If the text was sent (either written or a previous draft) at 1:20, that would have been while she was in or outside of Tempo. They say the phone went dead right after that message. Wondering how they know it went dead, and if it did go dead at Tempo, wonder why or how. Battery just happened to die?
Didn't know phone went dead. That could explain why LE can't get much more useful info from Hannah's phone. But they do have JM's phone. Unless he turned it off that night when he was with Hannah or it went out of batteries, that should come up with some idea as to what his travels were.
