A former employee at the Lake City Army Ammunition Plant in Independence admitted to stealing about $160,000 in equipment.

Brooke Brooks, 36, of Independence, pleaded guilty Friday in Federal Court in Kansas City to theft of government property. Brooks, a subcontractor who ordered equipment and supplies at the plant, admitted that she over-ordered on equipment and supplies by submitting phony invoices, then pocketed the profits from reselling the extra items, including power washers, electric drills and electric saws, on Craigslist, Ebay and to other Lake City employees.

According to court documents, Brooks' fraud scheme was discovered in February 2017 after a security manager received a complaint from someone who had yet to receive equipment ordered from Brooks. Brooks would advertise items to Lake City employees by claiming it was a part of a tool sale by her subcontractor to reduce excess inventory.

The investigation by Orbital ATK, which operated Lake City at the time and has since been purchased by Northrop Grumman, found that Brooks altered invoices by changing product descriptions, deleting invoices, combining part numbers and over-ordering. An Orbital accountant determined Brooks' scheme cost about $160,000.

Brooks will be sentenced at a later date.
