Fourth Prisoner Dies After Cushing Riot

A fourth inmate has died after riots at the Cushing prison. Three inmates are still in the hospital where they are said to be stable, according to the Oklahoma Department of Corrections. 

The deadly riot was in a single housing pod and lasted about 40 minutes Saturday afternoon at the Cimarron Correctional Facility which is owned and operated by Corrections Corporation of America. 

CCA said the "inmate-on-inmate" altercation lasted two minutes with staff working to secure the housing area for another 38.

Preliminary reports show that the first three inmates to die were fatally stabbed, but officials did not know the nature of the injuries to any of the other inmates, including the one who died overnight.

The facility remains on lockdown while an investigation is ongoing. CCA said in a release that they are working closely with officials from the Oklahoma DOC Office of Inspector General, and will cooperate fully with its ongoing investigation. 

The identities of the dead and injured inmates are pending release upon notification of next of kin. Medium- and maximum-security male inmates are held at the 1,720-bed Cushing prison.

"Further details will be provided as they become available," a news release states.
