Plymouth Township’s William Street Jr. understood what identity theft was before the term was invented or coined. The 64-year-old con man spent four decades for his impersonations of other people, including a doctor, a lawyer, a football player, and even fooled the Detroit Tigers into giving him a tryout in the early 1970s. Last September, Street pled guilty in Detroit Federal Court to a charge of mail fraud and identity theft. The case involved him stealing the identity of a Defense Department contractor so he could get a job. Streets 46-year criminal career now includes 25 convictions. He faces up to three years in prison in his new identity as an inmate.
