The Arizona Republic reports that a federal judge on November 21 sentenced Danny Hendon, who formerly owned and operated the Phoenix, AZ-based Danny’s Family Car Wash chain, to 12 months and one day in prison and 12 months of home detention for his role in an illegal hiring scheme that federal agents shut down last year.

According to the report, a Department of Homeland Security (DHA) audit in March 2011 revealed 942 wash employees had not presented sufficient work authorization documents at the time they were hired. The company informed DHA that those employees had been terminated, but then rehired the undocumented workers. The scheme involved hundreds of instances where documents were falsified, identities were stolen, and false statements were made under penalty of perjury.

Hendon, who had earlier agreed to divest himself of the company, was given a self-surrender date of January 20.
