Interesting episode from "Unconcluded". They interview Jennifer's dad, Drew.

Audio in this episode is poor especially when he talks about Jennifer's phones. But the message is that he really doesn't have any meaningful information on the activity of the two phones she had and he tries to tell everyone to quit focusing on the phones.
This is really strange because in most cases the missing person has ONE cell phone and it is either found at home or in their car or not found at all. Here Jennifer has TWO cell phones. What are the chances the abductor finds the 2nd one? Or finds the phone Jennifer is going mail, assumes it is hers and looks no further? But here there are TWO phones and no useful data.
