Yes, and the PI also indicated that he knew Deorr Sr prior to this and then went on to say things like he wouldn't do something to him, the boy was his life, and so on...so I wonder how much that affects his judgment about the parents in this case.
Also, according to his web page, the PI's own children were kidnapped and missing for 2 years, and he located them, apparently alive, in Mexico. I am not sure if this was a parental abduction or a stranger abduction, but that experience probably also colors his views about the possibility of Deorr Jr. being abducted and still being alive.
He is presently completing a book about his years as a Deputy U. S. Marshal that involved the stopping a hijacking at the Los Angeles International Airport, making many high profile arrests and locating his two kidnapped children that were missing in Mexico for over two years. http://frankvilt.com/about/
