On October 30, 2014, a frightened eleven year old Joshua Parker is found at a Halloween fair in San Diego. He went missing on Halloween day the previous year. His case mimics that of Tommy Wilcox, who went missing on Halloween 2012 in Los Angeles, only to be found on Venice Beach October 30, 2013, alive but he who eventually died of malnutrition a few hours later. Joshua, however, is expected to live. Both boys had atrophied muscles, and had splinters and puncture wounds, although Joshua seems to have been fed somewhat properly. Both boys were also considered troubled, Joshua who was never listed officially as missing since he was a chronic runaway. The problem for the BAU is that Tommy's captor, Rodney Tanner, who confessed to the crime, is currently incarcerated, meaning that he either had a partner, there is a copycat loose, or that his confession is a lie. They have to figure out this issue before another troubled early or pre-teen Caucasian boy is abducted in the next day. Reid comes to the conclusion that the boys were housed in a homemade wooden box, which accounts for all their physical issues. Discovering a case similar from the past of boys so confined, especially as it relates to Halloween, may provide clues as to the identity of the unsub.
