Boston Bombing Suspect Asks for Easing of Prision Conditions

Held in very severe isolation

Lawyers for Boston Marathon bombing suspect Dzhokhar Tsarnaev asked a judge Wednesday to lift restrictions placed on him in prison, arguing that the conditions are overly harsh, have left him nearly totally isolated and are impairing their ability to defend him.

Tsarnaev's lawyers said in court documents that he has been confined to his cell except for visits from them and "very limited access" to a small outdoor enclosure.

Tsarnaev, 20, is accused of building and planting bombs near the finish line of the April 15 marathon, killing three people and injuring more than 260. Authorities say he and his older brother, Tamerlan Tsarnaev, 26, ethnic Chechens from Russia who emigrated to the United States as children, planned and carried out the attack to retaliate against the United States for its involvement in Muslim countries.
