Two human resource managers at Agriprocessors, the kosher meatpacking plant in Postville that was the site of a massive May 12 immigration raid, were indicted today by a grand jury.

Karina Freund, 29, of Fayette, and Laura Althouse, 38, of Postville, are now scheduled for arraignment Sept. 24.

Althouse, now formally charged with aiding and abetting document fraud and aiding and abetting aggravated identity theft, worked in the human resources department and had duties related to payroll at Agriprocessors, according to court documents. The original complaint stated that on May 11, the day before Immigration and Customs Enforcment raided the plant, Althouse was in the plant and helping employess complete new job-related documents and applications with newly acquired false identities.

If convicted on all charges, Althouse faces a mandatory minimum sentence of two years and a possible maximum sentence of 12 years in prison, a $500,000 fine, a special assessment of $200 and four years of supervised release.

Freund is now formally charged with harboring and aiding and abetting the harboring of undocumented aliens. The original complaint filed with the court alleged that she worked in the human resource department and that several undocumented alien employees at Agriprocessors have implicated her in helpng them obtain falsified documents.

If convicted, Freund faces a possible maximum sentence of five years in prison, a $250,000 fine, a special assessment of $100 and three years of supervised release.

Three other members of management at Agriprocessors have had complaints filed against them in federal court. Two of those cases resulted in plea bargains. The third complaint remains sealed while officials search for former plant supervisor Hosam Amara.

The company, Althouse, Freud and three other company officials — Aaron Rubashkin, Sholom Rubashkin and Elizabeth Billmeyer — face state charges on possible violation of child labor laws.
