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

    In food it is common to use Nisin at levels depending on the food type regulatory approval. Nisin cannot be produced chemically therefore it has to be synthesised using fermentation. During fermentation various stages of growth occur and as a result different conditions can occur during this fermentation process, eg pH, most organisms produce acid as they grow and therefore in the Lag phase ( a period of adptation for the cells to their new environment, new enzymes are synthesized) and in…

    Report on the Reaction of Flames Towards Medals  Introduction The purpose of the flame lab was to identify a set of flame-test color standards for selected metal ions, relate the colors of a flame test to the behavior of excited electrons in a metal ion, observe spectral lines using diffraction grating, and to identify an unknown metal ion by using a flame test. My hypothesis for the lab was that most of the flames when sprayed with a solution will be a orange-red color. The unknown element…

    My lab results were similar to my hypothesis. My hypothesis was that the densest object would be the rubber stopper. In the lab results the densest object was the penny and the rubber stopper was second. My hypothesis was switched. My hypothesis was correct when I stated that the macaroni was the third densest object. My hypothesis was also correct for the dice, but the bead and the dice share the same density. So they are both the fourth densest item. I was wrong with my hypothesis when I placed…

    Each element emits a unique color light. The purpose of this experiment was to observe these unique colors and calculate their energy. In order to observe this, we placed the physical elements in a 24 well plate, dipped wet q-tips into the wells to gather the element, and put it over the bunsen burner to observe the flame emitted. While observing the different flames, we saw that different elements did indeed emit unique flame colors. Colors such as red, violet, and turquoise were emitted. All of…
