Icy roads contributed to several accidents Sunday morning, in Cass County. A van carrying 10 people rolled into a ditch near exit 60 (Hwy 71). The accident happened at around 8:30-a.m.  At least one person suffered serious injuries and was transported to the Cass County Memorial Hospital in Atlantic. Eight people were later turned over to officials with the Immigration and Customs Enforcement (ICE) agency. Two adult individuals in the van who were initially reported as missing, are believed to have caught a ride to Omaha, and were being sought for questioning.
