GRAND JUNCTION, Colo. -- A Grand Junction-based grocery store chain said it will look into how a company that performs background checks on employees at its stores reported that a new hire had used drugs with cartoon characters.

Sue Jones was placed on administrative leave and missed several days of work at City Market after South Carolina-based General Information Systems reported the alleged drug use and flagged her as a "do not hire."

The report also erroneously indicated she had previously been charged with felony drug possession and misdemeanor gambling.

Grand Junction's KKCO-TV reported the date of birth on the criminal court cases did not match the real Sue Jones, nor was there a Social Security number to tie them to her.

The court cases cited by G.I.S. listed the other defendants as Porky Pig, Bugs Bunny and Elmer Fudd. The station reported that they were phony test cases -- practice for people working in the court system, using arbitrary names such as "Sue Jones."

G.I.S. executive David Bartley declined comment on the report.

Jones has returned to work at City Market after disputing the G.I.S. report. She said she has never done drugs or gotten any more than a traffic ticket.

City Market wouldn't say whether it would continue to use the company to conduct its background checks.
