After reading a lot of the posts on here and following the links to articles, my gut feeling is that this man that is doing these murders has connections to the Lake Charles. I would be surprised if he is a truck driver, or one of the drug runners that access I-10 to run their drugs.
He is picking them up in Jennings. He is dumping the bodies at the outskirts of Jennings off a highway that runs to Lake Charles.
Where is he killing them? In that rural area where their bodies are dumped? Does he pick them up, kill them and dump their bodies on his way home to Lake Charles?
I don't think it's a "stranger" though due to the fact that all the victims knew each other or were related.
Sheriff Edward's has said they don't think the victims were killed where their bodies were found.......he thinks they were killed elsewhere and then the bodies transported to where they were eventually found.
