Jury selection begins today in the trial of Boston Marathon bombing suspect Dzhokhar Tsarnaev. Three people were killed and 264 were wounded when a pair of homemade bombs exploded near the race’s finish line. Tsarnaev faces 30 federal counts, including the bombing of a public place, malicious destruction of public property, and use of a weapon of mass destruction resulting in death. He is accused of plotting the attacks with his older brother, Tamerlan, who died in a firefight with police. Federal prosecutors are seeking the death penalty, a rarity for a federal case.
