Example Input: Aaron Hotchner: The unsub we 're looking for is a dangerous voyeur , who feeds off the thrill of knowing his victims ca n't see him .
Dr. Spencer Reid: Typically , voyeurs are non - violent and content to remain bystanders . This _ one _ is different ; he 's on a mission that includes taking action .
Aaron Hotchner: And in that mission , he did n't hesitate to kill a teenage boy . Anyone who stands between him and his goal is at risk .
Alex Blake: We believe he 's documenting his work . He 's taking pictures and collects personal connections to his victims ; their wallets and their hair .
David Rossi: It 's important to him to have proof of what he 's doing .
Derek Morgan: Voyeurs like to create fantasies in their heads of what the objects of their obsession should be like .
David Rossi: He creates a character identity instead of a reality , and when a person steps outside of the parameters that the unsub has set for them , he strikes .
Jennifer Jareau: This unsub appears to be triggered by males acting on what he perceives to be character flaws . Seemingly innocuous infractions to us are magnified in the unsub 's psychosis .
Aaron Hotchner: Based on the planning and sophistication of the kills , we believe that he 's in his late thirties or forties .
Dr. Spencer Reid: The geographic profile tells us this unsub is not only dumping his victims downtown , he 's hunting there , too .
Derek Morgan: So this is where we need to redouble our efforts . Go building to building , door to door . This guy 's a fly on the wall ; he 's able to leanr secrets without anyone realizing he 's there .
Alex Blake: He 'll have a job that involves very little social interaction , but that puts him in a position where he can observe others unnoticed .
Jennifer Jareau: So we should look at service workers , groundskeepers , anyone paid to be invisible .
Aaron Hotchner: And we need to move quickly . This unsub is approaching some sort of perceived deadline . The closer it gets , the more erratic and dangerous he 'll become .
Example Output: voyeurs
