Glynn Ray Simmons

Glynn Ray Simmons is a former Oklahoma death-row prisoner whose capital conviction was ultimately undone. The Death Penalty Information Center records a 1975 conviction and a 2023 exoneration, a span of 48 years. The recorded exoneration procedure was Charges dismissed.

The wrongful conviction

Simmons was exonerated after 48 years between conviction and exoneration, one of the longest wrongful-conviction periods recorded in the modern U.S. death-penalty era.

Why the conviction failed

The documented factors connected to this case include: Mistaken Eyewitness Identification in Capital Cases, Official Misconduct in Wrongful Death-Penalty Convictions. DPIC does not classify DNA evidence as a major factor in this exoneration.

Those labels are not interchangeable. A case can combine official misconduct with unreliable witness testimony, weak forensic evidence, inadequate defense work or a false confession, and the legal route to exoneration can occur years after the first evidentiary problems become visible.

Exoneration and aftermath

Why the case matters

Death-row exonerations are a distinct part of capital-punishment history because they show how investigative error, unreliable evidence or procedural failures can survive through trial and years of appeals. Comparing these cases across states makes patterns easier to see than reading them as isolated stories.
