BOSTON (AP) — A federal judge has formally sentenced Boston Marathon bomber Dzhokhar Tsarnaev to death for the 2013 terror attacks.

U.S. District Judge George O’Toole Jr. pronounced the sentence Wednesday in Boston. He was required under law to impose the jury’s death sentence for the April 15, 2013, attack that killed three people and wounded more than 260 others.

The judge says no one will remember that his teachers or friends were fond of him. He says what they will remember is that Tsarnaev “murdered and maimed innocent people” and “did it willfully and intentionally.”

Tsarnaev looked down and rubbed his hands together as the judge sentenced him.

An appeal is automatic in death penalty cases.
