Hi All,
Like Tom, I'm extremely hesitant to conjecture on "criminal activities" when (a) there's so very little evidence in the public domain and (b) I also try to imagine what a parent might feel reading unfounded suspicions and accusations on the internet. No one should have to bury a child, and, barring a miracle, there are two profoundly hurt families out there who'll never get over this. My heart goes out to them.
My (non-criminal) thoughts on the 4pm ping:
A few years ago, whilst pondering the Ewasko case, I spent a few too many hours playing with the Serin Tower splash map (
http://www.heywhatsthat.com/) adjusting the Tower elevation up and down a few feet at a time to try and simulate reflections, tenuous connectivity and whatnot. I looked *everywhere* inside and outside of the Park that was along the Ewasko ping arc (actually ping circle).
Specifically for this area in question, I came to the conclusion that (as you exit the Park via the northwest entrance) the entire northern end of the Park Road and the terrain to the east and west is *deeply* in Serin Tower coverage shadow (ignoring a few isolated peaks) except, ironically, the stretch that *starts* at the Maze Loop parking and descends down down down to the Park entrance. That very spot. And indeed, it's at that very corner (I call it "Gravel Pit Corner"; have a look at the topo and you'll see why) where visitor's cellphones that've been out of service for the full day suddenly light up and beep beep beep with text messages, voice messages, etc - confirmed by Adam during an old email exchange, I seem to remember). For a while I became quite excited that I was onto something as that very corner happens to be bang on the Ewasko ping 10 mile arc, similarly to Smithwater Canyon. That observation led me nowhere, but ok...
So coming late to this thread just yesterday, and avidly reading some 20 pages, the significance of Gravel Pit Corner was always in the back of my mind; that corner and a few spots at the north end of the Maze Loop are the only pingable areas anywhere (again, ignoring a few prominences - all of which look like a nasty ascent through jumbled rock piles). So yes, a 4pm ping in that area as the lost couple wandered in circles seemed perfectly consistent.
And then the bomb dropped: the 4pm ping originated around Smithwater Canyon; and I'm assuming that's true, and not some weird newspaper misunderstanding that's totally confused everything and everyone.
I have to echo Tom (pun intended) that a ping from older "flip phones" can only be ranged (or triangulated if there are two towers) by the tower, especially with an omnidirectional tower such as Serin; the tower can't figure out "where", but only "how far". But a ping from a smartphone is a few levels more sophisticated as not only can the tower range the ping, but the GPS chip in the smartphone tells the tower exactly where it is. Can a hobby survivalist disable the chip? Yes, for data services (the famous "disable location services") but (as far as I'm aware) not for cellphone (voice) services. So I'm strongly assuming the 4pm ping gave the tower the X that marks the spot: Smithwater Canyon.
Wow.
A 4pm ping from SWC is not only inconsistent with a Maze Loop hike starting at around 7am, but it's downright contradictory. No one would do the Maze and then decide to walk across the Park Road and head towards SWC mid afternoon, so that story line has no credibility. Then the alternative narrarive that has them totally lost and turned around in the Maze, and somehow wandering across 30 feet of Park Road tarmac and finding themselves in SWC is likewise silly. Didn't happen.
So here's a thought: they didn't spend the day doing the Maze Loop, they were elsewhere. They started bright and early *specifically* to spend the full day doing Smithwater Canyon, completing it late afternoon (leaving the 4pm ping as a calling card). Assuming a Quail Springs location for their car (did the Rangers check the contents of the various Park message boards?) they could be wrapped up by around 5:30pm. They then relocated themselves to the Maze Loop as a comparatively "easy win" to finish off the day, watch the sunset, take a few blue hour photos, and then they planned a quick return to the car knowing they're a mere few minutes from the Park exit and an easy drive back to their Airbnb.
And then it all went very wrong in the Maze.
Just because the car was found at the Maze Loop parking doesn't mean that was how they spent the day. Nor is the 4pm SWC ping a smoking gun for "criminal activity". Innocent until proven guilty, folks.
