Donny Campbell, a former maintenance department employee at the Chickamauga and Chattanooga National Military Park, has pleaded guilty to theft of government funds after submitting false overtime entries on his timesheets.

Federal prosecutors say Campbell claimed overtime pay for hundreds of hours he did not work, with the false timesheets spanning January 2017 through June 2019. The government says the fraudulent claims resulted in nearly $40,000 in improper payments.

U.S. Attorney Theodore S. Hertzberg said federal employees are expected to be responsible stewards of taxpayer money and warned that those who steal public funds will be held accountable. The Interior Department’s Office of Inspector General said it will continue investigating similar cases to ensure government resources are used appropriately.

As part of a plea agreement, Campbell agreed to resign, never seek future federal employment, and pay full restitution to the U.S. Department of the Interior.

Campbell, 48, of Ringgold, pleaded guilty on October 2, 2025. Sentencing is scheduled for January 23, 2026, before U.S. Magistrate Judge John H. Rains IV. The case was investigated by the Department of the Interior, Office of Inspector General, and prosecuted by the U.S. Attorney’s Office.
