The Texas Department of Criminal Justice tells KFDM/Fox 4 News the agency is investigating the circumstances surrounding the death of a correctional officer.

The TDCJ says the officer in the Gib Lewis Unit in Woodville died last Friday.

They say his death is due to a self-inflicted injury. We've been told it was a gunshot wound.

Tyler County Sheriff Bryan Weatherford says his office is aware of the incident involving the guard, and that the Office of Inspector General Is part of the investigation.

Weatherford says his office was not asked to respond because it was an 'isolated incident handled internally.'
