LUCASVILLE, Ohio - A former Bristolville man who was found guilty of murdering a Warren man in 2017 was involved in a prison fight that left a man dead.

The Ohio Department of Public Safety told 21 News that Austin Burke, 25, was involved in a fight with another inmate, 65-year-old Ruben Melendez at the Southern Ohio Correctional Facility in Scioto County. The dispute between the two men took place on August 12 and led to a confrontation between the two men.

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

Burke was charged with 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 that April 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.

The fight at the maximum security Southern Ohio Correctional Facility remains under investigation.
