Ok, taking away everything single last thing SC has said... which is hard because it's imbedded in my brain. I'm gonna throw out a scenario. Please feel free to correct anything that doesn't make sense. My head is spinning and I'm going with my thought right now.
Charli had no gas in her car and I don't think her intent was to go anywhere with Steven. I need help from locals on this. I think I finally have a vision of the area. I was surprised when I mapped KS West Kuiaha home to SC grandfather home on Kalipo Place and how close they were to each other. Really close actually, right? I feel maybe she agreed to meet him near his house to talk, maybe at a park or just simply in her car. But then again, she was tired, pregnant and it wasn't really the "right" time on a Sunday night after a party to have a long sit down talk about the baby. We don't know what their texts said. Don't beat me up over this because it changes nothing, but maybe she went to get drugs from him for a friend. She could swing by quick, get whatever and head home. Not much gas needed. No long night, no drive down Hana, no reason to tell her family. Or maybe he asked her to swing by to borrow the Twilight DVD. Maybe, maybe maybe. But now I don't believe he ever told her his car was stuck. He made that up from memory from the past with Taylor as we heard today.
If she left West Kaiaha Rd and he walked through the back of his property through the woods and had her pick him up back there or met him there, she wouldn't need that much gas.
He could have have killed her there, hid her truck in the woods/jungle and then drove up Hana in the borrowed truck. How did he get her down Hana then? As we've said driving would be very very risky.
Or she could have gotten in the borrowed truck with him and they both went down Hana. Her car parked on some back road after meeting him around his house. 1000 scenarios on what he would have told her to get her to go. He convinces her to go down the path, again 1000 scenarios on how, and killed her there. I feel like it kinda makes sense that he could have told her he wanted to be with her again and said it was a date to hang out, maybe hook up and told her he found a romantic spot so bring a blanket and a movie, the Twilight DVD, because they were going to watch the movie. He kills her on the path. (Phone ping) And disposes of her right then and there, : ( but it's dark and he unknowingly leaves items behind. That really makes sense in my head...right this second.
In this scenario, her car is back by his house and still, with very little gas needed, he later drives it to the coincidently super close Jaws and burns it.
Sigh. My heart goes out to her family and friends. This is a nightmare.
