Divers off Key West, Florida, stumbled upon an unexpected find while exploring the ocean floor. What initially appeared to be trash turned out to be more than two dozen packages of suspected cocaine, authorities confirmed on Wednesday.

The Monroe County Sheriff’s Office reported that scuba divers from the Rainbow Reef Dive Center in Key Largo initially believed they had encountered garbage. However, upon closer inspection, they discovered packages marked “Nike SB,” complete with counterfeit swoosh logos.

Officials revealed that the 25 packages, each weighing about a kilogram (2.2 pounds), were found approximately 100 feet underwater in the Atlantic Ocean. The suspected drugs have since been handed over to the U.S. Border Patrol.
