Muhammad, 48, was put to death last week in Virginia for the killing of Dean Meyers at a gas station in October 2002. The murder was part of a three-week shooting spree that left 10 people dead and terrorized the Washington area.
The funeral was closed to the news media and family members did not speak to reporters after the service.
Muhammad’s accomplice, Lee Boyd Malvo, was 17 at the time of the shootings. He is serving life in prison without the possibility of parole.
