Crime scene investigation is a field with rapidly changing tools that seem to evolve almost every day as a result of the changes made in technology. However, even the simplest elements of a crime scene can still inform investigators an epic amount.
For instance, in this case, the position of the body and the weapon used represent the main forms of evidence and can help investigators uncover the elements which motivated the crime and caused it to happen. "Firearms evidence is usually encountered in crimes against persons such as homicide, assault and robbery; but may also be found in other crimes such as burglary, rape, and narcotics violations" (crime-scene-investigator.net). Thus, the very fact that this crime scene even involves a rifle means that there is a strong likelihood that it was a violent crime and that the victim was a murdered and that the case is a homicide. However, this is not definitive. Research demonstrates that when it comes to guns, suicides make up the bulk of deaths. "Suicides accounted for 55% of the nation's nearly 31,000 firearm deaths in 2005, the most recent year for which statistics are available from the Centers for Disease Control and Prevention… There was nothing unique about that year - gun-related suicides have outnumbered firearm homicides and accidents for 20 of the last 25 years. In 2005,...
Accidents accounted for 3%. The remaining 2% included legal killings, such as when police do the shooting, and cases that involve undetermined intent" (CBS, 2008). In that sense, it has called public health researcher to determine that in homes where there are guns, the likelihood that a person in the home will die from suicide or homicide is at an aggravated likelihood. This indicates that in this case, statistically, it is likely that the man turned the rifle on himself, firing at himself in the head. This is supported by the fact that in the room there is no sign or break in or forced entry: none of the windows are open or broken and none of the doors are open or compromised in any way. However, this doesn't mean that someone couldn't have broken in. This particular room was widely accessible: there were four doors surrounding the perimeter of the room and two windows. There is no evidence or any other signs which indicate that the victim locked himself in. However, while there is compelling evidence in this case along with historical evidence to support the idea of a strong suicide, the placement of the weapon negates this fact.
Moreover, in this case it would also be worth examining the shot wads which were involved, although they're not visible here. "When a shotgun…

Crime Scene Investigations: Many crime scene investigations revolved around safeguarding the crime scenes, protecting physical evidence, and gathering and transferring the evidence for scientific evaluation. This process is based on the role that physical evidence plays in the overall investigation and determination of a suspected criminal activity. Notably, the ability for physical evidence to play its role in the overall investigation process is dependent on actions that are taken early enough
The may differ considerably. In fact smaller agencies may not require a degree, while a degree will usually be required with larger metropolitan agencies. (How to become a CSI) Conclusion In conclusion, a central aspect that research into this field reveals is that Crime Scene investigation differs considerably from the popular media presentations. CSI is a complex sector of criminal law enforcement and is characterized by the input form various specializations
computer related data on a forensic level. With new advances in technology, there are new opportunities for criminals to commit crimes online and through hacking into computer systems. These crimes committed are often very complex, and take special techniques in order to collect enough evidence to suggest a suspect or even the presence of a crime itself. The paper then goes on to discuss the sensitivity of electronic evidence
Crime Laboratory After Bartos's (2012) PBS Frontline story ran, exposing illegitimate online forensic credentialing programs, law enforcement agencies and private crime laboratories became aware of the need for improved human resources departments and more robust candidate screening programs. Given the proliferation of bogus online accreditation systems, human resources managers must remain cognizant of which institutions are credible. Background checks must include attention paid to the quality of the candidate's school and
Daytime Robberies in City X City X is facing nightmares of daytime robberies that have crippled social, economic, and political stability in the city. The police officers have failed to obtain adequate information related to the causes and the perpetrators of the robberies. Therefore, coming up with a plan to investigate the cases and end the situation is important to reduce the vice. The following essay discusses some of the
