Emma Yates UNIT 39: From Crime Scene to Court It is the job of the FSI to find and collect evidence left behind by offenders on the crime scene. Using the latest forensic techniques they look for all sorts of evidence. The FSIs follow several procedures. To stop potential evidence being destroyed, lost or contaminated they preserve and protect the crime scene. FSIs then start to work with the investigating officers.

The totality of circumstances provides that one must look past each individual aspect of the scenario and look at the scenario as a whole. In Officer Smith’s case, with the absence of a broken taillight, one must consider that, even though the light was not broken, Officer Smith still would have had lawful reason to pull the vehicle over since it matched the description of a vehicle in a previous murder case. Even though this car was not the vehicle involved, the driver gave the Officer probable cause to believe that it could be by fleeing the scene. With the totality of circumstances considered, I believe the entire scenario would be found
The lead profiler on any case can be someone from within or outside the department depending on the skill levels available internally and preferably, a teamwork approach to case analysis would create a continuing dialogue that would not entirely hinge on the opinion of one investigator or profiler. While it is desirable to narrow the suspect list down to a workable size for the investigators, it is also necessary to prevent personal whims from causing tunnel vision and causing the exclusion of viable suspects. The four basic skills necessary for good Investigative Criminal Profiling - investigations, forensics, psychological assessment and the application of cultural anthropology - are necessary to a complete an accurate profile. It should be recognized that experts should be consulted to fill in the gaps. A homicide investigator with limited skills in profiling might combine his skills with that of a professional profiler and as a team, increase the success of the
Duplicate secrets will come in helpful in case of an urgent situation, like locking your secrets in your car. In most cases the car dealership where you purchased your automobile is able to make repeat keys after request. Just about all local locksmiths will also be able to make duplicate keys for your automobile. Both of these options require that you show your original keys up front, so it is important to start this before you lock your keys in your car or lose them. Keeping duplicate secrets is a good precautionary measure to make certain you will not be stranded if you lock your secrets in your car.
Documents Deborah Marie Wood CJ386-01 – Forensic Biology and Impression Evidence Professor: James Jabbour, MSFS April 26, 2011 Forgery is not only a criminal activity but involves much civil litigation as well. A document examiner can take a questionable document and samples of handwriting to determine if the document has been forged or not. A document examiner can also use several other methods to determine to validity and authenticity of the document in question. A document examiner can also tell if portions of the questionable document had been altered or changed in any way. With proper collection and techniques a document examiner will be able to determine the questionability of any document without a doubt.
From this type of profiling an offender can be categorized as organized nonsocial offenders and disorganized asocial offenders. The killing from theses two types of offenders would produce two different crime scenes, one of complete chaos and plenty of evidence all over and another with little evidence and more controlled. A major benefit from using this type of profiling is that it let investigators know what kind of offender they will be dealing with so they know how to proceed with the case and interrogate them. A limitation from this type of profiling can be that too much attention is paid to the physical evidence and not on the nonphysical (Holmes & Holmes,
Before the lineup is done, whether physical or photo, you have to explain to the victim/witness that the purpose of the lineup isn’t only for identification but to also exonerate the innocent. (Technical Working Group for Eyewitness Evidence, 1999.) After the photo or physical lineup, is to interview the victims/witnesses and take down their account of what happened. This is called a statement. During the interview it is very important to build good rapport and listen very carefully.
“Utilizing polar coordinates is the fourth method of crime scene mapping used to document evidence location at a crime scene. Like those previously mentioned, this is a two-dimensional system that indicates the location of an object by providing the angle and distance from the fixed or known point. Obviously, in order to conduct measurements by this method a transit or compass is necessary to measure the angles and polar directions. This method is best utilized in large outdoor scenes with very few landmarks (e.g., a plane crash in forest or large field).” Each technique has a great amount of effectiveness some more than others, but either way they all help to determine the different dimensions of a crime scene. The process of each one is not like a draw the scene and bam you’re done.
Shameka Adams Criminal Investigations Everest Online Criminal Investigations In criminal investigations, officers must document everything. They must take notes and photographs of all facts and evidence found at the scene. Describe the importance of not-taking, particularly in the integrity of the crime scene? Notes are vital throughout the entirety of the investigation. Notes are brief records of what was seen or heard and are important because if detailed enough, they can make or break a case (Orthman & Hess, 2010).
