Criminal Investigations Essay

1.The methods of inquiry is divided into 2 distinct categories. One category is archeologist, historian, journalist, epidemiologist, and criminal investigator. The second category is scientist in general including artist. Fusing these categories together allows the reconstruction of the past. Methods of inquiry use techniques common to both science and art. During an investigation is it important to figure out what took place before the crime was committed to give the police a better understanding of where it took place, why it took place, how it took place and all the events that lead up to the crime.

2.The optimal mindset of an investigator should be open minded and investigative. It is manifested by going into a scene looking at scene from all angles not by having it in your head it was done one way and there is no other possibility. The investigative mindset comes from experiencing it hands on or by practicing. Some people are born with this mindset. An investigative mind gives us the ability to see what a naked eye wouldn’t. It also allows us to see evidence others may not think would be related to the scene. With both mindsets we come in with the questions of who, what, why, when, where?

3. Scientific method is observing, thinking about and solving problems. Investigators will use these methods throughout the entire investigation. Once the investigator arrives on scene they will make note of what they see in regards to bullets, tools, impressions, motive, blood spatter, and how it compares to other unsolved crimes. The investigator will use observation and thinking about the scene to lead him to solve the crime. These methods will also lead to catching the perpetrator. A reason may even be drawn to conclude as to the cause of the crime.

4. The primary sources are used to reconstruct the past and the events leading up to the crime. The sources are records, physical evidence, and people. The people may be victims or eyewitnesses of the crime. The records would be use of stolen credit cards, forged checks, or ransom notes. The physical evidence would be shoe impressions, tool impressions, if barefoot it would be foot impressions, fingerprints, fibers or hair. People can be of value as well. They may know a wealth of information as to who committed the crime, the location of the perpetrator. They may be able to lead you to a person of interest. If nothing else the can give you valuable evidence such as a description.
