09E07 - Gatekeeper

The BAU heads to Boston, Massachusetts where three men thus far have been found strangled to death in the downtown area. Each were lower middle class which generally rules out theft as the motive, and some sort of garrote was used in each strangulation. Other aspects lead the team to believe that the killings were not random but that the unsub probably didn't know each of the men personally. In interviewing family and friends of the victims, the team also learns that each victim was well liked despite having a major character flaw, those flaws which may be partly the motivation of the unsub in killing them. The team has not been able to identify the last person who would have seen the latest victim, Scotty Delfino, that person who would have been his latest one night stand. But when a fourth and fifth victim emerges, both who don't quite fit the profile, it is their indirect connection and that to Scotty Delfino that may lead the team to the identity of the unsub and the reason why he feels the need to kill. Meanwhile, Rossi is sad to hear that one of his long time haunts, a bar where he met his first wife Caroline, will probably soon close.
