I asked Whirlingmerc from my Youtube video to keep us informed on Dyer, the body and any documentaries. Here is his response:
Comment on your video: The Next Newspaper Bigfoot Column,
The short film is owned by the BBC and there is a date for showing in Canada in April. It's supposed to show the shooting and rolling the body to the truck.
Then after that there is supposed to be a documentary about the autopsy that is separate... I think. International Documentary festival April 25 though May 5... so... in a month
We will see soon enough, I think likely real, but we shall see.
