IOWA (WOWK) — More than three years after Mollie Tibbetts disappeared while going for a jog in her hometown, the man convicted of killing her has been sentenced to life in prison without the possibility of parole.

Tibbetts, a University of Iowa student, was last seen alive on July 18, 2018, when she left her home in the town of Brooklyn to go for a run and never returned. A nationwide search was launched in the days after her disappearance but there was no sign of her for months.

Then, in August 2018, police used home surveillance video to identify a vehicle of interest that ultimately led them to Cristhian Bahena Rivera. In a police interview, he admitted to confronting Tibbetts during her run, and her responding by hitting him and threatening to call the police. The next thing he recalled was taking her body out of his truck and placing her in a cornfield. He led authorities to her body and was taken into custody.

An autopsy showed Tibbetts died of multiple stab wounds. Her DNA was discovered in the trunk of Rivera’s car. Rivera was convicted on May 28, 2021, of first-degree murder.

Rivera’s attorneys had requested a new trial for their client based on alleged confessions from an Iowa inmate who claimed Rivera may have been set up to cover for a sex trafficking operation. That request was denied.
