John Allen Muhammad has been found guilty of killing six people in Maryland as part of the Washington-area Sniper killings.
Muhammad, 45, has already been sentenced to death by a Virginia court for his role in the sniper murders. The Maryland jury deliberated for only four hours before returning its verdict. Under Maryland law, the most Muhammad can receive as a sentence is life in prison without the chance for parole.
The key prosecution witness in the case was Lee Boyd Malvo, Muhammad's former partner in the slayings. Malvo, now 21, explained the elaborate plans Muhammad had for his terror spree which included killing six people per day for a month before a series of bombings at schools and children's hospitals. Malvo said Muhammad wanted to do it 'For the sheer terror of it -- the worst thing you can do to people is aim at their children.'
Malvo agreed to testify against Muhammad after pleading guilty to the Maryland killings. He gave authorities detailed information about each incident including where the pair parked their car.
During the sniper spree in 2002, 10 people were killed and three were wounded in Virginia, Maryland and Washington, DC.
Authorities in Maryland said they put Muhammad on trial in case his Virginia convictions were overturned on appeal.
Muhammad acted as his own lawyer in the case. He claimed he and Malvo were just roaming the area looking for the children he had lost in a custody battle with his ex-wife.
Muhammad and Malvo may still face charges arising out of earlier shootings in Alabama and Louisiana.
