A convicted swindler who is a key player in a $50 million nationwide investment scam has been selling "reverse mortgages" to senior citizens in the Spokane area while he awaits a date to report to prison. Michael Duane Smith has worked as a "reverse mortgage planner" for Golf Savings, a subsidiary of Spokane-based Sterling Savings, according to a brochure touting the loans, which are geared toward older homeowners. "He no longer works here," Sterling spokeswoman Jennifer Lutz said Tuesday. She and other senior officials with Sterling and Golf declined to answer other questions, including why a felon would be working for a lending institution.
