07E21 - Divining Rod

Moments after serial killer Rod Garrett is executed by firing squad at Gunter State Prison, another person kills in Enid, Oklahoma where the prison is located. The victimology and M.O. are the same as in Garrett's killings - female, young, blonde, pretty, and killed with a single stab through the heart using an ice pick. By the time the BAU arrive on the scene hours later, the unsub has killed a second victim - same victimology, same M.O. Garrett is survived by his wife, Helen Garrett, who stood by her husband's side through his incarceration, since he stood by her side when she went through a life threatening illness years prior. When the unsub kills a third victim, the team notices slight differences between Garrett's killings and the latest killings, as well as there being a regulated time schedule to the recent murders. Those differences, information from Helen about herself and about fans of her husband's, and the geography of the latest killings provide clues as to the unsub's identity and his motivations for following in Garrett's footsteps. Meanwhile, Prentiss awaits news about an offer she placed on a house, which she seems nervous about getting.
