A federal judge has thrown out two life sentences being served by Lee Boyd Malvo, one of two people convicted in the Washington, D.C., sniper killings of 2002.Judge Raymond Jackson in Norfolk, Va., ruled Friday that because the Supreme Court has found it unconstitutional to sentence juveniles to life without parole, Malvo is entitled to new sentencing hearings.Malvo was 17 when he was arrested, along with John Allen Muhammad, after a series of mysterious and terrifying shootings in Washington, D.C., Virginia and Maryland that killed 10 people and wounded three.Malvo said he met Muhammad in Antigua and took to the road with him. In an interview with The Washington Post in 2012 in a Virginia prison, Malvo said Muhammad "picked me because he knew he could mold me. ... He knew I could be what he needed me to be. ... He could not have chosen a better child.As they traveled, Muhammad and Malvo carried out a series of murders across the country, beginning in Washington state. Investigators later said Muhammad intended to kill his ex-wife, who lived in the Washington area. Muhammad was executed in Virginia in 2009. Copyright 2017 NPR. To see more, visit http://www.npr.org/.
