Charges: Mayo Clinic staffer's mileage swindle cost the hospital $72,000

The 50-year-old has been charged with theft-by-swindle.

A Mayo Clinic staffer has been charged with swindling her employer to the tune of almost $72,000 by filing fraudulent mileage claims over a three-year period.

Christine Chadderdon, 50, of Le Center, Minnesota, has been charged with theft by swindle for an alleged fraud carried out between 2015 and 2018, while she was a nurse manager for the Rochester-based clinic.

Chadderdon was responsible for the Mayo's Waseca Clinic and satellite locations in Janesville and Waterville, southern Minnesota, yet came under scrutiny from a forensic analyst at the health organization, who noticed unusually high mileage claims in the "Travel Logs" submitted by the Waseca location.

Chadderdon's role in Waseca didn't require any major traveling in southern Minnesota, and further examination of the trips she did claim for noted she had exaggerated the mileage on many of her submissions.

For example, she submitted a mileage claim for 112 miles for a journey between Waseca and Mankato – which is 60-mile round trip – while submissions for trips between Waseca and La Crosse, Wisconsin, were submitted as 396 miles, when in fact they should have been 226 miles.

She submitted claims for trips to Fairmont, Springfield, Mankato, Rochester, Le Center, La Crosse, New Prague, St. James, St. Peter, Eau Claire, and Lake City, despite her role not requiring her to undertake such visits.

Meanwhile, no mileage claims were made for visits to Janesville and Waterville, despite it being required as part of her job.

Further investigation could find no evidence that Chadderdon was actually at the locations she'd claimed mileage for. She's also accused of making mileage claims on 38 days on which she'd taken PTO.

"Chadderdon was claiming mileage for almost every day of the week for sites she was not even supposed to be at," the criminal complaint states.

The total value of the fraudulent travel logs was $71,759.73.
