D.C. sniper Lee Boyd Malvo will keep serving six consecutive life sentences without parole.
A judge has denied a motion for resentencing in the case of Malvo, the man convicted as a teen of taking part in the deadly 2002 sniper attacks that terrorized the D.C. area.
Malvo's attorney had argued that his client's life sentence is unconstitutional and should be thrown out.
On Wednesday, Judge Robert Greenberg of the Circuit Court of Maryland issued an opinion and order that the sentencing judge correctly considered all relevant factors in rendering Malvo's sentence.
Malvo, now 32, was convicted at age 17 in Maryland and Virginia for his role in the 2002 shootings that killed 10 people and wounded three in D.C., Maryland and Virginia. He later acknowledged shooting people in other states, as well. Malvo is serving his sentence at Red Onion State Prison in southwest Virginia.
His lawyer, James Johnston, argued in June that Malvo's sentence should be tossed because the U.S. Supreme Court has ruled that mandatory life sentences for juveniles are unconstitutional.
John McCarthy, spokesman for the Montgomery County State's Attorney's Office, said justice was served.

"The law has been complied with. People should have faith that justice was done originally at the time of the trial, at the time of the sentencing," he said.
John Muhammad, Malvo's partner in the shootings, was executed in 2009.
The shootings terrified the D.C. area. Residents lived in fear of who would be shot next.
"Everyone in Montgomery County and quite frankly the whole region was basically made prisoners in their own homes," resident Drew Powell said.
"They were just plucking people off," resident Keiana Ingram said.
