Cristhian Bahena Rivera, 24, is facing first degree murder charges for the death of Iowa college student Mollie Tibbetts.
Mollie disappeared after going for a run on the evening of July 18, and was reported missing after she failed to show up for work the next day.
Authorities say a body was found in a farm field in the early morning hours of August 21, with Rivera acting as a guide for investigators. The body, believed to be Mollie, was covered by corn stalks. Source
