PITTSBURG — A probable cause affidavit obtained by the Morning Sun fills in many of the missing details in the case of former Frontenac City Administrator Doug Sellars.

Sellars was arrested in September 2016, on five felony charges of making false information, official misconduct, misuse of public funds, theft and misdemeanor stalking.

The affidavit alleges that between Oct. 10, 2014 and Sept. 21, 2015, Sellars made 155 purchases with a city-issued credit card totaling some $11,831.77. Of those purchases, only 25 appear as legitimate city business.

Sellars is alleged to have spent in excess of $8,000 on personal expenses — including a pair of Global Positioning System tracking devices and monitoring services.

The misdemeanor stalking charge arises from the alleged use of those GPS devices to track his former mistress, after hiding them inside the bumper of her car.

According to the affidavit, submitted by Kansas Bureau of Investigation Special Agent Robert K. Jacobs, the entire matter came to light in August 2015, when Sellars allegedly told the former mistress’ supervisor he had placed the devices on her car.

Officers with the Pittsburg Police Department were informed, by the former mistress at the time, but were unable to find the tracker.

It was later discovered in a bumper by technicians at Creative Car Audio, in Pittsburg, the affidavit continues.

Purchases made by Sellars allegedly include three firearms, ammunition, Under Armor clothing and fireworks components, among other items.

Sellars told Jacobs one of the firearms, a Henry Golden Boy .22 caliber rifle, was given to former city administrator Dan Brunetti as a retirement gift, according to the affidavit.

Of the more than $8,000 worth of alleged personal purchases made by Sellars, he reimbursed the City of Frontenac for $856.37 between November 2014, and April 2015.

According to Jacobs’ affidavit, in order to hide the personal purchases, Sellars allegedly “notated on his UMB credit card statement, different city accounts, to which each individual charge on the credit card statement should be attributed.”

He then allegedly presented those to the Frontenac City Council for approval.

The financial crimes were discovered during a subsequent investigation regarding the stalking charges.

Sellars is expected to enter a plea on Dec. 12, in Crawford County District Court, in Pittsburg.
