O’FALLON — A prisoners rights group filed a lawsuit Monday alleging that a Missouri jail has been mistreating its inmates, saying deputies have taunted and tortured inmates and that the jail provided so little food that one detainee ate toothpaste and toilet paper to ward off hunger.

The lawsuit by the St. Louis-based civil rights law firm ArchCity Defenders was filed on behalf of Robert Hopple, Stefani Rudigier and Shawn Mesey, who recently were pretrial detainees at the Francois County Jail. The lawsuit names the eastern Missouri county, Sheriff Dan Bullock and the former jail administrator, along with the company providing medical care at the jail and a nurse. It seeks unspecified damages.
