Calvin Duncan, 61, whose mailroom job included restocking office supplies at the Philadelphia Water Department, allegedly filed bloated orders for printer toner cartridges and ink since 2006 -- eventually totaling $1.3 million in unneeded purchases. He then sold them to alleged co-conspirators Derek and Anita Willis, owners of an Arkansas printer supply company who took the cheap toner and resold it at a markup, The Philadelphia Inquirer said Thursday.
Detectives said Duncan pocketed $545,000 in the scheme. The trio are charged with fraud and aiding and abetting. Because their scheme crossed state lines, it is a federal offense. The indictment doesn't specify how Duncan knew the Willises. The trio was arrested Wednesday.
