Federal prosecutors allege that the nonprofit Feeding Our Future spearheaded the nation's largest pandemic fraud scheme by taking in more than $250 million meant to feed needy kids, most of whom were not actually served.

Here's how federal authorities allege it happened, according to criminal charges:

1. Greasing the wheels: Feeding Our Future, led by founder and executive director Aimee Bock, is accused of accepting bribes and kickbacks from entities in exchange for sponsoring applications for the federal child nutrition program. One of the biggest fraud recipients, for instance, allegedly paid more than $350,000 to Bock and one of her employees in exchange for the nonprofit's cooperation. Smaller players paid as little as $14,000. Many bribes were camouflaged as consulting fees.

2. Working the scam: Conspirators set up feeding sites where they claimed to be serving as many as 5,000 meals per day to needy children, even though some sites served few or no meals. In some cases, conspirators also set up companies that sold food to meal sites they controlled or were affiliated with.

3. Faking the numbers: To obtain payment, site operators created fake meal count sheets and filled out attendance rosters with the names and ages of fictitious children. In some cases, sites claimed identical number of meals each day — a red flag to monitors. Vendors submitted fake invoices documenting phony or inflated food and beverage purchases.

4. Getting rich: Charges say Bock and Feeding Our Future submitted fraudulent reimbursement claims to the Minnesota Department of Education, which oversees the federal program in Minnesota, to obtain money for the meal providers and food vendors. The payments should have barely covered the providers' costs, but the conspirators were able to pocket millions of dollars because their true expenses were so low.

5. Spending the loot: Conspirators used the money they fraudulently obtained from the government to purchase resort homes, investment property, luxury cars, jewelry and vacations in the U.S. and abroad. Federal prosecutors have so far seized $50 million in assets.

Who is involved?

Charges have been filed against six groups that allegedly participated in the conspiracy, but the government said more charges are coming. The six main conspirators controlled nearly 60 meal sites in Minnesota and received at least $160 million in fraudulent money, prosecutors allege.
