TERRE HAUTE, Ind. — An inmate has died after an apparent fight with another inmate at a federal prison in western Indiana, officials said.

The Federal Bureau of Prisons said inmate Mario Waters, 35, was found unconscious at the U.S. Penitentiary in Terre Haute about 12:20 a.m. Monday after a “observed altercation” with another inmate.

Despite life-saving efforts, Waters was pronounced dead later Monday at a Terre Haute hospital.
