DEL RIO, Texas - U.S. Customs and Border Protection agents said they are "praising their canine counterparts" after they alerted officers to a hefty amount of narcotics nearly smuggled into the United States.

In two separate incidents that happened just a few hours apart, CBP officers assigned to the Del Rio International Bridge discovered narcotics hidden in two vehicles crossing from Mexico on June 9.

The first discovery yielded 4.95 pounds of alleged methamphetamine in a 1996 Mercury van with a street value of $69,352.

The second discovery yielded 59 pounds of meth in a 2011 Dodge Avenger with a street value of $828,400.

“Our CBP officers are vigilant professionals, constantly on the lookout for illicit activities. These seizures represent a significant amount of contraband that will not make it into our communities,” Del Rio port director Alberto D. Perez said.

Both vehicles, as well as the driver of the Avenger, who is a United States citizen, were turned over to Homeland Security Investigations, or HSI, for federal prosecution.

The alleged narcotics were also confiscated for further testing and will be used as evidence.
