Several reasons.
(1)From the very first moment they had their CLOSE PERSONAL FRIEND, Diane Halfman , at their home to advise them on police procedure, questioning techniques, etc. Diane Halfman was also a CLOSE PERSONAL FRIEND of the INVESTIGATORS, and so likely DIRECTED THEIR ACTIVITIES.
(2)On other threads is has been discussed that there is this wierd coincidence of DAMON having been in close proximity to many CHILD DISAPPERANCES, starting with the ADAM WALSH. (Yep, kid of John Walsh, of AMERICA's MOST WANTED). Yes, he was a teenager back then. So what. Child molester/killers don't suddenly hop into being at 50 like they would have you believe DW did.
Then Michael Nigrete, who just happened to be the kid of one of DAMON's CO-WORKERS. There have been several others.
Is it possible Damon was involved. Well, if you want statistics the fact that Damon was VERY NEAR something like 4-5 child kidnappings/deaths and DW was near only 1, well, YES.
That little girl was being abused, period.
UCAN, where did this come from? That is so interesting and would love to look into it more, let me know-thanks!
