I think it's a CHP officer. They can easily access helicopters, boats, fast cars, and motorcycles to get where they're going quickly all across California, Nevada, and Mexico. Same places red john has killed. I believe the HQ is in Sacramento which is where most of the rjk have happened. Plus Jane shook hands with chp officer O'Donnell and couldn't hypnotize him. For one episode it was all about their interaction. He may be a red herring but I definitely believe it's someone from the California highway patrol who's in with visualize and friends with a lot of cops/FBI in visualize as well. It may even be Bret stiles' son.
P.S. the one who killed Rebecca had a chp uniform on and was in the same holding area O'Donnell was in if I remember correctly.
