JACKSBORO, TN. (WLAF)- As one school official returned to his job yesterday, another is still under investigation.

Wednesday morning, Campbell County High School Principal Ben Foust returned to his position following an investigation by the sheriff’s office and his legal counsel, the Isaacs Law Firm. There was “no substance” found in the allegations that prompted Foust’s unpaid administrative leave in March, according to a press release from the firm.

“There was nothing to charge him with,” said CCSO Chief Deputy Cody Chapman.

Jason Austin, the CCHS soccer coach, remains under investigation. “We are still going through the process,” said Chapman on Wednesday. Austin’s alleged victim is now an adult, but the incident is reported to have occurred when she was a minor, officials said.

While the two were suspended just days apart, the allegations were unrelated, Campbell County Director of Schools Jennifer Fields said at the time.

Foust’s legal woes appeared to have started with an anonymous tip, Isaacs’ press release said. The tip was “malicious” and led to “false allegations” against Foust, according to the release.
