I believe that that can happen, but then it should be important to know if there are any elevation changes on the route KR and JO took that night! They only went a few miles from the bar to 34 F, so easy to check. Is this part of the state all up and down in elevation like that? Seems doubtful, but I'm nowhere near MA, so who knows.This was interesting testimony from the trial. I'm inclined to believe that out of all the data in this case that possibly could be wrong, this is the data that I most believe could be inaccurate. Maybe because I know that my fitness app sometimes says I am swimming when I am actually folding laundry.
I was recently watching a different live trial (the Susana Morales case) where a teen was kidnapped by an off-duty cop. She was taken in his car, and then at some point killed and placed in the woods off the side of a rural highway. Investigators used data from Fitness apps on both the victim and perpetrators phones to show activity levels, when they occurred and what they showed. The prosecutor at one point asked about the data point "stairs climbed" that occurred after the kidnapping took place but when it was presumed the victim and perpetrator still would have been in his car and the lead detective said that this is commonly seen with "elevation changes," it often has nothing to do with stairs actually being climbed. My head swiveled around when I heard that come up in this other case. This was said very matter of factly, almost dismissively and not challenged on a technical basis as far as I know (I haven't watching the entire trial yet).
