PS2200 - Criminal Investigation
Unit 04 Assignment 01

As the lead homicide investigator for this case I had recently learned that the crime lab has concluded that the finger print that was recovered belonged to the boyfriend, they were from a piece of notebook paper found under the body of the victim. Interviews are conducted in criminal cases for the purpose of gathering information from people who have, or may have, knowledge needed in the investigation. (Swanson, Chamelin, Territo & Taylor, 2012) However with the information that was recently learned from the evidence that was collected and analyzed by the crime lab, the interview with the boyfriend would now be conducted as an interrogation. Interrogation as opposed to interviewing is designed to match acquired information to a particular suspect in order to secure a confession; it is the process of testing that information and its application to a particular suspect. By means of interrogation we would be able to eliminate the innocent or identify the guilty. (Swanson, Chamelin, Territo & Taylor, 2012)
There are circumstance’s where the investigator may go directly from an interview to an interrogation occurs when the suspect exhibits a clear indication of wanting to confess during the interview. This could possibly occur early during an interview when the suspect becomes confused, attempting to change his alibi or perhaps when he is asked a question such as “why where your prints located on a piece of paper underneath the body of the deceased victim)?” and the suspect puts his head down and simply shakes his head implying a denial. At any moment an interview can become an interrogation, there are situations where an investigator may go directly from an interview and into an interrogation, or take a pause between the two.
The investigator could step out of the room for a few minutes to review his notes, review the case file, and talk to another investigator or to make a

    1. The Respiratory exchange ratio is the ratio of the volume of carbon dioxide produced and oxygen consumed. The ratio indicates the energy that the subject is expending for indirect calorimetry, how efficient the subject 's body is at utilizing the oxygen inhaled, as well as the main substrate being used for energy during varying intensities of exercise. During rest the volume of carbon dioxide was 0.73L/min, the volume of oxygen was 0.84L/min. The RQ or RER was 0.87. Based on Table 5.1(Kenney,Wilmore, &Costill, 2012; Physiology of Sport and Exercise(5th ed.) The ratio indicates that roughly 68% of the kcal that the subject was using came from carbohydrates and the remaining 32% of the kcal came from fat. During the 50W stage the volume of carbon dioxide was 2.2L/min and the volume of oxygen was 2.9L/min. The RQ was 0.79, which indicates that the 33% of the kcal that the subject was using came from carbohydrates and that 67% of the kcal came from fat. In the 100W stage the volume of carbon dioxide was 4.08L/min and the volume of oxygen consumed was 4.1L/min. The RQ came out o be 0.99, the substrate being used was only carbohydrates at this point. The 200w stage had a carbon dioxide volume of 7.91L/min and a oxygen consumed volume of 6.51L/min. The RQ was 1.2 which indicates that the body is producing more carbon dioxide than the oxygen being consumed. The substrate being used for energy again is only carbohydrates.…

    The following report will describe both my journey to find my unknown as well as the results that led to my discovery. Before I start, I will say that I am 100% positive that my unknown (which was #31) is none other than Proteus vulgaris. My data and the ensuing results from them simply cannot be disputed. From my first batch of results, Proteus vulgaris reared its head and I had it figured out, but needed the second half to prove my hypothesis correct. It was in fact my discovery that led to the class announcement that the Gelatinase test results for Proteus vulgaris was incorrectly labeled on the table. The following information will be regarding the data that guaranteed my assumption:…

    Being cautious and prepared is key for interrogating suspects. The interrogation location should be free from distractions or interruptions. The interrogation room should be well lit and secure. It's important that the officer not ask close ended questions. Asking closed ended questions will lead to short yes or no responses. Asking open ended questions will lead to a broader response and more information will likely come out. Taking notes and recording the interrogation is also key. Although there are many types of interrogation techniques, the officers should discuss the role they will be playing before hand. They can decide which type of interrogation technique will bring out the best results. -WRITTEN AND INTERPERSONAL COMMUNICATION-METHODS FOR LAW ENFORCEMENT By Harvey Wallace and Cliff Roberson(CHAPTER 9 PAGES 139-145)…

