CORRECTION: Searchers were sent out Thursday to areas around San Bernardino and Redlands. A previous version of this story incorrectly reported the status of the physical search.

Police continued searching Thursday, March 12, for a San Bernardino woman who has been missing since Monday, as well as examining the clues they have gathered.

Investigators worked through the night Wednesday interviewing people, re-interviewing people and following up on leads, said San Bernardino police Lt. Rich Lawhead.

“We’re continually getting more leads,” he said.

The clues uncovered so far don’t “point in any one direction,” so whether 22-year-old Sahray Astina Barber was taken or voluntarily went missing are both possibilities, Lawhead said.

“We’re looking at this thing from every angle,” he said.

On Thursday, search teams examined Little Mountain and Devil’s Canyon in northern San Bernardino as well as undeveloped areas near Redlands on foot, on horseback and with off-road vehicles, Lawhead said.

Barber was last seen about 6 a.m. Monday when she left her apartment just across the street from Cal State San Bernardino to go to class at the Art Institute of California-Inland Empire, where she is a student-worker studying graphic design, police said.

Both police and Barber’s parents say to suddenly disappear is not like her, and concerns are heightened because in the week prior, an attempted kidnapping and attempted rape were reported at CSUSB.

Police have not determined whether the attacks and Barber’s disappearance are related.

She normally takes the bus to school. She never boarded the bus that morning, never arrived at school, and has not been seen since, police said. Family members reported her missing Monday evening.

Investigators found Barber’s laptop and cellphone in bushes near her apartment. While Lawhead said this is certainly suspicious, it doesn’t necessarily indicate anything illegal occurred.

“Obviously somebody doing something out of their normal character is worrying,” he said.

Lawhead has said no one heard or saw anything to suggest a struggle took place where Barber’s belongings were discovered, and no physical evidence to that effect was found.

On Tuesday and Wednesday, search teams on horseback and on dirt bikes combed the wild areas north of Barber’s home looking for clues – flattened grass, vehicle trails – and a helicopter scanned the area from the sky.

Officers also scoured the area with bloodhounds to no avail.

San Bernardino Mayor Carey Davis released a written statement Thursday to “assure the students at CSUSB, the Art Institute of California-Inland Empire and (city) residents that we are tirelessly working on this investigation.”

He encouraged people to be aware of their surroundings and not to travel alone.

“This is a time for our community to band together and show these individuals that this will not be tolerated,” he wrote.

Anybody with information about Barber’s whereabouts is asked to call Detective Dan Han at 909-384-5623 or the detective’s bureau at 909-384-5615.
