Okay; I did my homework better this time, I hope. I read the transcript of the entire interview linked in incognitus' post and two statements seem suspicious to me.
1) Cassie Laundrie: I've cooperated in every way that I can. I wish I had information or I would give more. I, I, I...this is all I have is - I gave to the police.
Question: Have you talked to Gabby's family?
Cassie Laundrie: No one's reached out to me and I don't know if it's appropriate for me to reach out to them when everything with everything going on.
Question: What would you say to her family just so they know that you're..."
(Remember this was aired at 0730 on 17th of September ~ Long after the Petito family says they tried to contact her.)
2) Question: And when you just heard the news just in general, like that she's missing and that your brother's back here?
Cassie Laundrie: I don't understand. As much as everybody else I'm learning everything from the news, too.
Remember, CL is claiming this even though she'd already met with her brother twice since his return. It seems very unlikely to me that this tragedy would be off limits for discussion! My family must be weird then ~ because this would never fly!!! I find it more plausible that the campground meet up may have been specifically to discuss everything and make a plan. Especially since it's been mentioned that they may have been worried about their phones and home being bugged.
My 2 cents of moo.
