Although identity theft is one of the fastest growing economic crimes in the United States, researchers have devoted little attention to understanding identity thieves. Basing their work on interviews with 59 inmates serving time in federal prison for a variety of identity theft crimes, Copes and Vieraitis use criminological and sociological theories to gain insight into the cognitive, behavioral, and organizational aspects of identity theft. They also offer policy recommendations to reduce the ever-increasing threat of this crime.
