A Crime Watch Daily mystery in Washington state: A little boy is missing in the most unusual of circumstances.

A little boy missing. A mother not talking. A father desperately searching for answers.

This case really has haunted the tight-knit city of Bellevue, Washington. Police say they've spent more than 14,000 hours and more than $2 million trying to find little Sky Metalwala, a 2-year-old boy who vanished after his mom says she left him for more than a hour in the backseat of a car.

What happened to Sky Metalwala on November 6, 2011, is now a mystery that has investigators scratching their heads and has everyone else pointing fingers.

What really happened to little Sky? Crime Watch Daily goes knocking on the door of the one person who holds the key to this mystery: Julia Biryukova.

Julia Biryukova gave birth to a new baby boy in July 2015. The father of that child, Alan Morgan, is a convicted felon.

Both Julia and Alan have filed orders of protection against each other.

Seemingly lost in all that drama is her missing son.
