for some reason i dont think bob kirkland is actually dead and i think he is  still alive and some how managed to fake his death some how maybe swapping the bullets for blanks i don't know,

and i think the thing about his brother being recruited by red john could actually be a personality disorder (but probably nothing as complicated as that)
 
i am not to sure how but for some reason he seems the best fit out of everybody for me, his voice his age which we have been  told that he is believed  to be over 30 and under 50 and his look,

i have liked him for it since he first appeared please dont hate its just an opinion that im still thinking through and i know i have no evidence for this
