HARVARD – A former School District 50 employee charged more than $20,000 to a district credit card and Walmart card, according to police.

Krystal Ohlenroth, who was fired as the district’s accounts payable clerk Oct. 23, is charged with theft of more than $10,000 of government property, a Class 1 felony, and theft of more than $10,000, a Class 2 felony.

Harvard Police Chief Dan Kazy-Garey said the unauthorized purchases began in early 2012 and were for “everyday expenses.” “Some were cash, others were for entertainment, various clothing items,” he said.
