"Boston Plotters Said to Initially Target July 4 for Attack" by ERIC SCHMITT, MARK MAZZETTI, MICHAEL S. SCHMIDT, and SCOTT SHANE; New York Times 5/2/2013

Excerpt

The surviving suspect in the Boston Marathon bombings told F.B.I. interrogators that he and his brother considered suicide attacks and striking on the Fourth of July as they plotted their deadly assault, according to two law enforcement officials.

But the suspect,Dzhokhar Tsarnaev, 19, told investigators that he and his brother,Tamerlan, 26, who was killed in a shootout with the police, ultimately decided to use pressure-cooker bombs and other homemade explosive devices, the officials said.

The brothers finished building the bombs in Tamerlan’s apartment in Cambridge, Mass., faster than they had anticipated, and so decided to accelerate their attack to the Boston Marathon on April 15, Patriots’ Day in Massachusetts, according to the account that Dzhokhar provided to authorities.  They picked the finish line of the marathon after driving around the Boston area looking for alternative sites, according to this account.

In addition, Dzhokhar Tsarnaev has told authorities that he and his brother viewed the Internet sermons of Anwar al-Awlaki, a radical American cleric who moved to Yemen and was killed in September 2011 by an American drone strike.  There is no indication that the brothers communicated with Mr. Awlaki.

Mr. Tsarnaev made his admission on April 21 — two days after he was captured while hiding in a boat in a nearby backyard — to specially trained F.B.I. agents who had been waiting outside his hospital room for him to regain consciousness.

After he woke up, they questioned him, invoking what is known as the public safety exception to the Miranda Rule, a procedure authorized by a 1984 Supreme Court decision which in certain circumstances allows interrogation after an arrest without notifying a prisoner of the right to remain silent.

The new details of what Dzhokhar Tsarnaev has told authorities emerged as the F.B.I. moved forward on Thursday with trying to determine how the brothers were radicalized and the role that Tamerlan’s wife, Katherine Russell, may have played in the plot or in helping the brothers evade the authorities after the attacks.
