(Greensburg/Shelbyville, IN) – A former Decatur County Commissioner entered a guilty plea to Theft and was sentenced this week in a Shelby County courtroom.
67-year-old Mark Koors of Westport was accused of overcharging the county on a fraudulent invoice for a piece of highway equipment bought through an online auction in November 2024.
Defense attorneys entered a written plea agreement on Koors’ behalf.
In exchange for the guilty plea on the Theft count, the prosecution dropped Official Misconduct and Forgery charges against Koors. All three counts were Level 6 felonies filed in August 2025.
Special Judge Jennifer Kinsley of Shelby County sentenced Koors to 730 days behind bars – all of which were suspended to two years supervised probation.
Ripley County’s Ric Hertel served as Special Prosecutor in the case.
Indiana State Police detectives began an investigation in January 2025 into allegations of theft and forgery that occurred in Decatur County late the previous year.
County officials alleged that while acting in his role as commissioner president, Koors forged documents and defrauded the county, which resulted in the theft of funds.
Court documents indicate Koors offered to bid on a loader on behalf of the Decatur County Highway Department through an auction website, on which he already had an account.
He allegedly turned in an invoice to the county that listed the price as $19,525 for the piece of equipment.
But court documents claim it was purchased for $8,305.
It was also alleged that Koors wrote a check to the county to make up the $11,220 difference after the discrepancy was discovered by the county auditor, but investigators examined his bank account and discovered that he did not have enough funds to cover the transaction for the equipment.
