You are veiwing this as Matt's PI and attorneys against the LE. I have seen no indication that the relationship is like that. This isn't a game where one side wins and the other side looses. In this, if either team looses, it means something terrible. It makes perfect sense that they would work together to find out what did happen. And yes, I do think that if they found anything about Gails whereabouts on the computers, they will or have informed the LE.
Matt has hired THE expert PI in the area to search for Gail. Once Gail's PI turned his info over to LE, if he had anything that could assist in that search, I can't see any reason that he wouldn't share that with Mike Mathis.
confused,
Do you know which LEA's have been fully informed by both Gail and Matt's PI's? TIA.
