In addition to the trajectory of movement...the defense pointed out the speed of the movement. I think both would need to be considered in an analysis. I know when I am looking at the Find My Phone/Friend on my iphone generally if the person is driving and in good cell phone service area the movement is smooth and at a pace consistent with the mph of the vehicle or it shows a static location and approximate if not totally accurate address. If the phone is in a very weak reception areas it will bounce around really fast and finally settle on a location sometimes less accurate. We are probably 15 miles north and 15 south from towers and 25 miles east and 50 miles west of towers with obstructions in all but the west. I have to believe that data retrieved other than directly from the phone in theory should be more accurate but when this rapid movement and speed were brought up at the preliminary I was like OK....I want to understand this better since I had observed it in phone apps. This is largely contributing to my unwillingness to settle on the conclusion that he was racing around at top speed chasing Suzanne. There may have been movement and I would guess yes he came home, and was on the move in or around the house as we all do sometimes around our homes, but it may not have been the movement captured in the data. Data forensics has gotten very interesting but it can also lead to false assumptions in other than expert hands is my guess.
I measured the distances and did the math.
BM is going 5 mph, a medium running speed around and through the house.
