High Quality Content by WIKIPEDIA articles! The Washington sniper attacks took place during three weeks in October 2002 in Washington, D.C., Maryland, and Virginia. Ten people were killed and three others critically injured in various locations throughout the Washington Metropolitan Area and along Interstate 95 in Virginia. It was widely speculated that a single sniper was using the Capital Beltway for travel, possibly in a white van or truck. It was later learned that the rampage was perpetrated by one man, John Allen Muhammad, and one minor, Lee Boyd Malvo, driving a blue 1990 Chevrolet Caprice sedan, and had apparently begun the month before with murders and robbery in Louisiana and Alabama, which had resulted in three deaths.
