"Sexually Motivated" yes it appears his intention was to hit on her. I don't know if his intention was so sexually assault her nor do I see any evidence at this point he did.
Yea I don't agree there was any intent to commit a crime until he was rejected. I also don't agree with a couple posts here saying a jury would convict him with sexual assault without evidence. I mean look the guy is terrible for what he did, but the reason we have the legal system is so people get charged for the correct crimes and not charged based on peoples assumptions. In order for that to happen he evidence needs to be there. No matter how obvious it is to us and others that he did these terrible acts if you look at just the evidence his lawyer is obviously looking for loop holes, because notice in the confession CR never admits to actually killing her.
CR confession is very carefully stated that he chased her then doesn't remember anything else until he is in the car. He never mentions in the confession he killed her. He "chased" her, then all of a sudden he remembers nothing else until he remembered he put her in the trunk. Then he dragged her body after he conveniently found her in his car. I hope the prosecution gets enough facts where they can just open and shut this and not have it drag on by the defense.
