Authorities in Cole County are investigating a homicide Wednesday.
Sheriff Greg White told ABC 17 News the homicide happened inside the Jefferson City Correctional Center on Algoa Road late Tuesday night. JCCC is a state maximum security prison.
Officials say the homicide involved two male inmates, one of which is dead.
The inmate has been identified as 67-year-old Jose T. Benitez, according to the Department of Corrections.
Court records state Benitez was sentenced to 25 years in prison for first-degree statutory sodomy out of Jasper County. He has been in the Department of Corrections since March 2012.
They have not released the name of the suspect because charges have not been filed yet.
Authorities say the homicide happened sometime Tuesday afternoon and Benitez's body was found in a locked cell.
It's not clear how long the victim and suspect had shared the cell.
Officials say they collected 47 pieces of evidence at the scene.
An autopsy will be conducted in Columbia with results expected by the end of the week. Officials say no weapons or sharp objects were found in the cell.
