He may have disappeared due to a 4D overlap. Just speculating...
In most of such cases, I think, the previously correct 3D geographical area changes into - suddenly EXTENDS - into a geographically anomalous 3D-4D-Bi-Density "Twilight Zone". Bigfoot, I think, instinctively opens such "dimensional holes" to lure its victims into: routinely how ranchers drive cattle into an intended direction on the fields.
So the "now properly missing 411 person" suddenly sees a (for example) open grassy field appearing in their field of vision - out of nowhere -, but they are
now in bi-density 3D-4D with EXTENDED 3D-4D GEOGRAPHY =
new safe walkable areas (not in our 3D world) appear out of nothing right before their eyes. (See book reference at bottom of this post.)
But normally in our 3D - to the eyes of the rescuers - that area is as IS, e.g. its a dangerous rocky terrain with chasms, unwalkable / unapproachable / unclimbable places etc..
So:
1. Rescue continues in normal 3rdD Earth with our Linear Time Clock Ticking = rescuers keep seeing only 3D-Earth
2. Victim now does NOT see normal 3D-Earth anymore, but is ENGULFED with new sky and new horizon and all in a completely new world and continues to move in this (extended) 3D-4D Bi-Density Zone with his-her Personal Time Clock ticking - for the victim a lot more time passes as he-she is lost, understandably. Victim(s) probably in a state of some confusion and curiosity - begin to
walk further into such extended bi-density areas and make distance and encounter fatal accident event / get attacked by wild-life there and or abducted and killed.
3.
Meanwhile on our 3D normal Earth - that exact same ENTRANCE into the bi-density window closes - denying entry for rescuers / searchers accurately measuring 3rd Density Linear Time - to them CORRECTLY the "now properly missing 411 people"
are swallowed up by the "hidden dimension".
But for the Missing-411 victims - for whom their personal time clock keeps running (with their watches stopped right at entry into Twilight Zone?) - they are now walking in the
alien density / mystery dimension and get abducted, trampled by beasts there / or encounter dangerous terrain-type life threatening situation there and die there collapsing on the floor or falling into a chasm or suffocating in deep water, still in Twilight Zone..
Abducters - if any - may know about this and they probably just dump the victims body right there: still in Twilight Zone.
COMING BACK:
Then that geographically anomalous area cycles back, - spits back anything that doesn't fit its "Twilight Zone FRV". Same, I think, how natural geyser-area pressure changes happen to make geysers erupt - so the entire geomagnetically anomalous area starts switching back and forth like a geyser / bubbling swamp and pulses between
1. bi-density 3D-4D area mode, then the area
2. switches back into our normal 3rd Density again, and the body of the missing-411 victim - now dead - appears
spit out by the anomalous geographical area. Just like how seas wash up bodies in 3D. But these anomalous areas are probably like swamps or seas they "regurgitate bodies" via their (possible) bi-density tide
ebb and flow natural process.
END RESULT:
3. Linear Time measure for rescue authorities: 4 days 12 hours (example)
4. Linear Time measured for 411-victim: 10 days 18 hours. This is how long in "personal time" the victim was lost because having been swallowed up by the Twilight Zone / bi-density / alien dimension.
5. Authorities don't have a clue, since they searched the exact 3rd Density Earth area during their 3D Clock Time: 4 days 12 hours
6. Coroner or
medical examiner might notice that the victim's body IS AGED / DECOMPOSED FURTHER rather in a condition for a person missing for 10 days instead of the 4 days elapsed since then and does not understand or
know, but do NOT want to get fired for pressing the matter. Instead everything is efficiently swept under the rug and everybody keeps mum to keep normal appearances and their jobs.
7. Therefore we have these tight lipped authorities publishing minimal info. Because they don't know and they don't understand
High Strangeness and it makes their brain hurt anyway, so they drop the case.

The Mists of Time: Common Origin?
Former Western Michigan University professor of natural science Michael Swords recounted the incident, which was originally sent by a copper miner to the late UFO researcher Allen Hynek, on Swords’s blog, The Biggest Study.70
The location was in northern Canada near Yellowknife, on Coppermine Mountain. (Swords provides a map.) The miner encountered the mist while exploring the bottom of a fifty-foot-deep gully full of what looked like very old rocks and little else except for a tubular mist that was distinct from the rest of the atmosphere. Rather recklessly, he decided to walk into it and was amazed to find himself wading into a field of three-foot-high grass. He was able to step out of the mist and then back in without problem, until he walked in a bit farther and saw a lakeside oasis—with a lake set diagonally into a hillside—and two robed, humanoid figures watching him as they floated several feet above the grass. At this point he decided to exit, which he could manage only with great difficulty.
Swords asked, “Did our fine fellow not only walk through a portal mist into Faerie but even encounter two of its inhabitants?”71 He also mentioned several similar encounters described elsewhere on his blog. The floating humanoids bring Christian Page’s Canada incident to mind, as it seemed that at least one of the entities that carried him into the cornfield was either floating or much taller than the others. Were they perhaps carting him off to the nearest portal into that same, strange world?
Some years ago:
1. While doing Eiriu Eolas in my room - for some reason - I kept the audio player running so I was hearing Laura's steady voice.
2. I also started walking slowly in circles and
with accurate, measured steps to the rhythm of her voice around the bed.
3. Breathing properly and walking slowly in such a way put me into a trance state.
4. I started noticing - feeling
Extra-dimensional Bi-Density Pockets suddenly appearing in my room around the bed. They were the size and form of a man-shaped Egg. (Castaneda's Luminous Egg)
5. These extra-dimensional invisible pockets seemed accessible to my - now in trance - state.
6. They were extending normal apartment space in my room by several square feet! They were accessible. I felt clearly that if I stepped into one, I would be no longer in my normal 3D-apartment room.
7. The Pipe Breath.WAV sound file lasts for 17 minutes 49 seconds. When it ended, my "walking around in trance state" ended and I switched back to normal 3rd Density "everyday-mind state" and these extra-dimensional pockets disappeared to my now normalized senses.
The Portal:
Occasionally during a year - in semi sleep state lying on my bed - in the pitch black darkness of my room - I switch into Night Vision / "Cat Vision" mode - "in a couple seconds" start seeing my room in faint silver-grey color Night Vision overlay - and in the focus of my tunnel-vision with some "TV no-signal noise-effect" I see appearing, opening in the air a portal "HOLE OPENING IN 3D SPACE".
Appears and coalesces into solid portal hole form - size less than two feet in diameter - , hovering there at the height of two feet in the air and just like Gorman on the Skinwalker Ranch through a similar portal seeing a completely different skies - I see through that portal - with unchanged distances - my room in an alternate-parallell timeline / dimension. I can make out different furniture and I sense - feel/KNOW - that someone is living there! Lasts long enough for me to look around. I can look around "into the alien-space", because this portal hovering follows my eyes in the focus area of my tunnel-vision.
The portal closes when I get embarrassed / afraid enough for peeking into someone else's life in that "alternate dimension" / timeline: mentally "shaking my head" I "re-arrange my brain-state back to normal" - the equivalent of any of you shaking your heads, to clear your vision when you come up from underwater.. and then - as intended - my mind loses focus on it and the portal closes, as all portals do when they lose energy in any window faller phenomenon. This is a solid, repeatable / repeating phenomenon with constant parameters: Conditions remain reliable and thus are familiar.
