He may not have had a real gun either. If he did, he didn't want to shoot them, because of all the people at the park, and it would draw attention to them. He took a big risk, because if one of the girls took off, or both, he had a problem. He wasn't smart, he was stupid, he just had some luck on his side, for now.
We don’t know the read motive. If it was purely sexual and thrill, with the element of “I am going to commit this perfect crime”, then, he is very smart.
But it suddenly hit me that the reason for the murders could be more practical. Sexualized, yes, but it is secondary.
I read about the arrest of pedophiles in another state and suddenly thought, why not in Indiana?
Here is the perfect reason for a crime like this. One does not need to trade kids into slavery. It is enough to obtain *advertiser censored* images of young teenagers, even paying them, and then sell this stuff online. The guy can live anywhere, I think, he is semi-local, but he can operate from any house. He probably has to have good Internet access, this is all.
And imagine that one day, a girl, instead of becoming the next victim, or maybe hearing from a victim, suddenly threatens to oust him out. It is a lot of money to lose, it is a huge threat. Loss of business, loss of prestige.
This would be the reason to commit the crime. And because the guy is into such stuff himself, since he sells it, the CS looks ghastly, but exactly in the way to make people cringe.
I doubt he sold those photos on the dark web. The goal was to create distraction, like, serial killer, signatures, etc. IRL, the guy lives for money, and he killed because he thought one of the girls was danger.
So, he is, sort of, local, maybe not Delphi local. He may even be religious. He doesn’t stand out because all his special gifts are good IT skills and strong Internet. And he probably has contacts with some criminals, but minimal ones. He also lives slightly above the means, but to those who are curious, he explains it by trading in cryptocurrency. (He probably does it, too.)
This is my portrait of the perpetrator for today. Smart? Yes, but rather, organized, not impulsive. In this, he belongs to the minority, as he can postpone instant gratification.
Also, he is probably well-read and quietly despises his bosses as he thinks he is way more knowledgeable and sophisticated, but he doesn’t show it.
