Martin De La Rosa-Loera, a former supervisor at Agriprocessors Inc., in Postville, Iowa, was sentenced Wednesday to 23 months in federal prison for aiding and abetting in harboring illegal aliens. The U.S. District Court Chief Judge increased Mr. De La Rosa-Loera’s sentence from the sentencing guidelines because he held a supervisory position, and also because 100 or more illegal aliens were harbored. According to information presented in court, Mr. De La Rosa-Loera became a permanent resident in 2002 and later became a naturalized U.S. citizen. Mr. De La Rosa-Loera supervised approximately 70 employees at Agriprocessors. In May 2007, he told his employees that they would need to change their Social Security numbers and names in order to continue working at the company. He also told them that would have to resume work at a lower wage of $6.25 per hour. Between 100 and 200 workers walked off the job in protest after this occurred. In April 2008, Mr. De La Rosa-Loera received a list of several employees who were to be terminated. Although Mr. De La Rosa-Loera was told the Social Security numbers of these particular employees were not valid, Mr. De La Rosa-Loera's supervisors told him six of the most valuable workers could stay if they got new identification documents. Mr. De La Rosa-Loera directed a leadperson under his supervision to get new identification documents, and directed the leadperson to tell five other employees on the list to do the same. The company's human resources director later determined the employees' new fake documents were not valid. Nevertheless, the six employees were allowed to continue working at Agriprocessors under their old documents. Subsequently, in October 2007, the U.S. Immigration and Customs Enforcement began investigating Agriprocessors. The investigation is ongoing.
