RICHMOND, Va. (WVEC) -- The Virginia Attorney General's Office is appealing a federal judge's decision to throw out the two life sentences given to D.C. sniper Lee Boyd Malvo.

In May, the judge ordered Virginia courts to hold new sentencing hearings for Malvo who was 17 years old when he was arrested in 2002 for a series of shootings in the commonwealth, Maryland, and the District of Columbia. Ten people died and three other people hurt.

Malvo's accomplice, John Allen Muhammad, was put to death.

Attorney General Mark Herring's director of communication said Friday that Herring's office filed notices of appeal of the decision that ordered Malvo be re-sentenced. Malvo had convictions in Chesapeake and Spotsylvania.

The court should set a briefing schedule in the coming weeks.
