The owners of a Knoxville, Tenn., Jewelry store said they were the victim of an overnight heist that netted up to $1 million in jewelry, according to media reports.

Janice Enix, wife of Enix Jewelers president William Enix, said that sometime after 11:30 p.m. Dec. 6 two suspects cut through the store’s roof and dropped inside the building, the Knoxville News Sentinel reports. The thieves then cut the wires to the security system and proceeded to use one or more torches to cut their way into the store’s safe.

Enix said that Knox County Sheriff’s Office detectives found two sets of footprints at the scene and are reviewing footage from video cameras that might have caught a glimpse of the suspects.

An employee discovered the theft shortly after 9 a.m. while preparing for the 10 a.m. opening of the store, which is at 6927A Maynardville Pike, the newspaper reports.

The employee grew concerned when the sound of the store alarm was not emitted when the employee entered, the newspaper reports.
