A DANGEROUS INVESTIGATION LEADS THE CSIs TO LOSE ONE OF THEIR OWN, ON THE THIRD-SEASON PREMIERE OF "CSI: MIAMI," MONDAY, SEPT. 20 ON THE CBS TELEVISION NETWORK

"Lost Son" -- The CSIs lose one of their own when a murder investigation turns deadly, on the third-season premiere of CSI: MIAMI, Monday, Sept. 20 (10:00-11:00 PM, ET/PT) on the CBS Television Network. Duane Clark directed the episode written by Ann Donahue, one of the series' executive producers, and supervising producer Elizabeth Devine.

After a large yacht slams into a major Miami bridge, the CSIs find that the man steering the boat was shot and killed. The victim's wife reveals that their son had been kidnapped and her husband had gone to pay the ransom with $3 million worth of jewels. When Horatio's investigation leads them into a dangerous situation at a jewelry shop that may contain crucial evidence, he must face the unimaginable when one of the team is killed in the line of duty.

CSI: MIAMI is a fast-paced drama, inspired by the top-rated series "CSI: Crime Scene Investigation," that follows a South Florida team of forensic investigators who use both cutting-edge scientific methods and old-fashioned police work to solve crimes. Horatio Caine (David Caruso), a former homicide detective, heads a group of investigators who work crimes amid the steamy tropical surroundings and cultural crossroads of Miami. His team includes Calleigh Duquesne (Emily Procter), a bilingual Southern beauty with a specialty in ballistics; Tim Speedle (Rory Cochrane), a cocky but disarming investigator who is well connected on the street, and Eric Delko (Adam Rodriguez), an underwater recovery expert who knows all the twists and turns of the Florida waterways. Rounding out the team is Alexx Woods (Khandi Alexander), the no-nonsense know-it-all coroner. Helping Horatio with certain cases is Det. Yelina Salas (Sofia Milos), who was married to his late brother. Together, these investigators collect and analyze the evidence to solve the crimes and to vindicate those who often cannot speak for themselves, the victims.

CSI: MIAMI is produced by CBS Productions and Alliance Atlantis Communications, in association with Jerry Bruckheimer Television. Jerry Bruckheimer, Ann Donahue, Carol Mendelsohn, Anthony Zuiker, Jonathan Littman and Danny Cannon are the executive producers.
