IDAHO FALLS, Idaho (AP) — Bonneville County Sheriff Paul Wilde says an 18-year-old jail inmate has died of an apparent suicide.

Deputies conducting rounds discovered the inmate about 2 a.m. Saturday. Wilde says deputies attempted to provide medical care and called paramedics but the inmate had died. The inmate is from Shelley.

He'd been in the jail since Aug. 20, 2015 and was alone in his cell when he died. Investigators from Bingham and Madison counties are looking into the death.
