The thing is, we have the RCMP saying there was no vehicle, which basically rules out a stranger abduction. We have family passing multiple lie detector tests. Which yes, are not always correct but usually are. And then, of course, a massive search turned up no sign of them. So where does that leave us?
Good points.
Under this scenario, which is helpful to frame anew what might have happened to Lilly and Jack, looking back, sadly, 7 months+ now since they disappeared, regarding one possible answer to the question" "So where does this leave us?"
IMO, overarchingly, if all the above presumptions are true, it still could make sense, looking at what would be:
"Someone Who Was Not":
-- A stranger to Lilly and Jack
(e.g., someone who knew of them, but they didn't know -- IIRC, one of their neighbors said they didn't know any kids lived on the Martell property?)
-- A random person coming upon them by happenstance that morning
(e.g., someone who would grab them from playing in their front yard after they were known to their school to be "out sick with a cough" and see 2 unattended children with no adults around -- IIRC, there was an MSM article about 6 weeks ago which said only Lilly had a cough and Jack was kept home as well to be on the safe side).
-- A family member who "passed" (paraphrasing of course) polygraphs during which they were asked about them disappearing and the possible circumstances under which they disappeared
(e.g., DM & MBM, and IIRC, DM's mother was also subject to a polygraph [as were 50 plus some people, IIRC or at least that many people were interviewed by LE with polygraphs available to be used with consent if needed).
Although DM's mother who lived on the property's physiology wasn't suitable for LE to interpret her results and/or something along those lines.
Also, IIRC, DM's brother, who at first was said to have also lived on the property, but that was later discounted, was shown in a photo with DM sitting behind him on DM's recreational/all terrain type vehicle/all wheel drive with a long bed seat which could hold several people, that looked like it was a snapshot or still from a video of the brothers having just come back from driving around looking for Lilly and Jack that morning.
IiRC, he (DM's brother) was behind DM in the driver's seat leaning back and looking away in that shot of them together on DM's recreational vehicle.
So... it must have been "someone (else), somewhere, who must know something" about Lilly and Jack vanishing that fateful morning.
Unless they "wandered off into the woods" and haven't been able to be found.
Also, long windedly catching up here...
IIRC, DM said he thought (after the fact) he heard a scream/screams, while LE was searching, initially, which he said was drowned out by helicopter noise from SAR teams.
Perhaps DM thinking he heard a scream(s) could have been wildlife doing what they do or reacting to the loud unusual presence out there in the remote territory of LE SAR teams descending in full force.
Or it could have been Lilly and/or Jack screaming because they had wandered too far and/or met up with someone who they initially thought was a good person with a good scheme for them to "go on an adventure while mom & dad & baby sister were sleeping in on a day off from school" they were willing to meet up with at first, who turned out to be somehow scary/ not what they seemed, when push came to shove...
