KNOXVILLE, Tenn. (WATE) – A former high-ranking officer in the Knox County Sheriff’s Office is now under federal indictment accused of treating seized drug money as a personal piggy bank to benefit himself, an unnamed former Knox County Sheriff, and several co-conspirators. That sheriff is not identified by name in the indictment.
Assistant Chief David Henderson, head of the county’s Narcotics Unit, entered a not guilty plea in court today in response to a federal indictment handed down Feb. 16.
That indictment accuses Henderson of directing subordinates to use Narcotics Unit cash and credit cards to make purchases for personal use, as well as using Knox County vehicles, supplies and machinery to complete personal projects at Henderson’s home, the former sheriff’s home and at the homes of friends, family and acquaintances.
The document alleges that the Narcotics Unit credit card, which is assigned to the unit by the Knox County Government, was used to purchase approximately $138,000 of Apple electronics.
The Narcotics Unit is fully funded by the Knox County general fund. Three percent of that fund is made of federal grant money that is paid to provide for the housing of federal detainees in the Knox County Jail.
The Charge: One Count of Conspiracy to Commit Federal Program Fraud
Henderson has been indicted with one count of conspiracy to commit federal program fraud. The indictment details allegations against Henderson and “co-conspirators” for actions around 2011 through September 2018.
The federal indictment lists the following accusations:
- Directing certain Narcotics Unit officers to perform renovation, remodeling and construction projects of a purely personal nature at various locations, including the private residence of an unidentified former Knox County Sheriff, at Henderson’s private residence, and the private residences of family members, associates and friends
- Using Narcotics Unit cash to purchase items for their own personal use, and for that of a former Knox County Sheriff
- Using the Narcotics Unit credit cards to purchase items for their own benefit, or for the benefit of family, associates or friends
- Concealing the purchases that were made by submitting expense reports and credit card statements to the Knox County Finance Department and claiming the purchases were for official purposes when they knew they were not

Henderson controlled the cash fund and credit cards for the Narcotics Unit. The indictment states Henderson did not personally use the Narcotics Unit credit card but instead directed subordinates to use the credit cards or cash “on several occasions.” Items were purchased for Henderson’s personal use and for the use of a former Knox County Sheriff, as well as family and friends of those in the Narcotics Unit.
