Court documents describe how the investigation led by the FBI and U.S. Postal Inspection Service came out of a 2016 Minnesota Attorney General's Office lawsuit against Wayne R. Dahl Jr., a 51-year-old Fridley man whose Your Magazine Service, Inc., was later ordered by a judge to pay $20 million. Dahl has also since pleaded guilty to running a decadelong scam that defrauded at least 13,000 people out of $11 million.
