 Clark says a social media video purportedly showing the campsites where the fire started has been verified to be of Darling 3, but investigators don't know yet if that camper is responsible. We do know that the fire is human-caused, but even if we know the camp, we still don't know the statistical reason for this fire. It could be any number of reasons. It could be somebody driving by. It could be a campfire. There's any number of reasons there, and that's what our investigators are taking a look at.
