Boston Marathon bomber again tries to avoid execution

BOSTON (AP) — Boston Marathon bomber Dzhokhar Tsarnaev is again trying to avoid execution, asking the 1st U.S. Circuit Court of Appeals to consider four constitutional claims not taken up when his death sentence appeal went to the Supreme Court last month. Tsarnaev’s attorneys in a filing Thursday said the trial court “improperly forced” their client to stand trial in Boston; violated his constitutional rights; and allowed the admission of what they called a coerced confession. Thursday’s filing was in response to a Wednesday filing by the appeals court to comply with the Supreme Court’s decision last month to reinstate Tsarnaev’s death penalty.
