SAN DIEGO (KGTV) -- Nearly 140 pounds of liquid methamphetamine and two pounds of heroin were discovered inside a vehicle’s gas tank and spare tire at the Otay Mesa Port of Entry Monday, U.S. Customs and Border Protection says.
According to the agency, the drugs were discovered after a detector dog alerted officers to the undercarriage of the vehicle around 4:30 a.m. Monday.
Following the alert, officers guided the driver, a 52-year-old woman who is a citizen of Mexico and lawful U.S. resident, to a secure location for inspection.
That’s when, according to CBP, officers found the drugs hidden inside the gas tank and spare tire.
The driver was turned over to agents with Homeland Security Investigations while a 71-year-old female passenger was released.
The narcotics are estimated to have a value of $175,000.
