The manconvicted of abductingand murdering 20-year-old University of Iowa studentMollie Tibbettsin 2018 has been sentenced to life in prison.
“I come here to give a voice to our daughter, granddaughter, sister, girlfriend, niece, cousin and friend, Mollie Cecilia Tibbetts,” Calderwood wrote, according toABC News. “Mollie was a young woman who simply wanted to go for a quiet run on the evening of July 18 and you chose to violently and sadistically end that life.”
The last time anyone saw Tibbetts alive was around 7:30 p.m. on July 18, 2018, while jogging in Brooklyn, a community of some 1,500 people in eastern Iowa, authorities said.
Tibbetts had been dog-sittingbut headed out for some exercise as part of her typical routine, according to her boyfriend, Dalton Jack.
Bahena Rivera made several admissions following his arrest. After initially saying he only recognized Tibbetts' face from missing posters,he later told police he had in fact seen her jogging.
He said he considered Tibbetts attractive, and, after driving passed her, circled back to get a second look at her.
Prosecutors said Bahena Rivera told police he pulled over and jogged up to Tibbetts, trying to talk to her. She rebuffed his advances, even threatening to call the police, he told detectives.

He said he recalled placing her in the trunk of his car and, later that evening, drove to a remote field where he left her body face up beforecovering it with corn stalks.
Prosecutors said Tibbetts was “decomposed beyond all recognition” when she was found in late August 2018.

Bahena Rivera worked at a dairy farmless than three miles from where Tibbetts was seen running the night she vanished. A Mexican immigrant, Bahena Rivera, who was 24 at the time of the murder, had been working at the farm for four years under a fake name.
During his trial, Bahena Rivera testified in his own defense, telling jurors two armed men in masks forced him to help them kidnap Tibbetts.
According toNBC News, on Monday Judge Yates rejected his claims, telling the 27-year-old, “You, and you alone, forever changed the lives of those who loved Mollie Tibbetts. And for that, you and you alone will receive the following sentence.”
