BRENNAN AND BOOTH INVESTIGATE THE DEATH OF A YOUNG CHILD WHO MAY HAVE BEEN SEXUALLY ASSAULTED ON "BONES" TUESDAY, JANUARY 3, ON FOX

Brennan, working hard on her latest novel, is enlisted by Booth to help locate and identify the remains of Charlie, a 6-year-old who went missing from a local park. Brennan determines that Charlie was sexually assaulted before he was murdered, which leads Booth to conclude they're on the hunt for a serial pedophile. When the prime suspect is eliminated, Booth and Brennan pay a heartbreaking visit to Charlie's mother, Margaret, to inform her that Charlie's killer is still on the loose. Suspicion creates uncertainty - among even the people closest to Charlie - and Brennan and Booth must investigate all leads, no matter whom the information points to in the BONES episode "A Boy in a Bush" airing Tuesday, Jan. 3 (8:00-9:00 PM ET/PT) on FOX.
