Why this dog may be key to discovering what happened to missing Idaho kids

An Arizona dog trainer says he may have been one of the last people to see 7-year-old JJ Vallow before he and his sister Tylee Ryan, 17, went missing last September. Neal Mestas, of Gilbert, told Inside Edition that he trained a service dog, a Goldendoodle puppy named Bailey, for JJ, who has autism. He says he knew the family when they lived in Arizona and was "puzzled" when the dog was returned to him prior to their move to Idaho.
