THE CSIs INVESTIGATE THE MURDER OF A HIGH SCHOOL STUDENT FOUND DEAD ON A GOLF COURSE FOLLOWING A "FLASH MOB," ON A REBROADCAST OF "CSI: MIAMI," MONDAY, DEC. 20

"Murder In A Flash" -- Following a flash mob on a golf course, the dead body of a high school student is discovered and the CSIs must find the killer, on a rebroadcast of CSI: MIAMI, Monday, Dec. 20 (10:00-11:00 PM, ET/PT) on the CBS Television Network. Fred Keller directed the episode written by Anne McGrail and Susan Nayar. (Originally broadcast 10/11/04)

E-mails and text messages trigger a mass gathering of students to perform a random task on a golf course; however, as the crowd disperses, the body of a high school student is found. The original message triggering the "flash mob" is traced to a high school senior whose father is a high-powered defense attorney. However, the case changes direction when Horatio and the team learn that the schoolmaster's daughter may have had something to do with the murder and evidence reveals that the victim was having an affair with his chemistry teacher.
