John Allen Muhammad and Lee Boyd Malvo were captured

The Beltway sniper attacks were a series of coordinated shootings that took place over three weeks in October 2002 in Maryland, Virginia, and Washington, D.C.. Ten people were killed and three other victims were critically injured in several locations throughout the Washington, D.C. metropolitan area and along Interstate 95 in Virginia. It was widely speculated that a single sniper, initially identified as a white man with assumed military experience, was using the Interstate 495 Capital Beltway for travel, possibly in a white van or truck. It was later learned that the rampage was perpetrated by an African-American man, John Allen Muhammad, and a minor, Lee Boyd Malvo, then aged 17 and originally from Jamaica, driving a blue 1990 Chevrolet Caprice sedan, and had apparently started in February 2002 with murders and robberies in Alabama, Arizona, California, Florida, Georgia, Louisiana, Texas, and Washington State, which resulted in seven deaths and seven injuries, bringing the total victim count to seventeen deaths and ten injuries in Alabama, Arizona, California, Florida, Georgia, Louisiana, Maryland, Texas, Virginia, and Washington State, as well as D.C.

In September 2003, Muhammad was sentenced to death. One month later, Malvo was sentenced to six consecutive life sentences without the possibility of parole. On November 10, 2009, Muhammad was executed by lethal injection at the Greensville Correctional Center in Jarratt, Virginia.
