An Atlanta man used a storage unit near Buford to hide 15 kilos of cocaine worth nearly $1.5 million, authorities told the Gainesville Times.

Robert Perez-Mendoza, 32, was arrested and charged with trafficking cocaine and possession of cocaine with intent to distribute, according to the newspaper. He’s being held in the Hall County Jail.

An officer in Hall County’s Multi-Agency Narcotics Squad was training with his police dog this month at the mini-storage facility “when the dog indicated on a certain unit,” the squad’s commander, Lt. Scott Ware, told the paper. “We obtained a search warrant and found the 15 kilograms inside.”

“Our K-9 officer trains his dog throughout Hall County in different environments, and we got lucky on this one,” Ware added.
