DES MOINES, Iowa (AP) — An Iowa woman who embezzled more than $518,000 has been sentenced to 20 months in prison on federal mail and tax fraud charges. Stacey Lynne Gross of Adel was also ordered to pay back the amount she stole from Data Business Equipment, Inc., which employed her as its Des Moines office manager. Federal prosecutors said Friday Gross wrote more than 190 checks for her personal benefit, including to pay for her credit card, mortgage and furniture, jewelry and other items. Prosecutors say the 38-year-old falsified the company’s books to cover up her theft, making it appear that a vendor received checks that used to pay her personal debts. Gross pleaded guilty in November. Company president Waldo Geiger issued a statement thanking investigators and noting insurance covered much of the theft.
