Muhammad, 48, looked calm and stoic, but was twitching and blinking, tapping his left foot as the injections began, defiant to the end, refusing to utter any final words.
Victims' families sat behind glass while watching, separated from the rest of the 27 witnesses, who were intent on what was happening as Muhammed died of injection at 9.11pm at Greensville Correctional Centre, south of Richmond.
He was executed for killing Dean Harold Meyers, who was shot in the head at a Manassas gas station during the spree across Maryland, Virginia and Washington, DC.
Nelson Rivera, whose wife, Lori Ann Lewis-Rivera, was gunned down, said that when he watched Muhammad's chest moving for the last time, he was glad. "I feel better. I think I can breathe better," he said. "I'm glad he's gone because he's not going to hurt anyone else."
Muhammad never testified or explained why he directed the shootings, and his secrets died with him.
"He died very peacefully, much more than most of his victims," said Prince William County prosecutor Paul Ebert.
Victims were shot down while doing everyday chores . A child was shot while walking into his school.
The terror ended on October 24 2002, when police captured Muhammad and his teenage accomplice, Lee Boyd Malvo, while they slept in a car at a Maryland rest stop.
Malvo, who was 17 when carrying out the attacks, was sentenced to life in prison without parole.
Muhammad's ex-wife believes the killings were a smoke screen for his plan to kill her and regain custody of their children.
