C.B.P. agents found a number of anomalies in a 1997 Jeep Wrangler that was crossing into the United States at the Presidio Port-of-Entry around 11 PM on January 28th, and agents flagged the vehicle for an extensive search.
Agents were draining oil from the vehicle's oil pan when they found 3 cocaine-filled packages in the pan.
The packages -- which tested positive for cocaine -- weighed a combined 7.48 pounds.
The driver of the Jeep -- Ricardo Zavala Espinoza of Chihuahua City, Chihuahua, Mexico -- was arrested after the failed smuggling attempt.
Espinoza, 34, was turned over to U.S. Immigration and Customs Enforcement Homeland Security Investigations agents during his arrest.
