Crime Scene
Challenges: How to process the crime scene safely
Retrieving a body from the water so it can be analyzed appropriately is a considerable forensic challenge. In most crime scenes, everything is supposed to remain 'as is' until forensic personnel investigate. However, a crime scene located near a body of moving water usually means that the body must be retrieved as quickly as possible, to prevent further damage to the evidence. "Nobody is supposed to move the body (other than look for ID and some superficial moving) until the coroner's investigator gets there" (Pileggi, n.d., Crime scene). The body's removal from the water must be expedited, without disturbing any vital clues. In most terrestrial settings, "sometimes the position gives them a clue as to the cause and method of death. Also they need to see if the lividity (where the blood has settled in the body, it will always go to the lowest point and starts about 6 hours after death, and is a pinkish, purplish color) matches the position of the body" (Pileggi n.d.). But the body has already been disturbed in an aquatic setting, thanks to the movement of the water.
"Forensic handling of submerged...
The location of the body near the ravine makes it difficult for crime scene personnel to maneuver safely in the area. In any crime scene located near a body of water, both the surface (land) area and the submerged (water) area must be investigated (Ramsland 2012: 3). The body is located in water that is surrounded by rocks and other brush that make it difficult to scale. Additionally, the considerable natural matter around the body makes it challenging for personnel to create a 'clean' crime scene, and to minimize the valuable evidence from being tainted from other debris. Although specially trained divers are required to investigate the submerged area of the crime scene, under most circumstances, "investigators should look for the point of entry into the water, searching for potential evidence clothing, footprints, or indications of a struggle" (Ramsland 2012: 3). The precarious location of this crime scene makes finding such indications without danger to the on-shore…

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
Crime Scene Investigation: Homicide and Its Psychological Effects Crime scene investigation is often a challenging and difficult line of work for even the most experienced law enforcement agent. There are some crimes that are more difficult to handle spiritually and emotionally than others. Crimes against children and the elderly are often most difficult to excuse and most difficult for crime scene investigators to process psychologically (Swanson, Chamelin & Territo, 1999: 313).
This would be true although no evidence at the crime scene would connect Manson physically to the murders. The pronunciation at the crime scenes of his motive and philosophy would provide a clear line leading directly to Manson though. As the courts attempted to gain testimony against him through the young women that he'd brainwashed, the power which he levied over all of his followers became apparent. In one

The Red Dragon, with other fictional works in the same series, is a famous
Crimes and Civil Action Court cases may occur in their criminal or civil nature attracting different kinds of penalties for the offenders. In the criminal justice practice, civil action often comes in the form of a lawsuit that has been advanced to enforce, protect, or redress the rights of the plaintiffs and defendants. The focus of a civil action undertaken against a party is to protect the civil rights of the
Traditional Crime Policy Over the last several decades, the policy approach that is used in enforcing the law has been increasingly brought to the forefront. This is because there has been a sharp rise in the crime rates around the world since the end of World War II. At first, these increases were believed to be a part of the adverse changes from the war and its impact on society. (Gilling) However,
