LINCOLN, Neb. (AP) — State prisons officials say an inmate at the Nebraska State Penitentiary in Lincoln has died.
The Nebraska Department of Correctional Services says in a news release that 48-year-old Keeva O'Neal died Sunday night.
Officials said they have not determined O'Neal's cause of death, but said he was being treated for a medical condition at the time of his death.
Officials did not disclose the nature of O'Neal's medical condition.
O'Neal was serving a 45- to 65-year sentence for first-degree assault and weapons counts.
He began serving the sentence in April 1997.
State law requires a grand jury investigation any time a person dies in state custody.
