WASHINGTON—The Supreme Court has agreed to review the life-without-parole sentence of mass murderer Lee Boyd Malvo who was 17 years old when he and his older companion, dubbed the Beltway Sniper, committed 10 murders, terrorizing greater Washington for nearly two months in 2002.

The Supreme Court agreed on March 18 to review the case. The court will examine the life sentences without the possibility of parole that Malvo received in 2004, years before a landmark court ruling that found mandatory life sentences without the possibility of parole for those under 18 violated the Constitution in most cases.
