Authorities say an Ohio inmate has died after a fight with his cellmate. The State Highway Patrol says staff at the Mansfield Correctional Institution found 62-year-old Robert Parr in his cell shortly after 10 p.m. last night. Patrol spokeswoman Lt. Anne Ralston says Parr was taken to a hospital and pronounced dead about an hour later. The cause of death has not been released. Ralston says no details of the fight have been released and no charges have been filed. Ralston says Parr entered the prison in 2007 after his conviction on rape charges. He was serving a sentence of 10 years to life.
