Revisiting Mekayla's case today, and I thought I would share my thoughts.
I was reading an article on CJME.
And Mekayala's mom had indicated she tried texting Mekayla after they couldn't locate her after school.
"She tried texting her daughter, but soon Paula found herself at the RCMP detachment reporting her daughter missing."

Mekayla, is commonly shown in news articles holding her cellphone, on surveillance video, on the day she vanished.
I began looking in to the cell towers in the Yorkton area, and this is what I found so far.
There is a cluster of several towers in the city of Yorkton of course, then there is a perimeter of towers, surrounding the town, on average within 25 km or so, as would be common in rural Saskatchewan.
This is an image of tower locations.
I created a map with 15km radius circles around these locations.
As the RCMP have never indicated that there was a specific area of the search, I am thinking that her cell phone must have been turned off, sometime in the afternoon, when she disappeared. If it would have been on, it would have registered on one of these towers on the perimeter of Yorkton, and as such there would have been a specific direction of travel.
This information would have been recovered from tower dumps from Sasktele, which would have undoubtedly been requisitioned.
It may be a possible then that Mekayla or someone she was traveling with, was aware of tower dumps, and her phone most likely was turned off, prior to traveling outside the Yorkton area, specifically to conceal this geo-location.
Also something to consider would be that someone from outside the area coming in and leaving around 1:45 on the day of Mekayla's disappearance, would have to register in this perimeter of towers, and in the towers located inside the city limits.
