The former Iowa school district superintendent detained by immigration authorities last week has been taken into custody by the Justice Department. Ian Roberts, who led Des Moines Public Schools (DMPS), was no longer in the custody of the Woodbury County Jail in Sioux City, about 150 miles northwest of Des Moines, Sheriff Chad Sheehan said. Roberts was taken into federal custody on an arrest warrant and made his first court appearance, the Justice Department said. Federal prosecutors said Roberts, 54, was found with four firearms on Sept. 26 while living in the country illegally.
