MONTEZUMA, Iowa (AP) -- Police say a man in the country illegally has been charged with murder in the death of Iowa college student Mollie Tibbetts.
A charge of 1st degree murder has been filed against 24-year-old Cristhian Bahena Rivera. If convicted, the charge carries a mandatory sentence of life in prison.
Investigators say they used surveillance video in tracking down Rivera. The video showed Tibbetts jogging in a rural area near her hometown of Brooklyn as well as Rivera's car.
Tibbetts, a 20-year-old student at the University of Iowa, was last seen July 18. Police had searched the area but noted her body was found in a field, covered with corn stalks.
