Mollie Tibbetts case: Cristhian Bahena Rivera says two armed men put Tibbetts into his trunk, threatened him

The man charged with first-degree murder in the slaying of Mollie Tibbetts testified Wednesday that he didn't kill Tibbetts. Instead, he pointed blame at two unknown masked men — one armed with a gun, another with a knife — who surprised him at his home on the Yarrabee Farms property in rural Poweshiek County the night Tibbetts disappeared.

The men, according to Cristhian Bahena Rivera, forced him to get into his car July 18, 2018, and drive around near Brooklyn, Iowa, before spotting Tibbetts jogging toward town. Bahena Rivera said the men — one named "Jack" — made him circle around several times before stopping along a gravel road near where Tibbetts was last seen.

They drove out of Tibbetts' sight, Bahena Rivera testified. The man armed with the knife got out of the car for 10 to 12 minutes, while the other sat in the back seat.

Bahena Rivera told the jury he heard the man in the back seat mutter to himself while they awaited the other man's return to the car, including the phrase "come on, Jack." The man with the knife then returned, Bahena Rivera said, put something heavy in the trunk and told Bahena Rivera to drive them away.

The men, whom he'd never seen before that night, he testified, then threatened the safety of Bahena Rivera's family if he dared speak up, including his girlfriend and then-3-year-old daughter, and then allegedly ran off toward a gravel road.

Frightened, Bahena Rivera testified through an interpreter, he went to the car's trunk, found Tibbetts barely alive — but in such a state that he couldn't save her — then carried her into a cornfield where he laid her body down.

"She was very heavy ... I picked her up and I put her in the cornfield," he said, adding that he covered her with cornstalks. "I didn't want her to be too exposed to the sun."

She was still clothed in running shorts and a sports bra, but one shoe was off, he said.

"I left her (in the cornfield) exactly as she was in the trunk," he testified.

He testified that, after leaving her' body in the field, Bahena Rivera set Tibbetts' phone, Fitbit and earbuds along the side of the road before leaving the area.

Unsure where he was or how to get home, Bahena Rivera used his phone to get directions back to the trailer where he lived at the farm, he said.

Drastic turn in trial as it nears close

Cristhian Bahena Rivera testifies from the witness stand on Wednesday, May 26, 2021, at the Scott County Courthouse in Davenport, Iowa. Bahena Rivera is on trial after being charged with first-degree murder in the death of Mollie Tibbetts in July 2018.

Wednesday's testimony marks the first time that Bahena Rivera has publicly given a version of events from the night that Tibbetts was killed that differs from the hourslong statements he gave to police allegedly admitting to Tibbetts' murder a month after she went missing.

Bahena Rivera, 26, gave his version of events leading up to Tibbetts' death during about 45 minutes of direct examination by his attorney, Jennifer Frese.

His demeanor remained calm throughout his testimony, except when discussing his family. His voice dropped and trembled slightly as he described how the two men said “they knew Iris [Gamboa, his ex-girlfriend] and my daughter” and “that if I said something, they would take care of them.” His voice dropped again when he described why he told officers that he blacked out: “In my mind, I had my daughter,” he said.

While acknowledging he was in his black Chevrolet Malibu the night of Tibbetts' disappearance — the same car spotted on surveillance footage that authorities said broke open the case — Bahena Rivera claimed Wednesday that he was forced into the vehicle by the masked, armed men who showed up in his living room at his home at Yarrabee Farms.

The men — a large, heavier man and a smaller but muscular partner — surprised him at his trailer after he'd gotten out of the shower, Bahena Rivera testified.

After leaving Tibbetts' body in the field and finding his way home, Bahena Rivera said he never saw or heard from the men again.

Frese and her partner, Chad Frese, had previously tried shifting blame for Tibbetts' disappearance and death to a series of other men, including her boyfriend of three years, Dalton Jack. Jack, according to the state, was in Dubuque at the time working on bridge construction.

Defense attorney Chad Frese questions a witness during Cristhian Bahena Rivera's trial on Wednesday, May 26, 2021, at the Scott County Courthouse in Davenport, Iowa. Bahena Rivera is on trial after being charged with first-degree murder in the death of Mollie Tibbetts in July 2018.

