WASHINGTON - Maryland's highest court will begin oral arguments Tuesday in the case of Lee Boyd Malvo, who is serving life in prison for his role in the 2002 sniper spree that terrorized the Washington, D.C., region.
Malvo's lawyers have argued that his punishment goes against a 2012 Supreme Court ruling barring mandatory life sentences without parole for juvenile offenders.

His lawyers say he should benefit from Maryland's new law enabling prisoners convicted as juveniles to seek release once they've served at least 20 years.
Others were killed as the pair made their way to the D.C. region from Washington state. Muhammad was executed in 2009.

Malvo's lawyers have claimed that the six life-without-parole terms he received in Maryland are illegal in light of U.S. Supreme Court decisions saying mandatory life-without-parole sentences are unconstitutional for juveniles except in rare cases.
