The small-town bookkeeper dazzled friends and co-workers with invitations to her horse ranch and home, where she displayed trophies from world championship exhibitions and visitors in cowboy hats arrived to buy some of the best-bred horses in the nation.
"She has a trophy case that you wouldn't believe -- actually a room," said Stephanie Terranova, who worked with Rita Crundwell for 15 years at city hall and attended her parties and auctions. "You wouldn't believe the different people that came. We don't have a lot of that type of thing around here. Cowboy boots, cowboy hats and southern drawls."
The gulf between Crundwell's two worlds was breathtaking, and her colleagues and neighbors never guessed how the two entwined: She is accused of using her modestly paid municipal job to steal their tax dollars, support an extravagant lifestyle and win national fame as a breeder.
Federal prosecutors say Crundwell, 58, who handled all of the city's finances, embezzled $30 million in public funds from Dixon, the boyhood home of the late President Ronald Reagan.
In a criminal complaint, they say they have obtained bank records that document each step she took in shifting taxes and other public funds through four city bank accounts before hiding them in a fifth account no one else knew about.
Still, they are trying to figure out how she kept the scheme a secret, even from outside auditors, for at least six years. It unraveled only when a co-worker filling in for Crundwell while she was on an extended vacation stumbled upon the secret bank account.
Crundwell had an encyclopedic knowledge of city business down to which drawer contained a particular document, said Mayor James Burke, who recalled feeling uneasy about the city comptroller's growing wealth.
"There wasn't anything to hang my hat on," said Burke, who has known Crundwell since she was a teenager. "Rita, she is a very, very smart person. I mean she is almost brilliant which I think probably was one of the reasons that a lot of people got bamboozled with her."
On Monday, the city fired Crundwell, who was arrested by FBI agents April 17 on a charge of wire fraud and later freed on a $4,500 recognizance bond.
Of the millions Crundwell is accused of funneling into the secret account, only six checks totaling less than $154,000 were ever spent on city business, according to prosecutors.
The rest, prosecutors say, went to her personal and business expenses, including at her horse farms in Dixon and just across the Wisconsin state line in the city of Beloit.
