An inmate charged in the beating death of another inmate in McAlester has pleaded no contest to first-degree manslaughter.
Aaron Prado was set to go on trial this week in the July 2009 death of 45-year-old Kenneth Gore. The McAlester News-Capital reports that Prado was sentenced to 20 years in prison.
That sentence will run concurrent to the life sentence Prado is serving for a separate first-degree murder conviction from 2008 out of Cleveland County.
Prado was initially charged with first-degree murder in Gore's death but that was amended down to manslaughter.
Authorities say the two men got into a fist fight in a prison cell at the Oklahoma State Penitentiary. Gore was unresponsive when officers arrived and was pronounced dead in the prison's infirmary.
