An Arizona prison inmate is dead from an apparent homicide, state Department of Corrections officials said.
John Jones, 63, died Monday at the Lewis complex in Buckeye.
DOC officials stopped short of saying what happened to Jones.
They said prison staff and medical responders administered CPR to the inmate. He was transported to West Valley Hospital, where he was pronounced dead.
An investigation into the death will be led by the department's Criminal Investigation Unit in consultation with the Maricopa County Medical Examiner's Office.
Jones was sentenced out of Yavapai County and was serving 40 years for sexual assault, aggravated assault and kidnapping. He had been in prison since March 2000.
