The Laverty part of the PG film story is among the most interesting of all. He was the only government official involved, he had prior experience with a nest and footprints, his, private photos got into the public sphere almost immediately, yet he has remained very quiet about his side of the event.
Laverty had heard of the filming while off for the weekend in Eureka, and on their way back to work, he went to the site and took the photos. It is clear that he was a "bleever", and he was wise to remain quiet about his opinions. His career turned out very successfully.
AFAIC, "no evidence" strongly indicates no dead sasquatches. I have no reason on Earth to believe his story at all.
