Half-mile tunnel found on US-Mexico border, cocaine seized

SAN DIEGO (AP) — U.S. authorities said Wednesday that they discovered a cross-border tunnel that ran a half-mile from a Tijuana house equipped with a large elevator to a lot in San Diego that was advertised as a wooden pallet business, resulting in seizures of more than a ton of cocaine and seven tons of marijuana.

Tunnels are often built for marijuana because its bulk and odor make it more difficult to escape border inspectors' scrutiny than cocaine and other drugs.

Authorities saw a trash bin forklifted on to a truck at the San Diego lot on April 13 and followed it to a parking lot in San Diego, a U.S. Immigration and Customs Enforcement Homeland Security Investigations investigator said in a criminal complaint.

The San Diego-Tijuana region is popular because its clay-like soil is relatively easy to dig with shovels and pneumatic tools, and both sides of the border have warehouses that provide cover for trucks and heavy equipment.
