Rural Road #108-19 Tempe, AZ 85284 Phone: (480) 300-477 If the gunshot wound is straight 90 degrees to the skin, the abrasion will be even all the way around the hole. If the bullet enters on an angle, the abrasion will be uneven and longer on the side in the direction where the shot was fired. Gunshot Wound Entrance. Gunshot Wound Exit. Left To Right Gunshot Wound Entrance Forensic Analysis of Stab Wounds. Estimating the length of a knife from the depth of the wound it makes can be tricky, because different parts of the body have different degrees of elasticity or give. Abdominal tissue, for instance, is soft, so that a three-inch knife plunged into the gut can be driven all the way back to the spine, producing a. Essential features Determining the range of fire is one of the most critical parts of the forensic pathologist activity; secondary effects of the discharge surrounding the entrance wound (muzzle imprint, soot deposition, stippling or blackening of the skin edges) can help estimate the firing rang There are four categories of wounds: (1) contact wounds, which can be hard, loose, angled or incomplete; (2) near contact; (3) intermediate; and (4) distant. Typical GSW wound interpretation from a pathology treatise. When the wound is a contact wound the muzzle of the gun is placed up against the body at the time of discharge. When this occurs.

Wound analysis involves meticulous examination of injuries to determine the cause of death. Many wounds carry telltale signs of their origins. Gunshot wounds leave circular entry marks on the skin and can even reveal gunpowder residue or even burn marks at close range Page 739 IMAGES IN FORENSIC PATHOLOGY Catching a Bullet: Gunshot Wound Trajectory Analysis Used to Establish Body Position Brodie Butler, Craig Fries, Joel Panock, Michelle A. Jorden, Judy Meline A knife wound can have a distinct patterns, especially if the wound is a penetrating wound or puncture. In a sharp force penetrating injury caused by a knife, what can be learned from the wound is directionality, force, blade width, and depth. Knives have a handle, and at the end of that handle is what is called the hilt Trajectory analysis of two gunshot wound pathways (only one of which was instantaneously incapacitating) was performed to assess the veracity of the officer's statement and forensic animation was used to create a court exhibit.

the overall scope of toolmark analysis. Knife wound analysis has also received little attention in forensic investigation (Symes et al. 1999). Although knife stab wounds are second only to ballistic injuries as the major cause of violent death in this country, the widespread use of meaningless and misleading descriptor Forensic Injury Analysis is often used to identify whether knife cuts are self caused. An in-depth analysis of knife wounds from a knife attack will demonstrate a pattern and identify whether a slashing motion was evident which is an infliction of long but superficial cuts or a jab which demonstrates a deep puncture wound Forensic scholars have tended to focus on evaluating wound vitality and determining the time elapsed since the wound was sustained. Recent progress in forensic techniques, particularly high-throughput analyses, has enabled evaluation of materials at the cellular and molecular levels, as well as simultaneous assessment of multiple markers

Gunshot Wounds: A Forensic Pathology Point of View

A forensic analyst uses bloodstain pattern analysis in order to tell the story of the crime. It turns out that the location where the blood lands, and the shape of the blood on the landing surface, reveal both the direction in which the blood was moving and how much force was used to wound the victim. Analysts use math principles to figure out. Incomplete or Improper Wound Analysis. As we have already mentioned forensic science and forensic medicine have moved on substantially as the years have passed. So much so that bodies can now be exhumed in order to pinpoint the exact type of weapon that was used to inflict the killer blow or shot The class introduces the wound injuries, patterns of injuries and an analysis of the forensic evidence. The collection and identification of this evidence is covered in the class along with unique case histories that will re- enforce the experienced investigator on what is needed to improve on the investigation and what may be missed in making.

Going by the gait. Gait analysis for forensic purposes is defined as the analysis, comparison, and evaluation of human gait including the components and features of gait, to assist the process of identification or to answer any other legal question concerning gait, according to Forensic Podiatry. 2 Gait analysis works with what we call 'class characteristics. A total of 117 vital skin wounds (post infliction intervals between a few seconds and 7 months), 20 postmortem wounds and skin specimens with beginning or advanced signs of putrefaction were investigated. Different markers for macrophage maturation (27 E 10, RM 3/1, 25 F 9, G 16/1) were analyzed by immunohistochemistry. The early stage inflammation marker 27 E 10 stained macrophages, but also. For the forensic pathologist, it is usually easier to rule out or eliminate a particular knife as having characteristics incompatible with the wound, such as a serrated edge. To identify a particular knife as the weapon used to inflict the wound, law enforcement must collect other evidence from the weapon, such as the victim's blood or DNA This forensic analysis (FA) only analyses the two felons injuries and the firefight that produced these wounds.

Odontological analysis of bite marks may provide conclusive evidence in identifying a particular animal. 3,31 While in the presence of multiple animal bites, it is difficult to apply a bite mark protocol that would record every wound individually, take impressions, and remove all of the affected tissue, 1 the guidelines provided by the American. The forensic science, has grown a multifaceted structure to help the Courts. And the good thing is that it has not stopped. It is still growing and developing new areas where it can assist the Courts. Presently, the main areas of help where the forensics do assist a Court are given here: 1.

In the early 1800s, forensic medicine was not divided into distinct disciplines. Physicians and surgeons who performed autopsies and testified in court depended on a variety of sources for their income and provided expertise as needed. No regular system of payment was provided for expert testimony, laboratory analysis, or postmortem examination Analysing and evaluating the projectile wounds (living target), impact of projectile (inanimate objects) and fate of the projectile after hitting the target. The identification of the weapon of offence and linking it to the scene of crime as well as the offender/suspect is the primary aim of a forensic ballistic expert and this is carried out.

Forensic medicine thus involves the collection and analysis of medical samples to deduce facts admissible in the court of law. For instance, identification of wound patterns can help determine the weapon used to inflict the wound He was later exonerated by DNA. Similarly, Roy Brown was convicted of murder due in part to bite-mark evidence, and freed after DNA testing of the saliva left in the bite wounds matched someone else. The very basic technique and analysis employed by most forensic odontologists is as follows: Bite marks are photographed with a scal The analysis of the shapes, patterns and locations of blood stains has become a field of specialization in forensic science to piece together how events unfolded during a shooting, stabbing or beating. Depending on the type of injury inflicted, blood can spurt, drip, gush, ooze, spray or flow as they leave the body

In an effort to determine precisely how and when a specific crime took place, forensic investigators have studied gun shot wounds in great detail. The examination of gunshot wounds has often been the deciding factor in the prosecution or exoneration of the accused. We have provided photographs of gunshot wounds to illustrate what we are describing In a forensic investigation, analysis of GSR revealed a wide range of issue from the identification of shooter to relating a bullet with a wound. It also helps in reconstructing a crime involving a firearm. [11 3. A trajectory analysis of JFK's inshoot/outshoot head. trajectory conclusions.

What is Blood Spatter Analysis? Blood Spatter Analysis or Blood Pattern Analysis (BPA) is the examination of bloodstain shapes, locations, and distribution patterns, to provide an interpretation of the physical events that gave rise to their origin. In forensic investigations, it is ubiquitous to encounter blood on the crime scene Stabbing wounds are also probed for any evidence of the weapon and the pattern of the wound in the skin. Photography at all stages in the investigation is a critical part of the forensic autopsy. *The interpretation of the head wounds used in defining trajectory reported in testimony on Sept. 12, 1978 differs from this report because the final illustration from the Forensic Pathology Panel showed the exit wound to be 1 centimeter lower than the entrance, rather than level with it as had been concluded earlier
