Middle aged Caucasian blonde women are being gunned down on the freeways around Los Angeles. Based on victimology, the BAU determine that the women are surrogates for someone in the unsub's life, probably his wife or former partner. The unsub is feeling emasculated, this feeling onset by some specific traumatic event, but precipitated by perceived attitudes toward him. However, the killings are getting progressively brazen, where the BAU believes the unsub will eventually kill the real blonde woman in his life, and the children associated with that relationship. When the team locate the unsub, it may be too late.
