The Fourth of July is often a time of celebration, but for one Navajo family, the day brings grief and misery. Laverda Sorrell vanished on July 4, 2002, in Fort Defiance, Arizona. The area is located within the Navajo Nation. Almost 20 years later, family and friends haven't seen her since her disappearance.
