Aaron Hotchner:  We believe whoever poisoned these people was motivated by revenge .
Derek Morgan: The randomness of the victimology , average people in an average - sized town , all points to a local resident .
Elle Greenaway: We know that people who poison for the purpose of revenge primarily act alone .
Aaron Hotchner: However , he may have manipulated someone close to him to assist him . The unsub usually disposes of these accomplices when they are of no further use to him .
Elle Greenaway: The unsub is likely a cautious , deliberate , and highly functioning male between the ages of _ 35 _ and 50 .
Aaron Hotchner: He chose LSD for a reason . LSD is about altering perception . We think that this unsub is striking out because he feels that 's he 's been inaccurately perceived by the community , or a subset of it .
Derek Morgan: He feels that these attacks will affect and alter a reality that he is caught in , that he perceives to be unjust .
Aaron Hotchner: He 's so self - centered , he believes his victims will know the reason for the attack and who did it .
Dr. Spencer Reid: This individual was savvy enough to use Rohypnol to obstruct our investigation , erasing the memories of the victims of how they were poisoned .
Detective Hanover: Hold on . If this guy believes that his victims know who he is , why is he covering his tracks ?
Jason Gideon: Because these victims are n't his primary targets .
Aaron Hotchner: We ... we know from precedent that this kind of offender , the avenger , tests his weapon first . This attack was a test run .
Detective Hanover: A test run for what ?
Aaron Hotchner: We do n't know yet . What we do know is this is not the first time he 's aired his grievances . While it 's not likely that he has a criminal record , it is possible that he has filed criminal charges , or pursued a civil action against his perceived adversaries . And now , to measure the results of his test , he 's watching .
Jason Gideon: And he wants to see the results of his test . Once he has them , all those years of pent - up rage will be unleashed in the form of a larger attack . Profile indicates a lot of people could die .
