Elizabeth Vogel

Dr.  is a woman in her forties and is a specialist in genetic inheritance in behavior.

Jacob Barber met with Dr. Vogal weekly for a series of tests to see if Jacob had any genetic predisposition to aggressive behavior. This was important as any evidence may have lead to Jacob's prison sentence being reduced to should he have been found guilty.

Due to Dr. Vogal's expertise, Laurie Barber visited her in her moments of need when she felt doubt over whether her son may have committed the murder of Benjamin Rifkin. In particular, Laurie recounted times in the past where Jacob as a child had not been 'normal' and had been aggressive at times. Dr. Vogal reassured Laurie that children can sometimes act like that and that did not make Jacob a unique case.

At the end of the weekly sessions with Jacob, Dr. Vogal called a meeting with Andy Barber, Laurie, Jacob, and Joanna Klein to discuss the findings in her report. She found that Jacob did not possess the murder gene which William Barber and Andy possess. It was found however that Jacob possesses genes linked to a lack of empathy and also violent tendencies in adolescence, as do William and Andy. This caused Laurie distress and she asked Dr. Vogal if this meant Jacob could have committed the murder and if Dr. Vogal thought he did. She could not provide an answer.
