When Chasity Foster lost a necklace containing her daughter's ashes, it was like losing her child all over again. Shaylin Foster, 17, was killed in a car accident in January. In spite of the tragedy, Chasity decided to run the Disney Princess Half Marathon in her daughter's honor, donning the necklace. But at some point, she realized it was missing. Chasity is asking anyone who may have found the necklace to contact Disney World's Lost and Found, or to send her a message.
