(CNN) — The man accused of pursuing and killing 20-year-old Mollie Tibbetts will make his first court appearance at 2 p.m. ET Wednesday to face a charge of first-degree murder, the Poweshiek County Clerk’s office said.
The court hearing for Cristhian Bahena Rivera comes a month after Tibbetts went for an evening run in Brooklyn, Iowa, and did not return home. On Tuesday, Rivera — who confessed to following her as she ran on a country road — led authorities to the field where a body believed to be hers was buried under corn stalks, officials said.
While authorities have yet to confirm the body is hers, they arrested Rivera, 24, on first-degree murder charges. Charges were filed in district court in Poweshiek County and bail was set at $1 million.
Rivera, a Mexican man who officials said came to the US illegally, told investigators that he saw her and got out of his car. He ran beside Tibbetts — even after she warned him she would call police, officials told reporters Tuesday.
The suspect alleged he blacked out at some point, and that when he came to, he realized he had put the woman in the trunk of his car. Rivera led authorities to a corn field on Tuesday morning, where they found a body covered in corn leaves. Tibbetts’ clothing was also found at the scene.
It is unclear why Rivera killed Tibbetts, said Rick Rahn, special agent in charge at the Iowa Division of Criminal Investigation.
“I can’t really speak to you about the motive,” Rahn said. “I can just tell you it seems that he followed her and seemed to be drawn to her on that particular day and for whatever reason he chose to abduct her.”
An autopsy to determine when and how Tibbetts died is planned for Wednesday.
A month-long search
Tibbetts was studying psychology at the University of Iowa and wanted to get a doctorate and write books, her father said. Her disappearance set off an extensive search that brought in hundreds of leads but no clues as to where she was.
Authorities had been looking for Tibbetts for about a month when they found home surveillance video that showed a car following a woman running on July 18.
After watching it for hours, investigators found clues that led them to Rivera. He didn’t resist when authorities tried to detain him, Rahn said.
According to court documents, the suspect said in an interview that when he approached Tibbetts, she pulled out her cell phone and told Rivera she was going to “call the police” and that caused him to get angry.
He said he blacked out and woke up at an intersection in rural Poweshiek County, court documents say.
Rahn said the suspect told investigators he realized he had put the woman in the trunk of his car and when he took her out, he saw blood on the side of her head, the document says. He left the body in a cornfield and covered it with corn leaves, it adds.
In addition, Rahn said Tibbetts’ digital footprint, which included data from a fitness tracker known as a Fitbit, played a role in solving the case.
Suspect came to US illegally
Shawn Neudauer, a spokesman for Immigration and Customs Enforcement, said the agency on Tuesday sent a detainer request to local authorities for Rivera, who is from Mexico. That means ICE could take custody of Rivera if he was released from local custody.
Authorities believe the suspect has been in the area for four to seven years, Rahn said.
He worked at a dairy farm that is owned in part by Craig Lang, a prominent Iowa Republican who ran for secretary of agriculture this summer, CNN affiliate WHO reported.
In a statement to WHO, the company, Yarrabee Farms, said Rivera was vetted through the government’s E-Verify system and was an employee in good standing.
“First and foremost, our thoughts and prayers are with the family and friends of Mollie Tibbetts,” it said. “This is a profoundly sad day for our community. All of us at Yarrabee Farms are shocked to hear that one of our employees was involved and is charged in this case.”
Rivera’s immigration status was cited by Republican leaders to argue for a change in American immigration policy. President Donald Trump referred to the case while speaking at a rally in Charleston, West Virginia on Tuesday night.
“You heard about today with the illegal alien coming in very sadly from Mexico. And you saw what happened to that incredible beautiful young woman. Should have never happened. Illegally in our country,” he said.
“We’ve had a huge impact but the laws are so bad, the immigration laws are such a disgrace. We’re getting it changed but we have to get more Republicans.”
