Docs: Former Decatur Co. commissioner created fraudulent invoice after auction purchase

GREENSBURG, Ind. — A former member of the Decatur County Board of Commissioners allegedly overcharged the county in a fraudulent invoice for a piece of highway equipment purchased in an online auction.

According to court documents recently filed in Decatur County, 66-year-old Mark Koors, a Greensburg man, has been charged with:

• One count of official misconduct, a Level 6 felony
• One count of forgery, a Level 6 felony
• One count of theft, a Level 6 felony

In January 2025, detectives with the Indiana State Police were asked to investigate an allegation of theft and/or forgery that occurred in Decatur County in November 2024. County officials alleged that Koors, when he was an acting commissioner in the county, “forged documentation and defrauded the county, resulting in the theft of funds.”

In November, officials with the Decatur County Highway Department wanted to purchase a 1977 Athey 702-113 Belt Loader through an auction website. The court documents allege that Koors, who already had an account on the auction’s website, offered to bid on the item for the county.

After Koors’ bid, the county won the auction, and the machinery was delivered to the county’s highway garage. The documents allege that Koors then created an invoice for the item, charging the county $19,525 for the machinery.

After the machinery was delivered, county officials found that there was an item missing from the equipment that had been included in the purchase agreement. A county employee reportedly drove down to the auction location in Kentucky to retrieve the item.

As the employee was there, they allegedly found that Koors had paid $8,305 for the piece of machinery. The documents said that the auction company then provided the county with the correct invoice.

When confronted by the county’s auditor, Koors reportedly wrote a check for the difference in invoices, totaling $11,200. The documents said that in an interview with law enforcement, Koors admitted to creating the invoice for $19,525, advising that he had not received an actual invoice from the auction company.

In the interview, Koors claimed that during the auction, the website went down, causing a representative from the website to contact Koors and ask what his highest bid on the equipment would be. Koors responded by providing the $19,525 figure.

When Koors won the auction, he reportedly told detectives he believed the amount the equipment was purchased for was the highest bid. Because he claimed the company did not provide an invoice for the transaction, he created his own.

As investigators looked at Koors’ checking account, the documents claim that he did not have enough funds to cover the transaction for the equipment. If the equipment had been purchased for the highest bid, officials said there would have been an overdraft that would have prevented the purchase.

The documents claim that the amount that the piece of equipment was purchased for was $8,305, a figure less than the $19,525 that Koors invoiced the county for.

In a statement provided to FOX59/CBS, officials with the Decatur County Board of Commissioners said they are aware of the recent criminal charges filed against Koors.

“Decatur County dutifully cooperated with the investigation conducted by the Indiana State Police,” the statement read, “and will make no further comment during the pendency of this matter.”

According to court documents, Koors’ bond was set at $7,500, with 10% cash allowed, by a Decatur County judge. Koors’ pretrial conference is scheduled for Oct. 27 and his jury trial is scheduled for Jan. 26, 2026.
