Penitentiary staff member injured in assault by inmate

(Sioux Falls, S.D.)- A security staff member at the Jameson Annex to the South Dakota State Penitentiary is recovering after being assaulted by a state prison inmate last evening.

Shortly after 8:00 p.m. on April 20, Inmate Carlos Green punched Corporal Zane Mathis in the head several times. The inmate was handcuffed by other staff and locked up in a disciplinary section of the prison. The Jameson Annex was placed in lock down status as a precautionary measure for the remainder of the evening.

Corporal Mathis was transported to a Sioux Falls hospital for treatment. He suffered a fractured jaw and facial lacerations in the assault.

Green, age 28, is currently serving a 35 year sentence for aggravated assault, a consecutive 5 year sentence for eluding a police officer and a consecutive 2 year sentence for sliming. All of the sentences are from Brown County.

The lock down of the Jameson Annex was lifted today and the prison is fully operational.

The Division of Criminal Investigation is investigating the assault.
