Boston Marathon Bombing Trial Begins with Jury Selection

Jury selection began Monday in the trial of Dzhokhar Tsarnaev, accused in the 2013 bombings that killed three people and wounded 264 at the end of the Boston Marathon.

Dressed in a dark pullover and light pants, Tsarnaev appeared in federal court, opposite a first group of 200 to 250 potential jurors as US District Judge George O'Toole briefly went over the charges against him.

Tsarnaev, a 21-year-old ethnic Chechen who is a naturalized U.S. citizen, could get the death penalty if convicted. He has pleaded not guilty to all 30 charges against him.

The large size of the jury pool, which has already been through an initial round of screening through surveys sent out by mail, reflects the intense interest in the case.

Tsarnaev's attorneys had sought to have the proceedings moved out of Boston. They argued it would be impossible to find an impartial local jury because of intense news coverage and the fact that thousands of people attended the race or hid in their homes during a day-long lockdown in the greater Boston area after the bombing.

Tsarnaev was arrested four days after the bombing. Prosecutors say he and Tamerlan Tsarnaev, his 26-year-old brother, later shot and killed a university police officer. The brother died after a wild gun battle with police.

The Tsarnaev brothers were Muslims whose family emigrated to the United States about a decade before the attack, settling in Cambridge, Massachusetts, just outside Boston. According to prosecutors, Dzhokhar Tsarnaev wrote messages inside of the hull of the drydocked boat where he was discovered hiding four days after the attack indicating the attack was politically motivated.

The messages included "the U.S. government is killing our innocent civilians" and "I can't stand to see such evil go unpunished," according to court papers.

Three people died in the bombing: restaurant manager Krystle Campbell, 29; graduate student Lingzi Lu, 23; and Martin Richard, 8. Massachusetts Institute of Technology police officer Sean Collier, 27, was fatally shot three days later.
