Authorities charged four suspects on June 1 with felony drug distribution violations after finding a hidden tunnel used by drug runners inside a retail store in San Diego County that led into Tijuana, Mexico.
Investigators also seized more than a ton of cocaine worth about $45 million in connection with the subterranean tunnel, according to the U.S. Attorney’s Office and the U.S. Homeland Security’s Tunnel Task Force in charge of the operation.
