— The Lake Geneva Public Library staff member who last month admitted stealing about $18,500 from the library in the last two years is in more trouble.

Mercedes Mogensen, 44, Elkhorn, is accused of making more than $70,000 in personal purchases on the library’s city-issued credit card between July 2005 and May 2008. She was arrested Monday after police executed a search warrant at her home.

The Lake Geneva Police Department has referred possible charges of theft in a business setting and misconduct in office by an employee to the Walworth County District Attorney’s Office.

Library Director Andrea Peterson discovered the purchases earlier this month, police said.

Police found more than 475 fraudulent transactions on the credit card, which had been issued to Mogensen to make necessary purchases for the library. Police contacted the merchants and learned that many of the items were delivered to Mogensen’s home at W5685 Babcock Road in Sugar Creek Township.

The purchases include: furniture, a high-definition television, a laptop computer, sports equipment, jewelry, vehicle tires, clothing, cell phone and satellite television payments, tuition payments to UW-Parkside in the name of one of Mogensen’s children, gas, groceries, hotel stays and car rentals.

Mogensen was fired June 14 after she admitted stealing about $18,500 from the library between April 2006 and March 2008. She is charged with theft in a business setting of more than $10,000. Her initial appearance in Walworth County Court is Wednesday, Aug. 13.