Testimony a surprise in nearly two-week trial

Bahena Rivera's testimony, which took the court, including prosecutors, by surprise, came near the end of the nearly two-week trial, which is expected to last through Friday.

Most of the jurors were either slumped back in their seats or passively looking down through Wednesday's first three witnesses, including Jordyn Lamb, the woman with whom Jack had an affair during his relationship with Tibbetts. But many perked up when Bahena Rivera was called to the stand. Some leaned forward and took notes.

Bahena Rivera's version of Tibbetts' death seemed to come out of nowhere. Frese had been questioning Bahena Rivera about his background from Mexico and how he had arrived in the United States at 17 with the help of a “coyote” trafficker by raft with about 10 people being smuggled in illegally.

About 30 minutes into Frese's questioning, Bahena Rivera began telling his story.

“Mollie Tibbetts was in the trunk of your car, isn't that right?” Frese asked. “Yes,” he said, followed by Frese saying: “And you did not tell [investigators] what really happened. Isn't that right?”

“Correct,” Bahena Rivera said.

The story continues below.

He said his planned trip to Brooklyn the night of July 18, 2018, was to pick up a vacuum from his uncle's house to clean his car before going on a date the next day. But coming out of the shower about 6 p.m. after returning from his uncle's, the two masked men were standing in his trailer.

Bahena Rivera said he was compliant. "They said that I shouldn't do anything stupid, and everything was gonna be OK," he testified. "They're just, they're whispering, and we were there for a long while."

Asked by his attorney why he didn't notify anyone, Bahena Rivera said he didn't call police "because I was scared. ... If I called police, it was something that wouldn't be good."

Frese said: "You told not a soul about this for over a month. ... If you weren't approached, you would have taken this night with you to the grave, is that right?"

"Most probably," he answered. "Because I knew if I did in any way, I would be involved."

Prosecutor Scott Brown, who had stared at the defendant during Frese's questioning, grilled Bahena Rivera during cross-examination, reviewing all the opportunities he had to share what he knew with law enforcement.

When brought to the sheriff's office, Brown said, Bahena Rivera could have told investigators the truth and asked for their help in protecting his ex-girlfriend and their daughter.

As for the two men, Brown wanted to know how they got to Bahena Rivera's home, and how they left the cornfield, since Bahena Rivera did not see a vehicle at either location.

"And these two men just disappeared?" Brown asked.

"That is correct," Bahena Rivera said.

Defense questioned others Wednesday, too

The first witness, DCI agent Brandon Bublitz, said he made several trips to the area where Tibbetts' body was found to collect DNA and interview local residents.

DCI agent Matt George, who interviewed Jack several times during the investigation, said he asked for a second interview with Jack for "a complete outpouring of information" after learning Jack had had the affair. George testified Jack said Tibbetts knew he exchanged messages of a sexual nature with another woman but didn't know he'd had a physical affair with her.

If Tibbetts had known that, Jack allegedly told George, she would have broken off the relationship. The admission contradicted Jack's earlier testimony that Tibbetts knew all and had forgiven him.

Also testifying under subpoena from the defense was Jordyn Johnson, with whom Jack had admitted to having a brief affair before Tibbetts' disappearance. Johnson testified Wednesday that he texted her in early 2018 asking for another chance because he'd planned to break up with Tibbetts.

Johnson later shared those texts with Tibbetts, adding that Tibbetts was kind to her.

Bahena Rivera's testimony was next, followed by Jamie Slife, who called in several tips during the search for Tibbetts about her father, Ron Pexa, a 6-foot-7 former Tama County reserve deputy and police officer. The field where Tibbetts' body was found is adjacent to his property in rural Poweshiek County.

The final witness was Bahena Rivera's uncle, Luis Medina, who was among the family members to go to the Poweshiek County Sheriff's Office seeking information on Bahena Rivera the night he was arrested.

After he finished his testimony, the defense rested its case. Closing arguments are expected Thursday.
