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. Although Mitchell Sims carried out the fatal shooting, prosecutors successfully argued that Padgett was an active participant in the kidnapping and robbery that led to Harrigan's execution. 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.

Early Life
On May 20, 1986, Pizza Hut delivery driver John Steven Harrigan responded to what appeared to be a routine delivery call in Las Vegas, Nevada. Prosecutors alleged the delivery had been arranged as part of a robbery planned by Mitchell Sims and Ruby Padgett.
Authorities stated Harrigan was abducted, robbed, and forced into his own vehicle before being driven into the Nevada desert. There, Sims shot Harrigan execution-style before abandoning his body. Prosecutors argued Padgett actively participated in the kidnapping and robbery that directly resulted in the murder.
Although Mitchell Sims was identified as the gunman, jurors concluded Padgett's involvement in the underlying felony made her legally responsible for Harrigan's death. The murder became one of the most widely publicized crimes associated with Sims' interstate killing spree.
Killing Spree
Prosecutors portrayed Ruby Padgett as an active accomplice rather than a passive observer. Authorities alleged she assisted Sims in selecting victims, participating in robberies, and helping facilitate crimes targeting pizza delivery workers.
The prosecution argued that Padgett knowingly took part in the robbery that led directly to John Harrigan's murder. Under the felony murder doctrine, prosecutors maintained that every participant in the armed robbery shared responsibility for the killing, regardless of who fired the fatal shot.
Evidence presented during trial demonstrated Padgett remained with Sims throughout the offence and continued travelling with him after the murder. Prosecutors argued her actions reflected voluntary participation in the criminal enterprise rather than coercion.
Modus Operandi
Following John Harrigan's murder, investigators began piecing together witness statements, forensic evidence, and vehicle information connected to the robbery. The investigation eventually identified Mitchell Sims and Ruby Padgett as the primary suspects.
Law enforcement later arrested the pair after tracing their movements across several states. Detectives gathered evidence linking both individuals to the kidnapping, robbery, and murder of Harrigan.
As investigators continued examining Sims' activities, they also connected him to additional murders in South Carolina. Although Padgett was investigated in relation to those crimes, her murder conviction stemmed from the Harrigan case in Nevada.
Capture
Ruby Padgett stood trial for her role in the kidnapping, robbery, and murder of John Harrigan. Prosecutors argued she willingly participated in the armed robbery that culminated in Harrigan's execution-style killing.
The state presented witness testimony, forensic evidence, and investigative findings demonstrating Padgett's involvement alongside Mitchell Sims. Jurors accepted the prosecution's argument that she shared legal responsibility for the murder despite not firing the fatal shot herself.
Padgett was convicted of first-degree murder, robbery, and related offences. She was sentenced to life imprisonment without the possibility of parole and has remained incarcerated since her conviction.
Trial & Sentence
Ruby Padgett's case is frequently discussed alongside Mitchell Sims because the two operated together during portions of his interstate crime spree. Although Sims became far more widely known, Padgett's conviction illustrates how accomplices can be held equally responsible under felony murder laws when a death occurs during the commission of a violent felony.
The case also highlighted the dangers faced by pizza delivery drivers during the 1980s. A series of highly publicized robberies and murders targeting delivery employees prompted many companies to introduce improved safety procedures, cash restrictions, and delivery policies.
Today, Padgett remains a relatively obscure figure compared to Sims, yet her conviction permanently links her to one of America's most infamous robbery-murder cases involving pizza delivery workers.
