Darren Ray Padron, a 36-year-old inmate already tied to a deadly cell attack at a Holdenville prison, is now accused of killing a second cellmate at the Oklahoma State Penitentiary in McAlester. The new allegation, reported this week, is once again putting a spotlight on how violent prisoners are housed and supervised inside the state system. Padron remains behind bars while investigators and prosecutors sort through what happened.
According to The Oklahoman, Padron is accused of fatally stabbing fellow inmate Harrison Leon Duncan at the Oklahoma State Penitentiary. The outlet reported that Duncan suffered multiple stab wounds, including a count of 28 in its account, and that authorities are treating the case as a homicide. Prosecutors and prison investigators are reviewing evidence as they decide what to do next.
State records from the Oklahoma Department of Corrections list a "Duncan, Harris" entry dated March 17, 2026, at OSP, with the manner of death marked as "Homicide," confirming a lethal inmate death at the McAlester facility this spring. The DOC's online log notes that manners and causes of death may be updated after the Office of the Chief Medical Examiner completes its review, according to the agency.
Holdenville Attack And Plea Deal
A 2022 video, described in coverage from Yahoo, showed Padron strangling a cellmate at the facility then known as Davis Correctional in Holdenville while officers stood on the other side of the cell door as the victim pleaded for help. The reporting says officers used pepper spray and pepper balls and waited roughly 45 minutes before going in. That coverage also noted that Padron later pleaded guilty in 2024 to a reduced manslaughter charge, and that The Oklahoman had reviewed the video. Padron's mother told The Oklahoman that "he acted in self-defense."
Broader Staffing And Oversight Concerns
The video, a string of deaths at the Holdenville facility, and audits showing chronic understaffing have fueled broader questions about contractor oversight and emergency response inside Oklahoma prisons, as various news organizations have documented. The Associated Press previously detailed staffing shortfalls and multiple killings at the Holdenville facility and reported that audits showed the private operator ran well below contracted staffing levels.
Legal Implications And Next Steps
If prosecutors file charges in connection with the McAlester death, Padron could face new homicide counts and potentially decades behind bars if he is convicted. Earlier reporting said prosecutors at one point sought the death penalty in the Holdenville case before agreeing to a plea deal. Investigations by the ODOC inspector general's office and local prosecutors are the typical next steps in in-custody deaths, and families and advocates say they will be watching closely to see whether the state pursues accountability for any failures that may have contributed to the deaths.
