Its brett partridge, and from my evidence I recorded the episode and rewinded it multiple times. The guy that was cut up by RJ was way to big and chunky to be partridge. I believe the guy on the ground that cut up was reede smith and because partridge was at the house thats why lizbon said partridge because thats who was on the map at the house. And brett partridge is just weird and his voice is similar to the call jane got. please email me if you disagree or agree.
