Remy Lewis has just started working as a marketing research analyst for Commercial Casting Company in New York City. He is relocating his family to New York from North Carolina, but they haven't moved yet. Twice a month, the company pays for Lewis to travel to North Carolina to visit his family and help with the move. During the month of September, Lewis only visited his family once; however, he submitted expense reports for mileage for two separate trips to North Carolina and back. What type of fraud scheme is involved and why?
