MINNEAPOLIS (AP) — A jury deliberated for a second day Wednesday in the trial of seven Minnesotans accused in a scheme to steal more than $40 million from a program meant to feed children during the coronavirus pandemic, while FBI agents try to establish who left a bag with $120,000 in cash for a juror.

Federal authorities confiscated the defendants’ cellphones to search for clues and took all seven into custody on Monday before deliberations began. The trial judge also sequestered the jury after dismissing the juror who turned over the gift bag, along with another juror who reported hearing about the bribe attempt.

According to an FBI agent’s affidavit, a woman rang the doorbell at the home of “Juror #52” in the Minneapolis suburb of Spring Lake Park late Sunday, the night before the case went to the jury. The juror wasn’t home, so the woman handed her relative a gift bag with a curly ribbon and images of flowers and butterflies, saying it was a “present” for the juror.

“The woman told the relative to tell Juror #52 to say not guilty tomorrow and there would be more of that present tomorrow,” the agent wrote. “After the woman left, the relative looked in the gift bag and saw it contained a substantial amount of cash.”

The juror called police right after she got home and gave them the bag, which held stacks of $100, $50 and $20 bills totaling around $120,000.

U.S. District Judge Nancy Brasel and attorneys for both sides learned about the attempted bribe Monday morning, before the last closing arguments.

Minneapolis FBI spokesperson Diana Freedman said Wednesday the investigation is ongoing and no further information is public. No arrests have been announced.

Anyone involved in the attempted bribe could face federal charges of bribery of a juror and influencing a juror, with a maximum potential penalty of 15 years in prison.

The seven defendants are the first of 70 to stand trial in what federal prosecutors have called one of the nation’s largest COVID-19-related fraud cases, an extensive scheme to exploit rules that were kept lax so that the economy wouldn’t crash during the pandemic.

Prosecutors say the seven collectively stole more than $40 million from a program designed to feed children in Minnesota, and that the overall conspiracy diverted $250 million in federal funds.

At its center was a nonprofit called Feeding Our Future. Prosecutors say just a fraction of the money went to feed low-income kids, with the rest spent on luxury cars, jewelry, travel and property. Federal authorities say they have recovered about $50 million.

Eighteen other defendants have pleaded guilty. Those awaiting trial include Aimee Bock, the founder of Feeding our Future. She has maintained her innocence, saying she never stole and saw no evidence of fraud among her subcontractors.

These seven defendants are: Abdiaziz Shafii Farah, Mohamed Jama Ismail, Abdimajid Mohamed Nur, Said Shafii Farah, Abdiwahab Maalim Aftin, Mukhtar Mohamed Shariff and Hayat Mohamed Nur. All were charged with wire fraud conspiracy and money laundering, and some faced additional charges in the 43-count indictment. Each had their own lawyers.

The common thread in their defense is that investigators failed to dig deep enough to see they served real meals to real kids.

The food aid came from the U.S. Department of Agriculture and was administered by the state, which funneled the meal money through nonprofit organizations and other partners. As rules were eased to speed support to the needy, the defendants allegedly produced invoices for meals never served, ran shell companies, laundered money, indulged in passport fraud and accepted kickbacks.

An Associated Press analysis published last June documented how thieves across the country plundered billions in federal COVID-19 relief dollars. Fraudsters potentially stole more than $280 billion, while another $123 billion was wasted or misspent. Combined, the loss represented 10% of the $4.3 trillion the government disbursed by last fall. Nearly 3,200 defendants have been charged and about $1.4 billion in stolen pandemic aid has been seized, according to the U.S. Justice Department.
