Sonia Hollingsworth-Wills, the mother of Conrad Johnson, the last man slain that October, sat in the back seat of a car outside the prison before the execution, which she chose not to witness. But she said she wanted to be there and was counting the minutes until Muhammad's death.
"It was the most horrifying day of my life," she said. "I'll never get complete closure but at least I can put this behind me."
Cheryll Witz, who's father, Jerry Taylor, was fatally shot on a Tucson, Ariz., golf course in March 2002, said she was unhappy that Muhammad didn't say anything before he died. But she said his execution begins a new chapter in her life.
"I've waited seven long years for this," she said. "My life is totally beginning now. I have all my closure, and my justice and my peace."
