A four-month investigation of Blackman High School's football coaching staff and booster club's financial practices is done by the Rutherford County Sheriff's Office's Criminal Investigation Division, a supervisor said Wednesday.

No criminal charges will be brought against former head coach Phillip Shadowens, other coaching staff or booster club members by RCSO investigators, said Detective Capt. David Hailey.

Findings of the investigation were turned over to both Tennessee's Comptroller of the Treasury and the Compliance & Enforcement Division of the Internal Revenue Service, Hailey said.

James Evans, Community Relations Coordinator for Rutherford County Schools, said, "We appreciate the efforts of the detective and the Sheriff's Office to investigate this case. At this point, however, it is prudent for the school district to defer any additional comments until it can review the findings of the ongoing Comptroller's investigation."
