Adam Walsh murder solved

I don't believe this is a result of some final peice of the puzzle if it was they would be telling us how they finally solved it. What they are probably doing is hoping that if they give credit to ottis toole then if there is a real killer out there alive he may want to get credity himself and spill some beans. The reason I suspect this is because of the language used by Walsh, he acts as if it is such a relieve to finally know conclusively, now they can rest assured knowing what they have always suspected? They dont say what it was that clinched it for them. ITs a crock!
