Paula’s boyfriend moved to her home town, Oklahoma City, from Houston, Texas. Two weeks after he arrived, he asked her to phone his bank in Houston and inquire about his balance. She did so as a favor to him and found out the balance was more than $40,000. As soon as she told him, he left and drove to Houston to remove it from his account. In Houston, he was arrested by the FBI for fraud and several related crimes. Paula was then charged with the federal crime of making a phone call across state lines for the furtherance of a fraudulent scheme. Her boyfriend only knew the scheme had been successful by Paula’s report of the large balance in his old account. What would be a possible defense for Paula?
