Investigation Of A Crime Scene

As a crime scene investigator it is their job to collect all of the evidence in a timely manner. Although, there are ways to collect the evidence it is very important to make sure that the evidence is collected correctly and properly. Now as a crime scene investigator I have arrived on a crime scene where there is a lot of evidence that needs to be collected. All of the evidence that needs to be collect for the case is drying blood on the floor, a hand gun, several shell casings near the victim, and some hairs that is still in the deceased victim’s hand. Therefore, I would start by taking pictures of the entire crime scene to ensure that everything is documented as it was found before I start to remove any of the evidence. Furthermore, I would ensure that I am at all times wearing latex gloves so that I don’t leave my own finger

It is imperative that an agency has an evidence collection unit that processes all crime scenes for many of reasons. Securing the scene, separating the witnesses, scanning the scene, seeing the scene, sketching the scene, searching for evidence, and securing and collecting evidence are the seven S’s of crime scene investigations in which an evidence collection unit is in charge of last three (ECU, 2017). The biggest advantage to having an evidence collection unit is that highly trained and certified personnel are the ones who are systematically and properly sketching the scene, searching for evidence, and securing and collecting evidence. Another advantage of having an evidence collection unit is that they have all the proper tools and supplies

Since the time that the scientific science dramatization "CSI: Crime Scene Investigation" turned into a tremendous hit and generated its fans, reporters have been worried about what they instituted the "CSI Effect." The hypothesis behind the effect is that fans of the well-known show disguise misguided judgments about the law that they bring with them into the court as jurors. In this way, the trepidation is that the TV show is at last influencing the results of trials - and not in a great manner. Criminal justice researchers have started to study the inquiry of whether nationals who are called to serve on juries bring unreasonable desires and convictions to the court as a consequence of TV projects. The impact that these projects may have on the jurors, their desires, and their choices is known as the CSI effect.

Like you see in the Crime scene investigation shows like CSI and Bones, there are many things that go into investigating shows a lot of those things happen but it takes much longer than forty or sixty minutes to solve the crime. While crime scene investigating is very serious job, collecting evidence at crime scenes requires education and knowing of what you're doing, requires hard work, and it can be difficult to perform this job.

This information will help investigators cluster the symptoms with a particular disease and rule out irrelevant information. The surveillance of the components gather in this step will put a perspective on the abnormal health events that are occurring on the outbreak timeline.

Crimes scenes contains more information than what meets the eye. This information is gathered based off of evidence left behind by a criminal offender. The Federal Bureau of Investigation’s (FBI) Behavioral Science Unit (BSU) has be around since the 1970’s. BSU experts develop criminal profiles based on the thorough examination of evidence and information gathered in reference to a specific crime. The FBI’s Crime Scene Analysis process involves six steps. These steps are Profiling Inputs, Decision Process Models, Crime Assessment, The Criminal Profile, The Investigation, and The Apprehension. These six steps play a vital role in the process of creating a criminal profile.

A crime scene analyst (CSA)), also known as a crime scene investigator or forensic science technician, supports police detectives or other law enforcement investigative teams by locating, collecting, and possessing evidence.

There are various things that can be resolved taking into account the intimations that are deserted by the criminal. These help the specialists comprehend things, for example, what sort of individual they are and distinctive inspirations just to give some examples. The BSU or Behavioral Science Unit from the FBI has been helping state and neighborhood law implementation organizations with wrongdoer profiling following the mid 1970's. This foundation was made in Quantico Virginia at the FBI Academy [ CITATION Sta157 \l 1033 ]. Based upon the exhaustive examination of the wrongdoing scene the BSU could create and utilize a sensible technique keeping in mind the end goal to recognize wrongdoer attributes.

On September 30, 2015 at 8:25, a 911 caller, identified as Mr. Kenneth Ross/Witness #1, reported he found the body of a black male lying face down in the park near his home with blood all around him and he appeared to be deceased. Witness #1 reported the body was located in Woodbury Park adjacent to Wilson Drive in the Pineview neighborhood. The body was near a park bench on the west side of the park. Dispatched at 8:30 a.m., I arrived on scene at 8:45 a.m. and immediately initiated my field notes, began cordon procedures, initiated searching and identifying evidence, identifying possible witnesses and notified the dispatcher to contact the city coroner and have them respond.

July 1986 - Allan Dakin, 50, is bicycling toward his favorite fishing spot. He stops at a flooded irrigation ditch and works his way down to check his crawdad traps when he spots a young blond female, floating in the water face down. He panics, heads home to notify authorities. Sheriff deputies and local fire department respond first to the scene at 8:45 am, and push the body using a long gaff to the opposite bank where the victim will not drift downstream.

. Listed were searches on how to make homemade chloroform, how to do a “fool proof” strangulation, and how to get rid of a body. (Casey Anthony Case, 2013) It is not clear who actually made these searches. Cindy admits she was trying to look up chlorophyll and ended up searching for chloroform by mistake. All in all, this seemed unlikely to investigators but they did not have the definitive proof needed to charge anyone. At this time they still only had Casey as a person of interest. The entire family refused to take a polygraph test.

Many forensic photographers begin their careers as police officers or crime scene investigators, or they may have degrees in law or criminology before undertaking additional training in forensic photography.

The first is the preservation of the crime scene. If the crime scene has not been secured and borders not set up this will result in the contamination or loss of physical evidence, which is crucial in a reconstruction. The second is an investigator is the use of inductive and deductive reasoning, not have any preconceived ideas) by using the facts of the case, in addition to photography, video, crime scene sketches, and other documentation to draw inference (M.U.S.E. (2), 2017)

DNA evidence can come from the suspect themselves or found at the crime scene. If the investigator does not know who was at the crime scene, they can collect different forms of DNA. The investigators can collect liquid blood, bloodstains, saliva stains, liquid saliva, liquid semen, or dried semen (“DNA Evidence Basics: Types of Samples Suitable for DNA Testing.”). Different forms of DNA can appear on any surface. They can even find hair follicles, fingerprints, and fingernail clippings. Then the investigators can use that evidence to narrow their search for the suspect. If the suspect is known, the investigators can use different forms of evidence to connect the dots. The investigators can do an oral swab, collect blood samples, and pluck hair (“DNA Evidence Basics: Types of Samples Suitable for DNA

In documentation of the crime scene, the investigators were quite effective in documenting the crime scene. The proof of this documentation comes in the level of care that the evidence and its details were kept years after the incident. For example, the bloody T-shirt, which could provide Pam’s DNA along as with the attackers was well kept and labeled that it hardly escaped Carl’s team. Also, the gun, which was the main weapon used in the attack was kept well enough to the extent that details about the ballistics and GSR reports conducted in determination of whether it was a murder or suicide were intact seven years later. This level of documentation is very significant
