Authorities are still looking for a missing former Alabama prison officer and a murder suspect after the SUV they used to leave the jail yielded little new information in the case. Vicky White, 56, and inmate Casey White, 38, were believed to be driving in a 2007 Ford SUV when they escaped from the Lauderdale County Detention Center in Alabama more than a week ago, Sheriff Rick Singleton said at a news conference on Friday. “The car was cleaned out,” the sheriff told CNN Saturday. “There wasn’t anything left in the vehicle. They apparently took everything they had with them.”

On the morning of April 29, the prison officer, who is no longer employed by the sheriff’s office, left the jail with the inmate, claiming she would take him to the courthouse for a mental health evaluation. She also stated that after dropping him off, she would seek medical attention for herself because she was not feeling well. The pair failed to show up at the courthouse or medical institution, prompting a manhunt by local and federal authorities. Singleton has stated that the two are not related but may have had a romantic relationship.

“It’s been a trying, tough, disheartening week,” Singleton told CNN on Saturday. “As sheriff, I am ultimately accountable for the jail, and this falls on my shoulders.” “I want to see Casey White sent to prison, and I want Vicky White hauled in so we can figure out precisely what she was thinking,” Singleton continued.

Despite the fact that finding the SUV gave authorities a good idea of where the couple was going, detectives are still piecing together their actions days after they fled the jail in a patrol car.
