I do wonder myself though about the phones. They were obviously USING the phones because going to Kiely's car and charging phones was something SS talked about. iPhones charge quickly, right?
My understanding as a parent is young people prefer different types of social media. I'm sure the invites are out there, but TOS would prohibit sharing. I think photos, videos, etc are probably on phones and maybe were shared on places where we would not easily come cross them. i.e. you wouldn't type in "Beekarina, Websleuths Party '22" and find a big album.
