I am not sure how many people were there, I myself have personally never been to a GNCC but I keep up with all of them (or I try to at least). This was a video from Matteson Films, keep watching till the end, its an exciting finish, and if anyone has any details on if the people are okay or what exactly happened please fill us in!
