DES MOINES, Iowa -- Court records show details of why a manager at a meatpacking in Marshalltown was charged with aiding illegal immigrants this week.


According to records, immigration officials recorded Christopher Lamb as he coached an illegal immigrant on how to apply for a job using a fake name and documents.


Lamb is a human resources manager for Swift and Co., which had 20 people arrested this week by federal agents at plants across the country.

It was part of the ongoing investigation into identity theft and illegal employment of workers. Lamb is among four arrested at the Marshalltown plant Tuesday.
