Defense attorneys for accused Boston Marathon bomber Dzhokhar Tsarnaev on Wednesday asked a federal judge to strike down the death penalty, calling it unconstitutional.
In court filings in US District Court, Tsarnaev's attorneys pointed to the fact that execution is not permitted In a Massachusetts, and said that the decision to attack the crowded marathon shouldn't be an "aggravating factor" in determining punishment.
They also argued that Tsarnaev may not have been indicted on 30 counts related to the bombing if the grand jury had anticipated he would be subjected to the death penalty if convicted.
Tsarnaev, 20, is being held at a Devens prison awaiting trial in the 2013 bombing, in which he and his late brother allegedly planted two pressure cooker bombs by the finish line, killing three and injuring more than 260.
