The InterviewUpon entering the room with the suspect, many different physical and psychological signs would be evident. The suspect, if actually guilty, would be experiencing high volumes of nervousness, anxiety, and tension knowing that he was about to face the penalty of his crime. If he had not committed the crime, he may still experience these emotions due to the possibility of being wrongly convicted, or tried for the crime.There would be many nonverbal signs clearly visible by the suspect, which would include all areas of the body. When answering questions, he may not look you in the eyes, or even in your direction.
He may over use his hands and wave his arms while talking, which would express high anxiety. Any body part that may be twitching, showing signs of convulsion, and/or the profuse amounts of sweat would be an apparent sign of being nervous.Knowing the information regarding the violent crime, I would enter the interview room in the most calm and professional manner possible. This entrance and environment would only increase his anxiety and eventually his emotions would take complete control of his speech and body. He would either stop all communications, remain silent for the remainder of the interview, or he would crack and explain all details of the crime.The suspect’s eye movements would be one of the key elements during the entire interview and interrogation process. While answering questions, his eyes may shift very quickly from person to person (if more than one is in the room).
This would only cause the suspect to look more suspicious to the interrogators, but also make him feel more nervous. If he responded to questions by looking away, looking at the table/floor, or closing his eyes, may only increase the severity of the following questions. The more the suspect is unable to calmly look the interrogators in the eyes while answering their questions, the more likely he will be held and charged with the crime.If the suspect contains his tension and anxiety long enough to answer questions, he may use persuasive tactics to trick the interrogators. He may answer very calmly and confidently to show that he is in control of the situation and is sure about his answers.
If he stops to think about the answer too long, this may get him into trouble. If the answers are honest and true, he should not have a problem answering questions in a timely manner. A key element during his answer process is how the face responds to the questions. If he is showing a forced smile, or giving unnatural laughs, this would show he has an uneasy feeling with what information he is supplying.
The mouth, eyes, and all portions of the face move together when emotions are experienced; if he smiles, his wrinkles around the eyes should move, too.
