WASECA, Minn. (AP) — A former nurse manager for Mayo Clinic in Minnesota is accused of making nearly $71,000 in false mileage reimbursement claims.

The Mankato Free Press reports that 50-year-old Christine Chadderdon, of Le Center, is charged in Waseca County District Court with felony theft by swindle.

Authorities say Chadderdon worked as a nurse manager for the Mayo Clinic facilities in Waseca, Janesville and Waterville. She resigned after finance staff began investigating unusually high travel expenses in her department.

A complaint says Chadderdon allegedly claimed trips she never made and inflated the number of miles traveled. Documents show she recorded round trips from Waseca to Mankato as 112 miles, when it's less than 70 miles.

Court documents do not list an attorney for Chadderdon. A phone number listed for her was disconnected.
