Tsarnaev looked down at the floor as he walked in to the jury assembly room and later nodded at a group
of about 200 citizens from eastern Massachusetts who were called for jury duty at the federal courthouse
in Boston.

The man accused of carrying out the deadly 2013 bombings silently drummed his fingers on the defense
table and looked at the judge as the potential jurors looked intently at him.

Tsarnaev, 21, faces possible execution if convicted in the attack that killed three people and wounded
more than 260 others at the race’s finish line. Prosecutors say he and his brother, now dead, also
killed an MIT police officer as they tried to flee days after the bombings.

Jury selection is expected to take at least three weeks as prosecutors and Tsarnaev’s lawyers haggle over
more than 1,200 potential jurors to be called. Testimony won’t begin until Jan. 26.

Prospective jurors got their first glimpse of Dzhokhar Tsarnaev on Monday as the scraggily haired
defendant fidgeted in a packed courtroom.

Twelve jurors and six alternates will hear the case against Tsarnaev, who faces possible execution if
convicted.

Choosing a jury will not be a quick or simple process.

U.S. District Judge George O’Toole Jr. told the potential jurors not to think of the trial as "an
annoying burden," but as a needed service and an "important duty of citizenship."

Federal prosecutors and Tsarnaev’s lawyers are trying to find jurors who can be fair and impartial.
Jurors must also be willing, if Tsarnaev is convicted, to consider imposing the death penalty in a state
that abolished its own death penalty three decades ago.

Defense lawyers have asked repeatedly that the trial be moved from Boston, where the bombings had a deep
emotional impact. O’Toole has refused so far.

Potential jurors were asked to fill out lengthy questionnaires to help whittle down the large jury pool.
Next week, Tsarnaev’s lawyers, prosecutors and the judge will begin questioning individual jurors.

The trial is perhaps the most scrutinized terror case in the U.S. since Timothy McVeigh was convicted and
executed for the 1995 Oklahoma City bombing.

Prosecutors say Dzhokhar and brother Tamerlan — ethnic Chechens who had lived in the United States for
about a decade — carried out the bombings in retaliation for U.S. wars in Muslim countries. Tamerlan,
26, died in a gunbattle with police days after the bombings.

The defense is expected to argue that Dzhokhar had a difficult childhood and fell under the evil
influence of his older brother.

In Russia, the brothers’ father again expressed the family’s distrust of the U.S. legal system.

"All the information that can refute the allegations against my sons is on the Internet," Anzor
Tsarnaev said by telephone from Grozny, the capital of Chechnya.
