Hidden cameras placed inside an Ohio nursing home have led to 39 criminal charges, state officials have announced.

Relatives of residents began complaining to authorities about Autumn Health Care in Zanesville in December 2012, according to Ohio Attorney General Mike DeWine’s office. The relatives allowed hidden cameras to be placed in certain rooms, and these allegedly captured footage of staff providing poor care and falsifying documentation.

The press release from the AG’s office did not provide details about the alleged wrongdoings, and DeWine declined to go into specifics during a press conference Thursday, according to local reports.

Autumn Health Care owner Steven L. Hitchens, 58, faces charges of corruption, Medicaid fraud and forgery. The corrupt activity charge carries a mandatory 10-year prison sentence, the Zanesville Times-Recorder reported. An additional 16 charges have been brought against the facility as a whole. No staff members have been charged.

An Autumn spokesperson said the company had no comment as of press time.
