Mollie Tibbetts' convicted killer sentenced to life in prison without parole

Mollie Tibbetts' convicted killer, Cristhian Bahena Rivera, is set to be sentenced Monday.

The 27-year-old man convicted of first-degree murder in the 2018 abduction and killing of University of Iowa student Mollie Tibbetts was sentenced on Monday afternoon to life in prison without the possibility of parole. Cristhian Bahena Rivera, an undocumented farmworker from Mexico, was sentenced after a victim impact statement from Tibbetts' mother, Laura Calderwood, was read in court by a victim advocate from the Iowa State Attorney General's Office. "I come here to give a voice to our daughter, granddaughter, sister, girlfriend, niece, cousin and friend, Mollie Cecilia Tibbetts," Calderwood wrote. "Mollie was a young woman who simply wanted to go for a quiet run on the evening of July 18 (2018) and you chose to violently and sadistically end that life." "Because of your act, Mollie's father, Rob, will never get to walk his only daughter down the aisle," she wrote. "Because of your act, Mr. Rivera, I will never get to see my daughter become a mother."
