COUNCIL BLUFFS, Iowa (AP) — Three Iowa child sex cases against a Nebraska jail officer have been consolidated.

Shawn Beu has pleaded not guilty to the charges, which include sexual abuse, sexual exploitation of a minor and possession of child pornography. His trial is scheduled to begin June 1 in Pottawattamie County District Court. A judge has barred most of the court documents from public scrutiny.

Beu was arrested on warrants after a search of his Council Bluffs home. He’s a corrections sergeant at the Douglas County Jail in Omaha. A spokesman for the Douglas County Sheriff’s Office didn’t immediately return a call Friday.
