When it comes to analyzing the behavior of a criminal suspect, paying attention to body language is key. According to Mark Bowden, details about Rex Heuermann’s character are on display from the start of the interview. Heuermann’s handshake is notably nervous, and he struggles to align his rhythm with that of the interviewer. This may signal an inability to recognize social cues. He may feel a lack of control, leading him to assert dominance when dealing with others. Bowden shared, “All this may hint towards a neurological disorder with either a lack of emotional understanding or an overwhelm of it.”

During the interview, Heuermann’s mannerisms continue to raise questions. While his open gestures indicate confidence, the timing between his gestures and words are off. At one point in the interview, Heuermann brings up an individual of high status, saying, “Meet with the commissioner of Manhattan Building Department.” He moves his chin up in a haughty manner. Bowden says, “This highlights his desire for dominance and control within his social and work sphere.” Bowden also noted that, while this might be totally coincidental, “working with institutions that serve and house at-risk people can be a pattern for predators,” as they have “access to victims with little power or agency” — a likely sign of his desire for dominance.
