If he was attacked by an animal there would be sure signs of it. Clothing scatter, human remains, etc.

When you vanish without a trace it takes away from all possibilities of an animal attack.

Especially if there was such a thorough search completed. They would have found evidence of an animal attack.

I think we have to rule out animal attack at this point...

Is there any bodies of water in that area. If so, has any scuba searching been done ??
