After hearing testimony, a Davidson County Grand Jury determined that "neither party committed a violation of any criminal statute."
The Grand Jurors heard testimony Tuesday, Aug. 7 by investigators from the Office of the Tennessee Comptroller, the Tennessee Department of Homeland Security and the Tennessee Highway Patrol.
The presentation included the results of the investigation of the travel expenses paid by the State for Jason Locke.
They made the determination to not indict later Friday.
Locke was placed on administrative leave in June after being made Acting Director for the Tennessee Bureau of Investigation.
Calls for his resignation came after several NewsChannel 5 Investigates stories.
The allegations against Jason Locke -- raised claims about a possible extramarital affair with another high-ranking state official at taxpayer expense -- were sent by Locke's wife, Kim, in an email to Tennessee Gov. Bill Haslam.
Locke's attorney released this statement after the decision was made.
