Border Patrol agents said that they spotted something unusual when they x-rayed the truck, which was driven by a 45 year old Mexican citizen. The truck’s manifest said that the load was made up of metal racks, but the suspicious agents called in a drug dog to assist.

When agents opened the truck’s trailer, they reportedly discovered 722 wrapped packages of marijuana stowed away in boxes. The combined weight of the packages is nearly 15,000 pounds. Officials say that the street value of the marijuana is around $8.6 million.

The truck driver’s visa was revoked and he was turned over to federal authorities.

The truck and the marijuana were seized.
