Three inmates - Michael Brown, Jerry Dunham, and Rex Dickey - allegedly attacked another inmate, Dwight Gibbs, on June 28, officials said. Staff intervened and were able to restrain the three inmates. It's unknown what may have prompted the alleged attack.

Gibbs was taken to the prison's medical unit then transferred to a local hospital where he later died from his injuries.
