A tunnel that stretches from a former Kentucky Fried Chicken in Arizona all the way to a home in Mexico was discovered last week by investigators, who believe the secret passageway was used for drug smuggling, KSWT reports.
Earlier that day, Lopez was seen removing toolboxes from the old KFC. He is the owner of the building that once served as the fast food restaurant.
Agents executed a search warrant at the former restaurant and Lopez's residence. When investigating the old KFC, agents found the entrance of the tunnel in the kitchen area. It is eight inches in diameter, 22 feet deep and extended 590 feet long, HSI officials said. It ends at a residence in San Luis Rio Colorado, Sonora, Mexico.
At the Mexican side, the tunnel exited through a trap door underneath a bed. Authorities believe the narcotics being smuggled through the tunnel were being pulled up with a rope.
