John Curtis

The unnamed BAU stalker (real identity currently unknown) is a budding serial killer who has been stalking the BAU since the start of Season Eight.

History
Almost nothing about the stalker who has been following the BAU has been revealed, not even his or her gender (though it's more statistically probable that it's a male). However, he or she has been stalking them for some time, as indicated by the photos he or she keeps. The photos seen in the Unsub's dark room at the end of "The Silencer" suggest that the stalking began sometime after Prentiss' departure, but before Blake's joining the team since there are pictures of the latter, but none of the former. Also, in a photo of Garcia, she is wearing the clothes she wore during the events of the bank robbery in "Hit" and "Run", which may be where the stalker first saw them. He or she is seen again in "The Apprenticeship", taking photos of the BAU during a softball game. The stalker appears to have escalated to murder recently, having copied the M.O.:s of serial killers John Myers and John Nelson.

Modus Operandi
During the stalker's known killings so far, he or she copied the M.O. of Unsubs the BAU team have captured during the course of season eight. The first victim was killed the same way John Myers, "the Silencer", killed his victims, by sewing his mouth shut. The second victim lost his right leg, the same way killer surgeon John Nelson killed his victims. A difference between the stalker and the serial killer he or she copies is that the stalker takes photos of his or her victims, possibly as trophies, and apparently specifically targets blond men.
