Agent Russell Goldman with the FBI's White Collar Division in San Diego brings a case to the BAU. A con man who he has been following for five years is suspected to have killed Carla Marshall in Miami, Florida. Carla had been in contact with Goldman about the con man, hence the supposed connection to him as her murderer. If the con man is indeed the unsub, Carla is the first known person he would have killed of those involved in his cons. His past cons generally involved using his charm and good looks to gain the trust of women. As the BAU review Goldman's files on the unsub, they find a change in his general lifestyle pattern from his early cons to the most recent. In reviewing the victim's background as well as the unsub's home life, the BAU believe they have a way to track him down. They have to work fast as they also believe that his mental state is devolving where he is becoming increasingly violent and murderous the closer anyone gets to discovering his fraudulent behavior, and the more he himself trips up trying to maintain his several aliases.
