Hey all :) .. i suspect 




Brett Partridge
after 1st episode of 6th season ..i can show u my theory through the last scene of episode..

1.at 1st pic u canot see light beam comes from the window and u can see it comes from the other side (rember this point )

2. at 2nd pic u can see the same light beam when she saw the closed door became opened and thats mean she is stand infornt of the window

3.3rd pic  is the my theory :) there is the same light beam from the same angle and she stand in fornt of the window and Red john pulled her  from hry back so thats  mean we have 2 choices :
A.Red john attacked from the outside but we didnot hear any sound from window 
B.Or 




Brett Partridge 
attacked her and it is the logical choice if u see the scene again u will understand what iam talking about .

So, if this scene made perfectly (no mistakes like movies :D ) and if




Brett 's body will not appears in the next episodes .. i can say it is him 100% ..but if we will see his body , it will be a big mistake in this Show .. it is the Logic.

please Comment if there is something wrong ..have a nice day :)
