The Blonde in the Game - S2-E4
Character mistake: In season 2, episode 4, when they find the girl buried under the cross, you can see her face, which means she was on her back, because her neck couldn't possibly bend that far around without it being noted by Dr. Brennan later in the episode (which it isn't). Later in the episode, however, Special Agent Booth tells Epps' wife that she was found buried face down. (00:14:15 - 00:17:30)

The Blonde in the Game - S2-E4
Continuity mistake: When Booth and Bones are discussing Helen Majors, Booth gets a phone call and he holds the phone to his left ear with his right hand. In the following shot, he is holding the phone in his left hand. (00:21:05)
Answer: Answering my own question here but, having contacted various people involved in the production of Bones including Kathy Reichs, Hart Hanson, Eric Milligan, and Deirdre Lovegood who portrayed Taffet onscreen I finally have the answer. No-one know how she did it due to her constantly working alone. And she never revealed this information before her death.
