The M-cave mystery: What happened to Kenny Veach

>Kenny Veach a 47 year old desert hiker with 20 years of experience. His youtube account went by the name snakebitmgee

>Kenny comments on one of Dr. Steven Greer's videos about Area 51 on how he found M-shaped cave and details his experience. (Currently that comment is no longer up and seems to have been deleted by the channel owner.)

>His comment gains a lot of traction with people urging him to go to that cave again and film it.

>On his second attempt he films himself trying to find that cave again but fails to find the cave again.

>On his third attempt in November 10 2014 he goes on a over-night hike and this is the last time we hear about him.

>A missing person's report is filed for Kenny Veach.

Kenny's Girlfriend comments on this situation and says that the rescue team were only able to find Kenny's cellphone near a mine, his body wasn't found.

9 years later and Kenny's body still isn't found

So what are your theories on this? Do you think he saw things he wasn't supposed to see and got discarded or do you think he died from a accident while hiking, or maybe got mauled by a wild animal? Or maybe entered a cave where he got fatally injured ?

His last video for reference:
