Jennifer Jareau: He 's criminally sophisticated and methodical , concealing his method of ingress and egress , leaving little evidence behind in the sniper perches .
Alex Blake: This suggests a great deal of experience , so this unsub has a military or a law enforcement background , possibly even Special Forces .
Dr. Spencer Reid: His victims at first to be targets of opportunity , but it now appears that one or more of them are targets of choice . The remaining victims were collateral damage to be used as a forensic countermeasure ; similar to what John Allen Muhammad and Lee Boyd Malvo did with the D.C. sniper case in _ 2002 _ .
Derek Morgan: This means there 's some unknown connection between one or more victims at the first and second crime scenes .
Agent Tanya Mays: What about the Caucasian male that an eyewitness saw at the plaza ?
