that's interesting dave bursten saying that because didn't doug carter say it was the person on the video is the voice and it is one person only?There is something important stated at 1:37 IMO:
"People want to make the assumption that the voice saying "down the hill" it belongs to the person captured in the image from the cell phone, that's not necessarily the case."
if it wasn't him it was Tobe Leasenby or kim reilly.
But one of them said it.
