A former Bristolville man serving life in prison for murdering has pleaded "not guilty" to charges alleging that he killed a fellow inmate.

Twenty-five-year-old Austin Burke was arraigned Friday in a Scioto County, Ohio courtroom on on count of aggravated murder, two counts of murder, and one count of felonious assault.

Burke's trial is scheduled for July 22.

The Ohio Department of Public Safety told 21 News that Burke was involved in a fight with another inmate, 65-year-old Ruben Melendez at the Southern Ohio Correctional Facility on August 12.

During the fight, Melendez suffered serious injuries and was taken to the hospital, where he later died.

Burke was in prison for the murder of Kenneth Brandon Sample in June 2017 after being arrested following a robbery at a Cortland Pizza Joe's restaurant. The homicide took place in Bristolville, where Sample was found dead with a gunshot wound to the head at the Grand River Wildlife Area.

A jury convicted Burke in March 2018 on charges of aggravated murder, tampering with evidence, two charges of aggravated robbery, and weapons violations.

He was sentenced to life in prison with the possibility of parole in 30 years, followed by 11 years for the aggravated robbery convictions and firearm specifications. Those charges would keep Burke in prison for a minimum of 47 years.

Burke was handed another 11-year sentence for possession of a deadly weapon while in a detention center after he was found to have a "shank" in a Trumbull County Jail cell.
