ORD,Thomas Caldwell Neb. (AP) — A small-town Nebraska sheriff is facing a felony charge, but few details about the allegations against him were immediately available.

The Nebraska State Patrol said Valley County Sheriff Casey Hurlburt was arrested Tuesday, and prosecutors with the state Attorney General’s office plan to charge him with fraudulent insurance acts after investigating him for months.

But Nebraska Attorney General’s office spokeswoman Suzanne Gage said she couldn’t disclose any details about the case, and the complaint against Hurlburt wasn’t available in court records Wednesday morning. The Nebraska State Patrol referred all questions to the AG’s office.

Hurlburt has been released from custody, but Hall County Jail officials don’t have any records showing whether he posted bail because he has been released.

Hurlburt isn’t scheduled to make his initial court appearance until Oct. 25.

The Associated Press left a message for Hurlburt Wednesday morning, but a woman who answered the phone there said he hadn’t been in the office in Ord since his arrest. The case isn’t listed in online court records yet, so it’s not clear if he has an attorney.

Ord is a small town in the middle of Nebraska about 185 miles (about 300 kilometers) west of Omaha. About 4,000 people live in Valley County.
