maybe something in the crime scene shows preparation, organization and preparedness for two victims.
which leads them to believe this was not a random encounter and that this perp somehow targeted and located his victims through the internet.
as I said, I see him exiting his vehicle quickly with his items in his coat moving quickly towards his target.maybe he has stuffed everything in his coat etc so his hands are free. Perhaps he starts with a napsack or pack of some kind , but puts it all inside his jacket so he can quickly pull his gun.
the crime scene tells some things about the killer...for instance he brought zip ties for 2 people, he had different knives , plastic bags, instruments, *advertiser censored*, maybe a bludgeon or tape.
so when he came to the park there was a plan already in motion.
and yes, if this guy is a dark-net stalker and has harnessed the internet for stalking purposes, I definitely think he will read here.
kind of reminds me of the zodiac killer. who also comes running into a nature setting in a costume to hide his identity and murders 2 victims...would our killer send messages? try to communicate with LE? send a sign?
he's gonna do this again if he can, and if he isn't locked up right now, he definitely can.
MOO
