A woman may have unknowingly smuggled 30 pounds of marijuana from her hometown in Mexico to her workplace in San Diego, California.

According to San Diego narcotics detectives who spoke to NBC, this 22 year-old unidentified woman crossed the border driving her own car on Friday around 3 a.m.

She had arrived at work early, and was sitting inside her care when two unknown men walked up to her vehicle about an hour later. They started attempting to take items out from the undercarriage of the car.

She then startled them by making her presence known-the men dashed into their black sedan and drove away.

The woman called authorities, who found six packages consisting of 30 pounds of marijuana, attached to the car by eight crescent-shaped, powerful magnets.

She maintains she did not smuggle the marijuana across the border. Officials say they still do not know who put the drugs there.

No arrests have been made.

Last year, CNN reported on a similar story on "Blind Mules": folks who unwittingly carry drugs into the US from Mexico.

A man whose name was changed for safety, Juan Andres, drove across the border for work at the University of Texas at El Paso from his home in Ciudad Juarez, was singled out for a vehicle inspection by Customs and Border Protection, who found two bags of marijuana in his vehicle's trunk. He had no idea how they had shown up there, he said, but was arrested and detained for an extended period of time.

It seems drug lords will get as crafty as possible to find ways to transport their goods. Earlier this year in the Mexicali area of California, the Associated Press reported on a cannon that traffickers used to throw packets filled with marijuana across a border's chain link fence and into California.
