"Gatekeeper" is the seventh episode of Season Nine and the 193rd overall of Criminal Minds.


After a series of victims are found strangled to death in Boston, the BAU looks for a serial killer who likes to keep mementos of the victims, and the team wonders if a common link to the casualties could lead them to the culprit. Meanwhile, the BAU rallies around Rossi when his favorite bar is on the verge of closing.
