HASTINGS, Neb. (AP) — The Nebraska State Patrol is investigating the death of a 39-year-old inmate at Adams County Jail in Hastings.

The body was found in a cell around 6:30 a.m. Saturday. Sheriff Gregg Magee says the man’s death does not appear to be from natural causes.

Magee identified the man as Matthew Arterburn. Magee says the jail had been waiting on paperwork to send Arterburn to a state prison so he could serve his time there on convictions for child pornography.

Magee didn’t release any other information about Arterburn’s death.
