I can see that it premeditated and marginally planned. But do you think it was well planned and well executed ? Because THAT, I just don't see.
You can't?
To enter the Closs home at night, kill the father, find and kill the mother, find and force Jayme into his/their vehicle and get away unseen by anyone within 8 minutes of the 911 call and the cops arrival suggests that it WAS very well planned and perfectly executed.
That's why I think that if it was a lone white guy sex pervert killer he had military training. Possibly the same may be true if the perps are tied to the local foreign community. In the latter case I believe there were two perp's working as a team. Otherwise just one perp. Just my hunch. In both cases Jayme was the target. If my second scenario is correct there is a good chance she's still alive. In my first scenario, not so much.
