Over the course of three weeks in October 2002, John Muhammad, 41, and John Lee Malvo, 17, randomly shot and killed 13 people in a sniper rampage that took them from Washington D.C., to Rockville, Maryland and Fredericksburg, Virginia. They were eventually found sleeping in their 1990 Chevrolet Caprice — which had a small hole in the trunk through which the two were able to aim without being detected — along Interstate I-95 in on the night of October 24. Through notes and phone calls they had unsuccessfully demanded $10 million. When they were apprehended, investigators learned that the two were linked to six other shootings, three of them fatal, in other states. The pair used two-way radios to communicate during their murder spree and alternated as shooter and lookout man. For their crimes in Virginia, Muhammad was sentenced to death; Malvo, tried as an adult, received a life sentence. In Maryland, both men were sentenced to six consecutive life terms without the possibility of parole.
