Apple Health records from the phone and watch
Whiffin identified the last heart-rate measurement as 5:23:52 PM and the last phone flight-climb recording as 5:38 PM. He distinguished the end of recorded health activity from other possible phone activity and explained that a person could continue moving without carrying the phone or wearing the watch.
About
Whiffin's testimony limited any inference that the end of recorded health activity established the end of physical movement.
