Investigators say she believes the man was driving some kind of white work van with a magnetic sign on the driver's side door. The van appeared to be brand new.
The victim also remembers the license plate started with the numbers "911," but she doesn't remember the state.
Police are still hoping the public can help solve the case. If you have any information, you're urged to call the West Virginia State Police at (304) 824-3101.
Linda Casey says the suspect released the worker a short time later unharmed.
The incident happened at about 2:30 a.m. at the Speedway on Route 10.
West Virginia State Police say the man walked in wearing a camouflage bag over his head with a Halloween wig and was holding a gun in his right hand. He demanded cash, but the clerk didn't immediately comply-- so he took her out to his van where he handcuffed her and told her to take off her clothes.
Investigators say the suspect then drove the woman about two miles north on Route 10 before she convinced him to let her go. He let her out on the side of the road with her clothes, and she flagged down another car to get a ride back to the gas station.
The victim was able to tell troopers that the person who took her was a man about 275 to 300 pounds driving a white van. The license plate may have the numbers "911" on it. He was last seen driving south on Route 10.
Casey says the company will offer the worker counseling and any other assistance she needs to get through this difficult time. She hopes someone in the community comes forward with information to help police arrest this man.
