Ruby Carolyn Padgett became known in American criminal history after being convicted of first-degree murder for her role in the 1986 robbery and murder of Pizza Hut delivery driver John Steven Harrigan in Las Vegas, Nevada.

Convicted under California's felony murder principles, Padgett received a sentence of life imprisonment without parole. Often overshadowed by Sims, who became known as the "Pizza Hut Serial Killer," Padgett remains a convicted murderer whose participation was instrumental in one of the most infamous pizza delivery murders in the United States.
