"Unraveling the mystery of Ritsche's millions” began with a tip about a civil lawsuit against Jack Amundson, a well-known certified public accountant who practiced for many years in the St. Cloud area. The lawsuit was filed by the daughter of Tom Ritsche, a successful businessman and philanthropist who died three years ago, and a local foundation. It accused Amundson of taking more than $5 million from a trust in Ritsche's name intended to benefit youth programs in St. Cloud.
