GRAY, Tenn. -

Detectives say the woman who held up a Gray, Tennessee restaurant Wednesday afternoon made a bold move.

The cameras were rolling as she walked into the China Luck Buffett, pulled out a gun, then emptied the cash register.

"With the restaurant they gave us some really good video,” says Washington County, Tennessee Sheriff’s Department Captain Shawn Judy,. “[WCYB] aired it, gave us good leads which we are following up on."

Detectives believe the woman is the same person who held up a Little Caesar’s Pizza in Johnson City earlier this month.

Susie Dvorak owns the consignment store next door to China Luck Buffett. She told us Wednesday's robbery has her worried. "I was nervous when it started getting dark," says Dvorak.

Detectives say the key to solving the restaurant robbery may be the video. Officers say other stores should check their systems and make sure they are working.

Cameras are always recording activity inside Kaleidescope Consignment.

Dvorak said the investment was a must when she opened the doors. “They are more about inventory control,” said Dvorak. “I've never given much thought of them being used if anybody held me up."

Without working video officers are left with only witness descriptions, which they say are not reliable.

They are also encouraging owners to be proactive and train staff what to do in case of a robbery. "Store owners should put a list together next to the cash register,” says Captain Judy. “So if something happens, there is a checklist there."

He says it should include reminders to write down descriptions and any vehicle information, but officers say workers should not chase after a robber.
