The Homicide unit assisted both the investigators and the Forensic Identification unit to gather enough evidence to determine what happened at the crime scene (Huff Post News, 2013). The Forensic identification unit assisted the investigators in determining if the remains that were found in the incinerator, was in fact of Tim Bosma. The forensic scientists evaluated a tooth that they had found, to see if they could gather enough DNA from it to positively identify the human (Adam Carter,
Their findings, in turn, will affect the course of the police investigation and, if a suspect is charged,
After inspecting the murder scene investigators
Trace evidence investigators would definitely benefit from these aspects. The investigators can link a suspect and a victim to a certain location through trace evidence. Also, trace evidence is an advantage because you can find DNA evidence. For
The psychological profile on the murders is the most important part of the case since the killer was never caught this profile can create a connection to suspects through their
Evidence found at the place of the crime can give investigators clues to who committed the crime. For example, investigators can find footprints, fingerprints, or even the murder weapon.

In a scientific evidenced-base practice, it is showing that there are many risk factors that predispose certain individuals to development of diabetes. To deter these people, screening the population who at risk of developing a chronic disease like diabetes would play a serious role not only. Early identification and intervention of pre-diabetes and diabetes can prevent or delay the onset of diabetes, and reduce the incidence of diabetes-related
Criminal investigation is the process of discovering, collecting, preparing, identifying, and presenting evidence to determine what happened and who is responsible The preliminary investigation includes all the activities that an officer performs when he/she responds to a crime. The officer is responsible for responding immediately and rendering aid to those that are injured. While the officer responds and renders aid, it is important for he/she to note important facts by either writing it down, contacting dispatch, or taking mental note. These facts include the position of the victim or injured, recording spontaneous statements, paying attention to unusual actions or activities, and an assessment of the crime scene. I know it is out of order, but I believe the second and most crucial step is to secure the crime scene.
Lastly, their brain activity can give detectives an accurate picture of how they think which can help determine their motives for the killing or their next potential victim. With
The assistant in the crime scene investigation has the role to assist the CSI with the measurements and finally the report may be revised by the same for any corrections if he thinks is required in the document. Carrying out a Complete Enquiry A detailed search is required at the crime scene as the next step of investigation. Each nook and corner of the location must be revisited by the CSI in order to get even the smallest piece of evidence, if any. Many crime scenes use an evidence vacuum in the scene for collecting any micro particle as evidence such as hair and fibers which may become a useful link to the culprit.
The techniques used by the Scientific Expert range from crime scene investigation to giving expert testimonies in courtrooms. Some techniques that are used in crime scene investigation which rely on scientific method include finger print analyses and collecting DNA samples (Liu, 2009). However, using the scientific method regarding the effectiveness of a proposed policy is different. When a new policy is proposed, the Scientific Expert gathers information on said policy such as where the policy has been put into place and compares crime rates before and after it was enforced. Depending on the evidence that is drawn, state or local government look into the policy and make an educated decision concerning whether or not this policy will be successful in the given area.
Science has come a long way over the years. It has helped countless every day struggles and cure diseases most commonly found. What you don’t hear about however is the advancement of forensic science. Forensic science has helped solve countless cases of murder, rape, and sexual assault. In the case of John Joubert, it helped solve the murders of three young boys with one small piece of evidence that linked him directly to the crime.
The first thing that criminal profilers do is go to the crime scene and gain information about the crime scene, such as such as pictures and information about the area. While at the crime scene, they are being to try to put themselves in the mind of a criminal to see what they maybe feeling or thinking. There are 4 main things that they look at to gain information about the criminal, the antecedent, Methods and manner, body disposal and the post offense behavior. (Winermen). They evaluate the information and start to form their profile from the information.
so they have an accurate description of the suspect, which can lower the amount of unsolved cases, and provide video footage
The scientific method is a way to make sure that all responses are accurate and reliable. It helps us to have clear goals. The Scientific method consists of repeatable and observable evidence which help with achieving solutions in any aspect of one's life. Scientific methods always start with a question in response to some natural curiosity or observable anomaly. Once you know the question, you should start gathering previous research from other scientists and using it as groundwork to rely on.
