Boston Marathon survivors, families get no satisfaction from suspect's arraignment on charges

BOSTON – As victims of the Boston Marathon bombings looked on, the suspect in the deadly twin explosions made his first public appearance since his capture.

Dzhokhar Tsarnaev pleaded not guilty to 30 charges Wednesday during a seven-minute arraignment in federal court.

Peter Brown, the uncle of two men who lost their right legs in the April 15 explosions, said he thought Tsarnaev had a smirk on his face during the hearing. He said he had hoped Tsarnaev might look like he cared.

Tsarnaev could face the death penalty if prosecutors choose to pursue it. The explosions near the marathon's finish line killed three people and injured more than 260. Tsarnaev's older brother, Tamerlan, who prosecutors say plotted and carried out the bombings with Dzhokhar, died after a shootout with police.
