Definitely a costume.
In fact, I know a local man who is a bit of a camera trap fanatic who had his wife dress up in a gorilla suit.
He has his camera trap set up over a carcass of a road-killed deer.
He has had some very interesting photos, including a fight between his feist dog and a red-tailed hawk.
For a joke, he had his wife dress up in a gorilla suit and stand over the deer carcass. He then took the photos e-mailed them to all of his family and friends, some of whom believed it was authentic.
The camera trap leaves a time stamp, and his wife was photographed in the gorilla suit on two different occasions that were nearly two weeks apart. Because he had photos from two different dates, one of the people who believed it was real warned him to stay out of the woods because “That thing is staying around there!”
BTW, has anyone heard of the famous Ivan Marx footage of a limping bigfoot? Marx also had his wife dress up as a sasquatch and filmed her limping around.
You can see his entire crappy documentary on youtube!
Do I believe in bigfoot? Not really.
