A former manager of an Iowa kosher slaughterhouse that was the site of a massive immigration raid was convicted Thursday on 86 financial fraud charges that could bring a prison sentence of hundreds of years.

Sholom Rubashkin still faces a second federal trial on 72 immigration charges.

Jurors returned the verdict against Rubashkin, 50, on their second day of deliberations after a nearly monthlong trial. Rubashkin had faced 91 charges, including bank, mail and wire fraud, and money laundering. He was found not guilty on five of 19 charges alleging he did not make timely payments to livestock dealers. A sentencing date was not immediately set.

"We respect the jury's hard work. It was a difficult case. We disagree with the verdict," defense attorney Guy Cook said after the decision. "There were many legal errors made by the prosecution in the trial of this case and following sentencing we will appeal."

Prosecutors offered no immediate comment and referred all questions to U.S. Attorney's Office spokesman Bob Teig, who did not immediately return a call seeking comment Thursday evening.

Prosecutors alleged that as a manager of the former Agriprocessors, Inc., plant in Postville, Iowa, Rubashkin intentionally deceived the company's lender. Former Agriprocessors employees testified that Rubashkin personally directed them to create fake invoices in order to show St. Louis-based First Bank that the plant had more money flowing in than it really did.

Cook argued Rubashkin never read the loan agreement with First Bank and tried to portray him as a bumbling businessman in over his head.

Rubashkin was detained after the jury was dismissed, despite a request from his defense team that he be allowed to remain free on bail. A hearing was set for Wednesday in Cedar Rapids, Iowa, to determine whether Rubashkin will be freed before his second trial, which is scheduled to begin Dec. 2.

The first trial was held in Sioux Falls after Rubashkin's attorneys requested a change of venue due to pretrial publicity. Continued...
