ENID — Garfield County Sheriff Jerry Niles and five other defendants are being blamed in second-degree manslaughter indictments of causing an inmate's death last year through negligence.

The indictments were made public Tuesday in Garfield County District Court.

The state's multicounty grand jury alleged in the indictments that Niles, 59, and the others caused the death of Anthony Huff by allowing the inmate "to remain in a restraint chair for over 48 hours without adequate food or water."

The sheriff — first elected in 2012 — pleaded not guilty Tuesday in his first court appearance and was led from the courthouse in handcuffs. Bail was set at $5,000.
