The search of the crime scene is the most important phase of any investigation. Decisions of the courts restricting admissibility of testimonial evidence have significantly increased the value of physical evidence in homicide investigations. Therefore, law enforcement personnel involved in the crime scene search must arrange for the proper and effective collection of evidence at the scene.The arguments the lawyer’s will make in the William’s case is: once an item is recognized as evidence it must be properly collected and preserved for laboratory examination. However, in order for physical evidence to be admissible, it must have been legally obtained. The courts have severely restricted the right of the police to search certain homicide crime scenes without a search warrant, (Mincey v. Arizona 437 US 385, 1978).…
Recently, an interesting case of murder involving a young married woman was unravelled by the crime scene team. The collection of evidence and laboratory examination of exhibits provided the corroborative evidence necessary to prove the victim’s in-laws were trying to mislead the Investigating Officer by fabricating a story of looting and murder…

The forensic aspect of the Pamela Foddrill case made the differences between the theory and the reality of criminal investigation very apparent. When Foddrill’s body was found in December of 1995, the cause of death was originally ruled as violent trauma, indicated by the “broken and splintered nasal bones and fractures to her neck” (Course 69). A few years later, forensic pathologist Scott Wagner said that Foddrill’s injuries, while harmful, were probably not fatal, and the cause of death was changed to blunt force…

New technologically advanced 3D computer reconstructions allow the viewer to see real images of the crime scene much like watching a television show. The virtual world can be created using 3D lasers and computer software. The crime scene is taking on a completely different view. No longer is the crime scene restricted to inside of the crime tape. It has moved beyond a physical barrier allowing analysts to dissect the crime scene to identify evidence often missed simply walking through the traditional steps of sketching. There is now the opportunity for anyone to revisit the crime scene the next day, next week, or years from now. This is an important function to allow the jury to see exactly what the investigators and witnesses saw at the crime scene leaving nothing to the juror’s imagination.…
According to the Academy, different forensic methods are filled with assumptions because the lack of scrutiny has denied the methods chances to prove that the methods are not scientifically correct and accurate hence no change to improve them to perfection. As a result, similar errors continue being repeated over and over again (Turvey, 2012). For example, in a different case where a child was murder and dumped near a river, a man who was a bar attendant was accused of having been the perpetrator. According to the forensic team, a bite mark proved that the waiter (Brook) was the person who had bitten the child to death a thing that led to Brook's life incarceration (http://www.pbs.org/wgbh/frontline/film/real-csi/). Only years later when Brook was in prison that a similar case happened, again and again, another innocent person who was the child's stepfather was determined by Bite Marks test to be the perpetrator a thing that scientists and experts consider as invalid science. Such forensic methods are considered invalid due to lack of eye witnesses, valid objects that can be used or any other tangible evidence. Unfortunately, intangible evidence like the conduct of a person or any awful smell that the expert would assume is a scent of a particular crime hence automatically concluded that the individual was involved and upon making…
The search for physical evidence at a crime scene must be done thoroughly and followed by the protocol. How the criminalist will decide to execute the crime-scene investigation depends on the size and the locale of the area, as well as on the actions of the suspect(s) and victim(s) at the scene. It must be considered that physical evidence can be anything, from a massive object to a microscopic trace, however, some evidence are clearly visible but others need to be examined in the laboratory in order to be detected. Physical evidence must be processed in a way so as to prevent any change from happening between the time that was collected on the crime scene and the time it is received by the laboratory. When collecting physical evidence from a scene, any criminalist must be aware of the fact that recovery of one type of evidence can destroy another.…
Homicide is the killing of one human being by another. (Osterburg, J. 2014). Robbery is the act of robbing a person or place. (Osterburg, J. 2014). The crime scene assessment provides the major opportunity to locate physical evidence. The initial response should be regarded as the only chance to recognize, record, and collect physical evidence. The investigator must make the most of it. This search, however, must be conducted properly and lawfully, or the evidence will be suppressed in the course of a trial. Police should not relinquish control over the scene and its environs until all evidence has been discovered, documented and collected. If it must be gone over again later, legal difficulties may be created because…
Merits: The respondent, Daniel Murphy, was convicted by a jury in an Oregon court of the second-degree murder of his wife. The victim died by strangulation in her home in the city of Portland, and abrasions and lacerations were found on her throat. There was no sign of a break-in or robbery. Word of the murder was sent to the estranged husband, Daniel Murphy. Upon receiving the message, Murphy promptly telephoned the Portland police and voluntarily came into Portland for questioning. Shortly after the respondent’s arrival at the station house, where he was met by retained counsel, the police noticed a dark spot on the respondent’s finger. Suspecting that the spot might be dried blood and knowing that evidence of strangulation is often found under the assailant’s fingernails, the police asked Murphy if they could take a sample of scrapings from his fingernails. He refused. Under protest and without a warrant, the police proceeded to take the samples. After this evidence was collected, Murphy was released and was not formally “arrested” until approximately one month later. The samples turned out to contain traces of skin and blood cells, and fabric from the victim’s nightgown. This incriminating evidence was admitted at the trial over defense objections.…
