McLEAN, Va. (AP) — Questions about how many people the D.C. snipers killed aren't expected to end with Tuesday's execution of mastermind John Allen Muhammad.
Police in agencies around the country think Muhammad and his accomplice Lee Boyd Malvo may be responsible for several more shootings outside the Beltway. Malvo has reportedly confessed to as many as 27 shootings. But he won't testify unless he's granted immunity, so some killings remain unsolved.
The attacks in a three-week stretch seven years ago terrorized the Washington area. It wasn't until Malvo and Muhammad were arrested that authorities began to suspect them in other shootings.
Muhammad is set to die by injection Tuesday in Virginia. Malvo is serving life in prison without parole.
