THE BOSTON MARATHON bombing suspects intended to blow up their remaining explosives in New York’s Times Square, New York officials revealed today.

Police Commissioner Raymond Kelly said Dzhokhar Tsarnaev told interrogators from his hospital bed that he and his older brother had decided spontaneously on Thursday night, three days after the Boston attack, to go to New York to detonate their remaining explosives. That haul included a pressure-cooker bomb like the ones that blew up at the marathon and five pipe bombs.

The plan fell apart after the Tsarnaev brothers were intercepted by police in a stolen car and locked into a fierce gun battle that left Tamerlan Tsarnaev dead, Kelly said.

Dzhokhar, 19, is charged with carrying out the Boston Marathon bombing that killed three people and wounded more than 260. He could face the death penalty.

He was interrogated in his hospital room for 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 gave him his Miranda warning, according to a US law enforcement official and others briefed on the interrogation.
