Doesn't mean she was alive, does it? All the timeline says is that "Sixteen minutes later, at 2:28 a.m., Guthrie’s pacemaker app showed it had disconnected from her phone." Wouldn't this indicate that she was taken away from her phone at that time? Could she have already been deceased at that point, but still have her phone on her?
I don't know how pacemakers work, if someone else could chime in here. Would the app show activity if she was deceased and was still wearing the watch?
