Authorities on Monday continued the hunt for an “extremely dangerous” murder suspect and issued an arrest warrant for the Alabama jail official they now believe helped him escape.

Inmate Casey Cole White, 38, was shackled and handcuffed when he and Vicky White, the facility’s assistant director of corrections, left the Lauderdale County Detention Center in Florence, Alabama, on Friday morning. They have not been seen since, although the patrol vehicle that the pair used when leaving the detention center was found at a nearby shopping center parking lot after their absence was discovered.

Authorities have no idea where they are, although the inmate should be recognizable by his size. He stands 6 feet, 9 inches (2.06 meters) tall, and weighs about 260 pounds (118 kilograms). Authorities warned that anyone seeing the pair should not approach them.

“We consider both of them dangerous and, in all probability, both individuals are armed,” U.S. Marshal Marty Keely said at a press conference Monday. He noted that Casey White “will stand out” because of his size, even if he has changed his appearance.

Lauderdale County Sheriff Rick Singleton said Monday that they had issued an arrest warrant for Vicky White, 56, on charges of permitting or allowing an escape. She is not related to Casey White, who was serving a 75-year prison sentence and awaiting trial on a capital murder charge.

Vicky White told co-workers she was taking him to the courthouse for a mental health evaluation. But Singleton later said no such evaluation was scheduled. She also violated a policy that required more than one official to be involved in transporting inmates, a rule that officials emphasized for White because he had previously tried to escape, Singleton said. The sheriff said the video showed the pair left the jail and went straight to that parking lot.

“We know she participated, whether she did that willingly or if she was coerced, threatened somehow to participate, not sure. We know for sure she did participate,” Singleton said.

“Casey White, as you’ve heard me say over and over and over is an extremely dangerous person and we need to get him located and get him off the street,” Singleton said.

Casey White was serving time for a string of crimes that included attempted murder, robbery, and burglary. While in prison, he had confessed to the 2015 stabbing death of a 58-year-old woman, authorities said, which caused him to be brought to the Lauderdale County jail for court proceedings. The sheriff said they believe White plotted an earlier escape from the jail in 2020 when they found a makeshift knife.
