From bigfoot researcher Blayne Tyler:
Most know that on Oct 20, 1967 the most important wildlife footage ever filmed was obtained at Bluff Creek CA. 49 years ago this week. However most are not aware that there is at least four other reels of 25mm film from that month long expedition. Important footage taken by Roger Patterson that went missing soon after. Specifically the 2nd reel* which contains the documentation of the encounter immediately after with Roger and Bob. Which also has the examination and casting of (Patty's) track way of prints in real time. Knowing the value of such footage, it seems unlikely that the missing reels were " forgotten or accidentally misplaced" It's also very possible that Roger may of unknowingly recorded other supporting evidence such as stick structures, scat, hair, audio or even other Sasquatch. Green, Dahinden and Gimlin had suspicions of who might have them but nothing has surfaced to date. The missing reels of 25mm footage have a historic significant to say the least and need to be located, reviewed and made public, Where are the missing reels?
