his Miranda rights. The 19-year-old suspect, they say, had already relinquished many details of the attack to police—including that his brother, Tamerlan Tsarnaev, had “recruited him” to assist in the attack and that they had been self-radicalized from the Internet. Late Wednesday officials announced that Dzhokhar was unarmed when police fired at a boat in which he was hiding.
