Bianca Chiverton is the head of the toy company where the murder victim Debbie Cortez has worked. When it was revealed that the owner of the specific model is Bianca it is clear that she must be the killer. Booth and Brennan search her trunk and discover traces of the victim's blood. Bianca explains without Debbie, their stock would've taken a terrific hit. She claims the door striking Debbie was an accident. Brennan points out death would've taken time, so Bianca must've stood there while Debbie expired.
