Police in Washington State cannot find a missing 2 year-old boy and they're suspecting foul play's involved after he vanished from his mother's car over the weekend.

FOX News Radio's Jessica Rosenthal reports:

The mother of two year-old Sky Metalwala told Bellevue Police her car ran out of gas Sunday. Julia Biryukova says she walked with her four year-old daughter to a gas station and left Sky in the car.  When she returned an hour later, he was gone.  The Father, Solomon, took a polygraph; its results were inconclusive, but officer Carla Lafrate says it's a different story with the mother.

Lafrate: "We continue to invite her to take a polygraph, and as of yet she has not taken one."

It turns out the parents are going through a messy divorce and Biryukova recently alleged that Solomon was abusive and she would not agree to a custody deal.
