1 - 2: The Imposter: Dr. Barnes / Interstate Bank Mart Bandit

In case 1, for twenty years, Gerald Barnes faked being a doctor. He founded a successful practice that specialized in "executive" medical exams, earning a six-figure salary, despite not being the real Dr. Gerald Barnes. In case 2, the Interstate Bank Mart Bandit defrauded people out of their bank accounts, committing 43 robberies in 20 months with the same modus operandi and no evidence left behind.
