View Comments The judge who will oversee the trial of murder suspect Cristhian Bahena Rivera said Thursday he will reserve judgment on many of the evidentiary issues raised by both the prosecution and the defense. Bahena Rivera will stand trial beginning Monday for the 2018 murder of Mollie Tibbetts, a 20-year-old University of Iowa student whose disappearance while jogging near her home in Brooklyn, Iowa, set off a massive search effort that drew national attention. Police have said that he admitted to encountering and chasing her on her run, and that he led them to where her body was found hidden in a cornfield.
