Although the security camera footage is poor, you can see what looks like a bipedal creature stomping its way through the yard. It appears to be walking quite fast and has a large gait. I can't tell the size of the creature from the video, but I would imagine it to be 6-7 feet tall. Further investigation will be needed in the same spot with the same camera to get an idea of the size of the creature compared to a human.
I have included the videos below for your review. I have watched the video a number of times trying to see if I can pick out one or two items that may give this away as a hoax. The video itself reminds me of the old claymation videos from when I was a youngster, the creature seemed to have that type movement to it, but that is common with non HD security cameras. Now, the footprint video, the gait at which the footprints are is very similar to other tracks that have been found of Bigfoot. They are similar to what the first video showed of the stride of the creature. I am going to go out Mythbuster style and say that these videos are Plausible. It could be footage of a Bigfoot. I say plausible, only becuase there has been no other investigations done, just the videos posted on YouTube.
I am interested in hearing what you have to say about the videos. Do you think it could be Bigfoot or is it another elaborate hoax?
