Library staffer facing more theft accusations
LAKE GENEVA 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.

Money has been an issue for the Mogensens for a long time. They are the kind of people that would never admit they aren't above others. Knew them years ago...some people never change.

Government agencies and public grant recipients are probably the easiest concerns to steal from. There are no owners with a vested interest to protect. Many, if not most of the employees are infected with the typical bureaucratic attitudes so prevalent in the public sector that they are over worked and under paid and that they are doing “good” for an ungrateful and overly demanding public. That it took so long isn’t what surprises me in this story, but that someone even noticed what was going on at all is. If Ms. Mogensen hadn’t gotten so bold, she could be secure in her job stealing smaller sums for years to come.

For a minimal fee you can do a background search and financial analysis on any potential employee that would be handling money. Previous payment problems, foreclosures, their credit score is all there to see and can be an indicator of potential problems. If there is a question they either don't get the position or are routinely scrutinized not given free reign for 3 or 4 years. My guess is this screening would have worked here and in the other cases mentioned.

It always kills me to see these types of things going on for three or four years at a time until somebody sees it. Poor controls over approvals, poor audit functions, poor management in general. Notice how these things are usually not private sector. Milton Schools, churches , libraries, UW-Whitewater.

Good point, that is alot of money that went unaccounted for. I hope this woman goes to prison. I would be a little more understanding if she were stealing food to feed her family, but an HD TV? Furniture? Give me a break. How humiliating for her family. She should be ashamed of herself.

Who ever is responsible for paying the credit card bill should be fired. Did they ask for receipts? All receipts should show what was purchased and for how much. Sure would not want that person doing my bookkeeping. Just turn in a bill and have it paid and for 3 years. This is just stupidity.
