I noticed that local pattern too.
Cassie's last contact was a text, yet her phone is missing. Who sent the text? I will conclude that the phone is probably still with her.

For sure, BR is of great concern.
I did scan random pages of the topix site, and saw three things that I had not heard before that raised my brow. They are probably made up, because like I said - that place is a hot mess. But, I would still want to know if there is any truth to it: 1) That night, was Cassie's phone pinged to a house on River Road? 2) Was BR phone then pinged in Casscoe? 3) Does LE/FBI have a lot more to go on than we realize and they are just putting it all together?
