The burglary took place on October 10, after the man had gone to Costco and walked around before leaving, the partner reported. Hours later, he returned and the surveillance video of the store showed how the scheme unfolded.
"The suspect or culprit runs around hiding behind a display on the front wall of the store," said Robertson.
MPs say the man hid behind the shop sign for almost five hours and waited for the store to clear and shut down, the spokesman said. The staff said they had no idea that the man had stayed in the store after the closure.
He first entered the store, waited and left, before returning at 9:45. After midnight, they returned with a black ski mask and gloves, the authorities said. The video shows the man shattering a glass display and grabbing a handful of jewelery.
A video from a nearby theater shows the man running out of the store and returning to a truck.