    In unit 7.3 the experiment tested the ability of lactase to specifically bind and interact with lactose compared to maltose. In unit 7.4 the experiment tested the role, if any, that metal ions have on the activity of lactase. My hypothesis for unit 7.3 was knowing that lactase is specific for lactose, lactose will separate into galactose and glucose, as maltose will not change (153-155). Lactase should like lactose. For unit 7.4 my hypothesis was that EDTA will remove the ions, and will not work.…

    In the article “How Boys Become Men”, written by John Katz, he analyzes situations he experienced while growing up. Katz believes that boys become men by not showing fear or feelings and not ratting on others. As in the novel, The Other Wes Moore, both Weses are forced to become men at an early age. They experience events that push them to make decisions that make them grow and think like men do. Katz details the maturation process for boys, as the book, The Other Wes Moore, does with both Weses. They make decisions and take actions to mature and become a men.…

This would determine the relationship between the victim and the suspect, if he or she knew the suspect very well, in passing, or if he or she were just an acquaintance. Asking the suspect where he or she was during the time of the crime determines an alibi. After the questioning is completed, based on the answers he or she is either let go or detained until further notice from the…

    The SIP interview is a recently developed ideal interview based on the same five stage PEACE guidelines and most updated techniques. However, for the purpose of this study not all stages were used as they hold little relevance outside a real life forensic investigation (i.e. planning and preparation, and evaluate). The engage and explain, account and closure stages were used, but slightly adjusted to match the context of this study. Thus, the administration of the SIP interview included rapport-building, appropriate and clear instructions, the predominance of open questions (e.g. ‘’Tell me more about X, Y, Z’’), no interruptions, the focus on mentioned topics, appropriate structure and closure. To ensure consistency between interviews, the administration of the SIP interview included two follow up questions on a topic already mentioned by the participant in relation to location, action or people’s description. Moreover, all participants were encouraged to add to the interview by being asked ‘’Is there anything else you would like to tell me?’’. Before starting the interview process with participants, the experimenter undertook three days of SIP technique training by the main creator of the protocol, Dr Fiona Gabbert. The SIP template used in this study can be seen in Appendix…

    The author David Simon writes an informative article on the topic of a homicide unit in Baltimore. He writes this to let the citizens of Baltimore know how interrogation works. His book, Homicide: A Year on the Killing Streets gives us a very detailed view on this. Homicide detectives work hard to get information out of suspects. They like to give their suspects a false hope of becoming free if they give up the info. They call this hope an imaginary window, an escape hatch in which they might be able to crawl out of. When done correctly the detectives can get all the information they need from the person. The guiltiest person is constantly the first person looking for an out; after all, if you’re not guilty what are you scared of? The interrogation is closely related to a performance, it that helps the detectives get “common ground” with his suspects when non-exist. When a suspect gets comfortable, he/she is more likely to talk. This “performance” is highly important because in Baltimore, a…

    Majority of interrogators follow the Raid Interrogation method due to its high effectiveness. The Raid Interrogation procedure involves isolating the suspect into a confined room, confirming that there is no doubt in his or her guilt, preventing the suspect defending his or her accusation, lying about evidence that proves their crime, giving the suspect reasons on why he or she committed the crime, repeating the steps until they agree with you and having them provide the details about the crime (Jackman Para. 8). James L. Trainum is a former detective who spent 17 years in homicide and dealt with interrogations around it (Jackman Para. 3). He didn’t recognize the flaw in the interrogation method until he realized an imprisoned woman that he previously interrogated was exonerated through DNA examinations.…

    The Reid technique is a commonly used police interrogation technique in North America (King & Snook, 2009). This interrogation technique is used to elicit confessions from people suspected of committing a criminal offense. The Reid technique requires that police officers collect factual evidence, then the interviewer questions the suspect in a non-accusatory manner (King & Snook, 2009). Truth or deception is then determined based on behavioural analysis of the suspect, then if deception is detected a 9-step psychological approach from the Reid technique is applied (King & Snook, 2009). However, interrogators often apply this technique as the first step without any physical evidence, where they coerce their suspect to incriminate themselves…
