The dad reporting that she has been in contact does not necessarily specify the manner of contact. Furthermore, her friend says she sent her an SOS message recently on Snapchat, and provided a screen capture of that message. If CA's contact with her family was via text only, there is no way of knowing whether it is actually her corresponding or if it is the individual she is purportedly with. Looking at her IG, she seemed pretty active until recently, so one would think if she was in a "happy" place and in the company of someone she wanted to be with, that she would likely post about it for the world to see.
TLDR -
Makes no sense why she vanished for so long with no contact, which is why I am skeptical of this particular report of contact.
