The  National Law Enforcement Museum has received a collection of artifacts relating to the 2002 case involving John Allen Muhammad and Lee Boyd Malvo, who were known as the Beltway Snipers .

The Prince William County (Va.) Police Department donated the complete inventory of task force evidence relating to the attacks that terrorized the greater Washington area for 23 days in October of 2002. The agency donated the materials in July.

The collection contains the blue 1990 Chevy Caprice that Muhammad and Boyd Malvo used for the attacks and physical evidence related to the individual sniper incidents in D.C., Maryland, and Virginia.

Ten people were killed and three others were critically injured in the attacks. Muhammad was sentenced to death in September 2003 and executed on Nov. 10, 2009 by lethal injection. In October 2003, Boyd Malvo was sentenced to six consecutive life sentences without the possibility of parole.

The evidence consists of items such as bullet fragments and a tarot card recovered from various crime scenes, a blue can of spray paint used to camouflage the inside of the car's trunk, and everything from inside the Caprice when the two men were captured, including several maps and atlases.

One of the museum's earliest changing exhibits in the DuPont Gallery will display items from this collection to tell the complex story of the investigation and solving of the Beltway Sniper case. The museum is scheduled to open in early 2015.
