John Allen Muhammad, one of the "Beltway snipers" whose sharpshooting spree killed 10 people in the Washington, D.C., area, was executed on November 10, 2009.

His teenage partner in the 2002 wave of terror, Lee Boyd Malvo, laughed as he confessed gruesome details of the slayings.

Random victims were felled by single long-distance shots. A grocery store parking lot, lawns and a craft store all were targets. Four victims were shot doing this everyday task. A middle school student was shot, prompting this.

False leads led to widespread fear of these vehicles.

Clues on an occult card baffled police, but more notes - along with a phone call from a priest - narrowed the search. This woman may have been a key target all along.

The two were caught, courtesy of an alert truck driver. Here are details.

Muhammad had been a skilled Army sharpshooter, and victims were shot through an opening in the trunk of their Chevy Caprice. Check out pictures of the two after their capture.

Families received a $2.5 million settlement in a civil suit against this company. Some family members of victims plan to attend the execution.
