Thanks for the article.
Two thoughts for me--- for one, I was sure I saw Kaylee at the register paying for the food and that is audible in the stream
Second, I get that someone completely deranged by lust, rage, frustration or revenge could easily lose sight of any logical thinking. Still, as it appears widely known that the truck is live-streaming, I think it would be exponentially more difficult for the killer if he was among that crowd near Maddie and Kaylee. He would know all his actions and interactions are being recorded.
That wouldn't matter, perhaps, to someone on a mission to murder the girls, but IMO it doesn't align with the seemingly meticulous way he got in and out of the house undetected. That speaks to me of planning and trying to avoid leaving clues. Therefore I find it harder to believe it was anyone at the truck at that time.
Jmo.
P.S. I'm not a fan of every single thing in life being broadcast, but that's the world today. People live stream their cats, giraffes giving birth, just everything they can do and apparently there's an audience for it all. Yes, it makes it easier for a stalker, but real time social media already does that.
