SALT LAKE CITY — A West Valley City woman who was facing charges that she used a baby as a "drug mule" has jumped bail.

Authorities said Marta Rubalcaba, 42, has been missing since Monday when she was scheduled to appear in court. She was free on $10,000 bond after being arrested and charged with using her 3-month old niece to transport drugs.

Earlier this month, police stopped Rubalcaba and Cynthia Lopez-Garnica in Bountiful. Officials with the Weber-Morgan Narcotics Strike Force said the two women were trying to transport heroin to Ogden by hiding the drugs under the baby’s head in a car seat.

The infant has been returned to her parents in Salt Lake City. Officials said the parents could also face criminal charges as well. The investigation is ongoing.
