The more I watch, the more I suspect Lorelei. She seems to be at the center of everything and remember, she is the one who supplied Jane with the list in the first place. How convenient. She has an ongoing vendetta--the murder of her sister, and showed up out of the blue in Las Vegas and inserted herself in Jane's life. Then she shows up in the car with the Red John "dummy" and the poor victim for the shootout in Henderson. This is all too convenient.
