I realize I'm putting the board on 'blast' again here, with my opinions and I DO apologize. I don't mean to monopolize the floor.
I do want to add one more point though as to why I feel so strongly about the involvement of the social media angle in this case.
I went back and pulled the following article with the comments made by State Police Sergeant Kim Riley right after their murders.

In this article, he said, and I quote: "Parents should make sure they know where their children are and what their children are doing, and if nothing else, know what's going on in their lives. That's the most important thing I can say at this point in time."
These words were carefully chosen by him. They reflect the knowledge that LE had about the crime at that time. Personally, I can't imagine those particular words being said about a random type of encounter at the park.
The girls were dropped off there by a family member, and were due to be picked up by one as well. They were there to hike and take pictures.
Does that sound like a scenario that LE would feel compelled to warn parents about? To use those specific words of knowing where your children are and what they are doing? Do those words fit?
WE (the public) do not know whether Libby posted her plans on social media for that day. But LE DOES. LE has in their possession every single word, message, text, etc posted or sent by Libby.
Imo, their words reflect THAT type of concern. Their message is telling parents to be aware of what their children are doing ONLINE. On their phones. Not for a hike in the park.
I cannot see that specific choice of words by LE for any other reason.
