It's been 18 days since an inmate complained that two Rhea County sheriff's deputies beat him, kicked him in the face and groin and slammed him against a patrol car after he surrendered to police.

Rhea County Sheriff Mike Neal, though, says he won't open an investigation unless he gets a direct complaint from inmate Walter Gann. On Monday, Neal said an officer had interviewed Gann in the Rhea County Jail and Gann had told the officer "he was happy" to be there and "wanted to be in jail."

The complaint by Gann, 36, originated from an arrest May 30, when Gann led police on a 65-mile chase through Dayton, TN., after escaping from a Dade County, Ga., jail work site in a public works truck. The Chattanooga Times Free Press obtained a copy of a written complaint after Gann was arrested and was hospitalized complaining of rib pain.

The Graysville Police Department did an internal investigation of the incident, and police Chief Erik Redden said he found the inmate's complaint to be valid.
