BOSTON

- Boston Marathon bombing suspect Dzhokhar Tsarnaev returned to court yesterday for the first time since he was arraigned in July 2013, and he received a shout of encouragement from the mother-in-law of a man who was shot and killed while being questioned by law enforcement after the bombings.

Security was tight at the federal courthouse in Boston for Tsarnaev's final pretrial conference. Tensions ran high, and one bombing victim had a testy exchange with protesters outside.

During the brief court hearing, U.S. District Court George O'Toole Jr. made no rulings, saying he would rule in writing on pending motions, including the defense's latest push to move the trial out of Boston.

David Bruck, one of Tsarnaev's lawyers, told the judge that the defense plans to file a motion to delay the trial, which is now scheduled to begin on Jan. 5 with jury selection. Bruck did not say how long of a delay the defense will seek.

The mother-in-law of Ibragim Todashev called out to Tsarnaev in Russian in the courtroom. Elena Teyer said she told him: "We pray for you. Be strong, my son. We know you are innocent."

Later, in English, she yelled to the law-enforcement officers escorting her out of the room: "Stop killing innocent people. Stop killing innocent boys."

Tsarnaev never flinched or acknowledged the shouts.

Three people were killed and more than 260 were injured when two bombs exploded near the finish line of the April 2013 marathon. Tsarnaev, who has pleaded not guilty to 30 federal charges, faces the possibility of the death penalty if he is convicted.

Tsarnaev, 21, wore a black sweater and gray trousers and had a scruffy beard and a curly hairstyle similar to the one seen in earlier photos. He smiled to his attorneys and one patted him on the arm.

The courtroom was packed with FBI agents, police who worked on the case and more than a dozen survivors and family members.

Outside the courthouse, a man who lost his right leg in the bombings had a testy exchange with a small group of protesters holding signs supporting Tsarnaev and questioning whether authorities have proof that he is responsible for the bombings.

Marc Fucarile held up his prosthetic leg and moved it back and forth toward the demonstrators, saying: "That's proof right there."

One of the demonstrators said to Fucarile: "You should care that they get the right guy."

Fucarile replied: "Get a life, lady. Go to work."

Judge O'Toole questioned Tsarnaev about whether he had waived his right to appear at previous hearings. Tsarnaev answered in a clear voice: "Yes, sir."

Asked by the judge if he believes his lawyers had acted in his best interests, he said: "Very much."
