Bloodstain pattern analysis (BPA) is one of many specialties in the field of forensic science; the science of bloodstain pattern analysis use scientific knowledge from other fields to solve problems. BPA also uses the scientific method to examine bloodstain evidence at a crime scene where blood is present by gathering information, observing, documenting, analyzing, evaluating, and technical or peer reviewing. A bloodstain pattern analysis job is to collect, categorize and interpret the shape and distribution of bloodstains within a crime scene (Peschel, 2011). Bloodstain patterns can reconstruct a crime scene and then determine the crime as an accident, homicide, or suicide; the blood can also identify the location, quality and intensity of an external force. The purpose of a BPA’s is to determine bloodstain patterns and to recreate the action that caused the blood.
In the span of 7 weeks, there has been 7 cases of violent homicides at various locations Tenderloin, Oakland. Each homicide was reported by local garbage officials, who discovered the bodies while they were working. The victims vary in age, but all 7 are black males with braided hair. 6 of the bodies were found next to a dumpster, with the single exception inside one. All victims were bludgeoned beyond recognition and missing different body parts (each victim was mutilated, with the missing body part nowhere to be found). Judging from the bruises in the victims legs, the coroner infers the victims were bludgeoned with a baseball bat to death and mutilated with an axe post-mortem. The coroner determined victims time of death on Sunday evenings, with a single exception (the one found inside the dumpster) to be Tuesday morning. Police are having a hard time finding evidence, as there were no foreign prints nor DNA on the bodies of the victims.
T. Paulette Sutton is one of the world’s leading experts in bloodstains and is the former Assistant Director of Forensic Services and Director of Investigations at the University of Tennessee, Memphis. She has been involved in nationally known murder cases and has worked hard during her long career to make a position contribution to the legal system. Sutton says, “Its best for my fellow man that we get the killers off the street.” Since 2006 Sutton has been officially retired but continues to teach, consult, and testify about her area of expertise.
A body was found with no identification was found on the body. An external examination of the body found numerous needle marks and bruising and thrombosed veins in the cubital fossae. The head showed evidence of a blunt trauma and small paint and metal fragments were removed from the wound. Analysis of the contents in the stomach found a few partially digested potato chips and some partially digested pills. A small amount of residue was extracted from the tin for analysis. Footprints were evident on the carpet where soil had been tracked in. Soil samples were collected from theses footprints. This analysis will show how Infra-red spectroscopy and Chromatography would be useful in finding both the cause of murder and possibly who the culprit was.
During a forensic investigation the scientist may compare a suspect’s knife with the holes on the victims clothing can provide clues and details of the offending knife. In carrying out either of the investigating, it is necessary to know if the dimensions of the knife blade are accurately reflected in the resultant stab-cut seen in the clothing.
2. If a violent murder occurred as the result of the killer wielding a weapon over his or her head or from side to side would result in a line of blood spots on the ceiling or wall, similar patterns on walls could be the result of the victim being flung across the room. If the victim crawled
There was additional blood on the console, door, steering wheel and carpeting. Once again, there was a DNA test that found traces of blood containing ties to Goldman, Mrs. Simpson and Simpson. The defence challenged the DNA interpretation; arguing that the somewhat “unknown” traces of blood belonged to the police who allegedly framed Simpson. Still, the defence lacks valid motive for the police to do this. The prosecution said that Simpson drove the Bronco to and from the crime scene. This would accurately explain the blood found in the
Sudbury is a known place for 2 local gangs that have been fighting over the land for years now. Police investigating has concluded that the cause of death a major loss of blood. The coroner told police that he would have survived his injury if he had gotten to the hospital in time. He also added a brief profile of the killer; left-handed, caucasian, brown hair, and male. The blade in question is still missing following a police investigation.
Abstract: I am a detective in a town that has elected their sheriff the coroner. It is September and local time is 2pm. A moment ago I received a call regarding a body that was found in a countryside area known for small game, namely squirrel, hunting. I am going to investigate the body and detail the methods I will use to identify the body, the signs I am looking for to tell me the length of time since death has occurred, and list the indications for determining the injuries to the body in relation to the manner of death in this paper.
