The BAU travel to Lafayette Parish, Louisiana to work on the case of Sammy Sparks, a ten year old autistic boy who is seen splattered with blood. His parents, Alison and Charlie Sparks, are missing. At the Sparks home, the BAU find evidence that Charlie was shot and has a serious wound. The Sparks recently were issued a large loan to be able to keep their music store, their long time family business, open. As Lafayette Parish is in an area hit hard by the oil spill, anyone who gets a loan is considered to have won the lottery. The BAU therefore believe the Sparks were targeted for the money, and that the unsub knew the family and knew that Sammy would not be able to identify him. They try to decipher Sammy's drawings and his music and piece it to the strict routine by which all the Sparks lived to find the unsub. Meanwhile, two of Prentiss' Interpol colleagues, Tsia Mosely and Clyde Easter, try to track Ian Doyle's movements, while Prentiss considers asking her BAU colleagues for help on the matter.
