Search begins for Boston jury to try marathon bombing suspect

BOSTON (AP) - His accusers brandish a confession scribbled inside a boat during an intensive manhunt and a video they say shows him placing a backpack with a bomb a few feet from a little boy who died when it exploded seconds later.

His defenders bank on the story of a difficult childhood in a former Soviet republic and his radicalization at the hands of an influential older brother who could have pressured him into participating in the deadly attack.

Jury selection for the trial of Dzhokhar Tsarnaev, accused in the Boston Marathon attacks, begins Monday. Those chosen from a pool of about 1,200 will decide whether Tsarnaev planned and carried out the twin bombings that killed three people and injured more than 260 near the finish line of the race on April 15, 2013. If they find him guilty, they will decide whether he should be put to death.

It's perhaps the most closely watched federal death penalty case since Timothy McVeigh was convicted and executed for the 1995 Oklahoma City bombing. Tsarnaev's lawyers tried in vain for months to get the trial moved, arguing the Boston jury pool was tainted because of the number of locals with connections to the race and drawing parallels to the McVeigh case, which was moved to Denver for similar reasons. But U.S. District Judge George O'Toole Jr. has been unmoved.

Jury selection alone is expected to take several weeks because of extensive media coverage and the thousands of runners, spectators and others in the area personally affected by the bombings. The process also could be slowed if potential jurors express objections to the death penalty.

Some legal observers say Tsarnaev's lawyers - facing powerful evidence against him - will probably focus their energies on the penalty phase, when they could present mitigating evidence to spare his life. He has a strong team behind him. Attorney Judy Clarke touts a strong record of helping her high-profile clients avoid the death penalty, including Ted Kaczynski, the Unabomber; Olympic Park bomber Eric Rudolph; and Jared Loughner, who killed six people and wounded former U.S. Rep. Gabrielle Giffords.

Tsarnaev's lawyers are likely to narrow in on motive and any pressure exerted on him, said Dan Collins, a former assistant U.S. attorney in Chicago who has investigated U.S. ties to terrorism.

"I think his mitigation will be in part paying close attention to what his explanation is and what circumstances beyond his control ... caused him to do this," Collins said.

Prosecutors say 21-year-old Dzhokhar and his brother, Tamerlan Tsarnaev - ethnic Chechens who had lived in the United States for about a decade - carried out the bombings as retaliation for U.S. actions in Muslim countries. They are also accused of killing Massachusetts Institute of Technology police officer Sean Collier. Tamerlan, 26, died after a firefight with police several days after the bombings.

Dzhokhar was captured later that day, wounded and bloodied, hiding inside a boat stored in a suburban yard. Prosecutors said he described a motive in a note written in the boat: "The U.S. Government is killing our innocent civilians" and "We Muslims are one body, you hurt one you hurt us all."

Tsarnaev's lawyers may lay the groundwork for some kind of mental health explanation, said Christopher Dearborn, a professor at Suffolk University Law School.
