Synopsis:
Booth and Brennan examine the remains of a woman and fetus found in the Delaware Bay. The body is identified as that of Carlie Richardson, a pregnant newlywed whose mysterious disappearance one year ago had been a major national news story. Carlie's husband Kyle Richardson is immediately thought to be the prime suspect in the case, but he disappears before Brennan and Booth can question him, prompting Booth to call for a manhunt for Kyle. Clues found with the remains throw suspicion in a different direction, and Brennan enlists Booth and her team at the Jeffersonian to recreate the potential scene of Carlie's murder to get a better idea of the build and body type of the murderer, with shocking results. Meanwhile, Booth is annoyed that his ex-girlfriend Rachel, the mother of his son Parker, is letting Parker spend so much time with her new boyfriend, forcing Booth to be more territorial than Rachel would like.
