This is awkward. A woman who lives in Mexico and works in San Diego called the cops on herself when she apparently unknowingly transported 30 pounds of marijuana across the border.

According to a report by NBC New York, the unnamed 33-year-old drove her car to work Friday morning, arrived early and was sitting in her car in a parking lot around 4 a.m. when two unidentified men approached her car and began removing packages from underneath it.

The driver surprised the men, who got in their car and drove off. She called the police, who discovered 30 pounds of pot divided into six packages attached by heavy-duty magnets to the undercarriage of the vehicle.

Who put the drugs there—the woman said it wasn’t her—remains a mystery. Police tell NBC New York that no arrests have been made.

Officials want to remind people who regularly cross the border to check their car—as some people become targets by drug cartels as unwitting mules in the narcotics business.

Regular border travelers may be a boon to drug smugglers.

Last year, CNN reported a similar story of a

regular commuter from his home in Ciudad Juarez, Mexico, to the University of Texas at El Paso.

Even though the man, who goes under a fake name to protect his identity, said he was targeted and ferried drugs without his knowledge, he was sentenced to six months in prison.
