Cristhian Bahena Rivera​: Arrest of undocumented immigrant in Mollie Tibbetts' slaying may play into 2018 race With two words, the lead investigator in the death of a 20-year-old Iowa college student may have ratcheted up the debate over illegal immigration going into the last three months of the 2018 midterms. During a news conference Tuesday, Iowa Division of Criminal Investigation Special Agent Rick Rahn said the man accused of killing Mollie Tibbetts, who went missing in July while jogging in Brooklyn, Iowa, is an "illegal alien." Immigration and Customs Enforcement (ICE) confirmed that Cristhian Bahena Rivera, 24, is an undocumented immigrant from Mexico.
