Conclusion after some research on here plus personal opinions.
Bret Stiles is the father of Raymond Haffner.
Robert Kirkland is not working for RJ nor he is RJ, he's hunting RJ cause he's mostlikely the boyfriend of Miranda.
Brett Partridge was the original RJ but Bruno Heller kept going cause show got popular so RJ could be changed now.
So.. RJ could be one of Haffner, Partridge, McAllister imo.
