I have to wonder how much info could have been gleaned from the cellular data. If I remember right, the cellular coverage was sketchy in the area. This is, I believe, the reason MBM used the texting app - it gave her more reliable texting using WiFi. I assume their WiFi was stronger than their cell coverage. This is sometimes the case for me, I live rurally, and there are cell phone dead areas on my property.
As for the camera data, it would be interesting to also know the reliability of the cameras sourced by LE. On my property, I have motion activated solar cameras, with so-so reliability. I also have a motion activated wifi camera which is about 75% accurate. Sometimes it can just miss movement, not sure why.
I would love to be a fly on the wall. And observe the investigative process, piecing together the data from various cameras in the area, and the timelines. I am so hopeful this case is solved, and the elements of the case we have discussed will be made clear.
IMO
