THE FBI PROFILERS INVESTIGATE A MASS POISONING IN A SMALL TOWN IN ORDER TO DETERMINE WHAT THE COMMON DENOMINATOR IS AMONG THE VICTIMS, ON A REBROADCAST OF "CRIMINAL MINDS," ON A SPECIAL NIGHT, SATURDAY, AUG. 12

"Poison" -- Gideon, Hotchner and their team attempt to catch a suspect who has poisoned multiple residents of a small town, on a rebroadcast of CRIMINAL MINDS, on a special night, Saturday, Aug. 12 (9:00-10:00 PM, ET/PT) on the CBS Television Network. Thomas Wright directed the episode from a script written by Aaron Zelman. (Originally broadcast 1/18/06; previously scheduled for an earlier date)

After determining that the suspect used LSD and "ruphies" to poison the town residents, the team must next identify what type of poisoner they are dealing with, such as vengeful or prankster, in order to ascertain his motive. As they piece together a profile, they become certain that the poisoner intends to strike again and set out to stop him before he can claim any more victims.
