But, he added, Mendoza Olmos may have left on her own accord.

The search, now going on for nearly a week, has turned up scant clues, primarily a video believed to be of her recorded the day she disappeared. Surveillance footage shows a woman searching in the back of her car for an unknown item, the sheriff’s office said.

Authorities believe she then walked somewhere, because her car was left behind.

The only items she had on her, authorities said, were her car keys and possibly her driver’s license. They were concerned that she left her phone behind, which was unusual.

Sheriff Salazar also told ABC News that Mendoza Olmos, who is a US citizen, was not detained by Immigration and Customs Enforcement (ICE), which has been conducting sweeps of suspected illegal immigrants throughout the country.

“That was a personal concern. So, I had it checked to make sure that there were no stops, no detentions, and that she’s not somewhere in a federal detention facility,” Salazar told the outlet.

Authorities have deployed deputies, investigators, search-and-rescue resources and teams, drones, and cadaver dogs in the search for Olmos, the sheriff’s office said.

FBI officers have also been helping out local law enforcement, Sheriff Javier Salazar told CBS.

“Cami needs us,” her aunt, Nancy Olmos, wrote on social media. “By the grace of Jesus Christ, we will find you, Cami.”
