Four meatpacking workers at the Cargill Meat Solutions plant in Dodge City are facing aggravated identity theft charges.
The four Mexican citizens made initial appearances Monday in U.S. District in Wichita on charges that they fraudulently used the names and Social Security numbers of others to work at the plant.
The complaint says the arrests came after agents from the U.S. Immigrations and Customs Enforcement went to the men's homes on Feb. 18. Agency spokesman Carl Rusnok says investigators were following a lead provided by the Federal Trade Commission.
Agents also used a two-year-old immigration audit of Cargill employment records in their probe.
The defendants are Leonardo Leon-Flores, Rogelio Gomez-Bernardino, Ramiro Santos-Carreto and Alejandro Cruz-Flores.
