It has been learned that Cristhian Rivera had worked at Yarrabee Farms for the last four years and was an employee in good standing. The company said it was shocked to hear that Rivera had been charged in the death of 20-year-old Mollie Tibbetts.  The farm is owned by Craig Lang, who previously served as president of the Iowa Farm Bureau and president of the Iowa Board of Regents, which governs the state’s public universities. In June, he lost a close GOP primary in the race for state agriculture secretary.

And Immigration and Customs Enforcement released a statement Tuesday stating that it had “lodged a detainer” with the Poweshiek County sheriff’s office to hold Rivera after he was charged with first-degree murder.
