Dr. Martinez was born and raised in southwest Chicago, so he was thrilled to accept a position teaching at the University of Chicago in 2005. Shortly thereafter, Dr. Martinez received a letter from the IRS that stated he failed to pay taxes on wages earned the previous year in Colorado; the letter arrived with a substantial bill. Although Dr. Martinez had never worked in Colorado, someone using his name, SSN, and date of birth had received wages there from a facilities management company. Dr. Martinez then had to go about proving his case to the IRS, tracking down credit reports, bank records, and cell phone accounts, all while searching for a person who was working under a common Hispanic name.
