IOWA CITY, Iowa — A man was sentenced to life in prison Monday in the stabbing death of University of Iowa student Mollie Tibbetts, three years after she disappeared while out for an evening run.
Judge Joel Yates sentenced Cristhian Bahena Rivera to life without the possibility of parole, the mandatory sentence for first-degree murder in Iowa, which does not have the death penalty. The 27-year-old former farmhand, who testified that he came to the U.S. illegally from Mexico as a teenager, has been jailed since his arrest in August 2018.
The sentence caps a case that inflamed anger over illegal immigration, fueled fears about random violence against solo female joggers, and took several noteworthy twists during and after Bahena Rivera’s trial in May.
At the center of the case was Tibbetts, 20, who was remembered as a kind and bright young woman who was quick to help others and planned a career in child psychology.
She vanished on a rural road outside her hometown of Brooklyn, Iowa, population 1,700, while out for one of her near-daily runs on July 18, 2018. Bahena Rivera led investigators to her body a month later.
Family members and co-workers feared something was wrong when Tibbetts did not show up for her summer job at a daycare the next morning.
Hundreds of volunteers and law enforcement officers searched for her for weeks but came up empty. Investigators say they began focusing on Bahena Rivera, who worked under an alias at a nearby dairy farm, after finding a homeowner’s surveillance video showing his Chevy Malibu appearing to repeatedly drive past Tibbetts while she ran.
After a lengthy interrogation, Bahena Rivera led authorities to a field where he had buried Tibbetts’ body under leaves and stalks. Only her bright running shoes were visible. An autopsy found she had been stabbed several times.
Bahena Rivera told investigators that he approached Tibbetts because he found her attractive, and that he fought with her after she threatened to call the police. He said he then blacked out and came to as he was driving with her body in his trunk.
Prosecutors suggested Bahena Rivera had a sexual motive, noting Tibbetts was wearing only socks and a sports bra and that her legs were spread when her body was found. They built their case around the surveillance video, his partial confession and DNA evidence of Tibbetts’ blood in his trunk.
Bahena Rivera’s lawyers argued his confession was false and had been coerced, and their client gave surprise testimony at trial sharing a different account. Bahena Rivera testified that two masked men kidnapped him from his trailer at gunpoint, made him drive while they attacked Tibbetts, instructed him on where to dispose of her body, and told him to stay quiet or that his young daughter and ex-girlfriend would be killed.
The defense sought to cast suspicion on several others who had been scrutinized by investigators, including Tibbetts’ boyfriend and a local deputy who lives next to where Tibbetts’ body was found.
Prosecutors called Bahena Rivera’s testimony a work of fiction and a unanimous 12-member jury found him guilty.
But two people immediately came forward to tell police that a 21-year-old man with a history of violence had confessed to them that he had killed Tibbetts. Other information surfaced showing that a woman had told police she had been kidnapped after meeting an alleged sex trafficker at a Brooklyn gas station weeks before Tibbetts’ disappearance.
Yates delayed a July sentencing so the defense had time to investigate. Earlier this month, he denied Bahena Rivera’s motion for a new trial, saying the new information was unreliable and he saw no reason to overturn the jury’s verdict. The defense plans to appeal.
