Hey, Chip - you're talking about someone's developmentally disabled child who has been easily taken advantage of before because of an overly-trusting nature on her behalf, not her parents. We're not talking about a 'dopey skier' who decides to go off the trails.
And as far as any 'expenses incurred', most of the work was done by friends and family, and a few wonderful people on this Forum who stepped up to help. The El Dorado County Sheriffs Department and the FBI did not get involved until very late in the search...and guess what? They found her.
