The mother of a corrections officers who vanished with an Alabama inmate suspected of capital murder says she is scared for her daughter.

“We don’t know if she was took by force or if she was voluntarily in this. But we just want her back, that’s all we want,” Pat Davis said about her daughter and correction officer Vicky White.

The search continued Monday for Vicky White and Alabama inmate, Casey Cole White, 38, who vanished after leaving a county jail.

The pair departed the Lauderdale County Detention Center in Florence, Alabama, on Friday morning and have not been seen since.

Casey White was scheduled for a trial next month on a capital murder charge. Vicky White, the assistant director of corrections at the facility, told co-workers she was taking the inmate to the courthouse for a mental health evaluation. The sheriff later told reporters that no such evaluation was scheduled.

“Casey White is believed to be a serious threat to the corrections officer and the public,” U.S. Marshal Marty Keely said in a statement on Sunday. The U.S. Marshals Service is offering up to $10,000 for information.

The pair are not related, the sheriff said. The sheriff’s office has scheduled a press conference late Monday morning.

The vehicle the officer and the inmate were in when they left the detention center was found at a nearby shopping center parking lot, according to the sheriff’s office.

Casey White was already serving a prison sentence for attempted murder and burglary and is accused of stabbing a 58-year-old woman to death. He stands 6 feet, 9 inches (2.06 meters) tall and weighs about 260 pounds, according to the U.S. Marshals Service. He has brown hair and hazel eyes.

Authorities said they are investigating if the officer played a role in the escape by coercion or voluntarily. She cited a courthouse appointment that did not exist when she left the jail with the inmate, and broke department rules by escorting the murder suspect alone.
