Cristhian Bahena Rivera will be sentenced Monday afternoon (8/30) for killing Mollie Tibbetts.  In May, a jury in Scott County found the 27-year-old Bahena Rivers guilty of first degree murder in the July 2018 death of Tibbetts.  She disappeared while jogging in her home town of Brooklyn.  Her body was found in a cornfield a month later.  Bahena Rivera is expected to be sentenced to life in prison.  That sentence will be announced Monday afternoon in Montezuma.
