In 1992, Opeskin and Lee reported a case of a man who died from blunt throat trauma consistent with infliction by the head of a Greyhound dog.36 The key was the identification of an unprovoked and aggressive attitude toward the victim, and the resulting attack with fatal consequences. First, attempt to stop the bleeding by covering the wound with a clean bandage and applying gentle pressure. Selective tissue impression, excision, and preservation and direct tissue comparison are also recommended under certain circumstances.1, Bernitz et al8 defined the pattern association of dog bite marks/tooth marks as the three-dimensional analysis and the comparison of the dental arch forms, arch relationships, and individual tooth features within the described canine dental arches.8 The bite mark is compared with dog maxillary and mandibular arch in shape, teeth position, and/or individual dental features. 6.

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 Board of Forensic Odontology (http://www.abfo.org) for human bite mark analysis may be useful in the implementation of the photographic protocol and in the improvement of the quality of the expertise, resulting in more strong dog identification.16 Souviron recommends taking black-and-white, color, or alternate light photographs and video documentation.

Most common injury to due to shearing force; found in distal radius; victim falls forward and weight of body delivers side force, Similar to bending force but involves immobilization one segment of bone; force applied from the side; Colles fracture; cutting bone with saw for dismemberment is also shearing, Sudden stress force delivered powerfully at high speed, Stress applied slowly and builds pressure to point where bone breaks (strangulation), Force delivered in a single point or a thin line; any pointed or sharp-edged instrument (e.g. Severe damage caused by gnawing of the softer bony parts (proximal epiphyses) is frequently detected.24 Puncture marks are usually found in thin bones such as the scapula and are caused by the canines and/or carnassial teeth penetrating through the full thickness of the bone.

They are known to strip skin and tissues from the face (complicating identification) and to consume the thoracic organs making the determination of the cause of death difficult.19,29 The evaluators may have great difficulties in evaluating underlying alcoholism or significant illnesses that may have resulted in falls with bruising.26. In: Payne-James J, Byard R, Corey T, Henderson C, editors. Maybe try one of the links below or a search? Contact Us Curiously, it is common for dogs to have an attitude of timidity and apprehension when researchers approach and examine them.5,7,13,17, Fonseca and Palacios mentioned that while the cause of death may be readily apparent in cases of a fatal dog attack, an understanding of how and why the attack occurred requires a complete investigation and postmortem scavenging should be excluded.17 This particular pattern of behavior can occur whenever the body is accessible to animals.12 There is a preference for visible parts of the body, and self-defense injuries are absent if the victim died from other causes.13,17 The following three main consequences may be linked to scavenging: the lesions can mimic or cover antemortem injuries, make impossible the identification of the victim, and modify substantially the scene.12. Blunt trauma from mauling or even paw marks (when the dog tries to rouse its owner) can be misinterpreted as the result of human activity.24,26 On the other hand, perpetrators have sometimes attempted to disguise homicides by feeding the remains of victims to animals.26 Moreover, postmortem injuries from animals are usually completely incidental to the cause and manner of death.26 A fatal attack is typically repetitive, with uninhibited bites to the neck and devastating injuries to the blood vessels, the spinal cord, and to the cranium.6 Antemortem dog attacks may produce similar injuries to those arising from postmortem feeding, and a meticulous analysis of the vitality of the injuries must be performed when necessary.26, Dogs are well known for their scavenging activities; this action invariably results in serious damage to the victims body and may lead to a misdiagnosis of a brutal killing.

Exsanguination due to brachial artery laceration subsequent to multiple dog bites was indicated as the main cause of death. Bernitz H, Bernitz Z, Steenkamp G, Blumenthal R, Stols G. The individualisation of a dog bite mark: a case study highlighting the bite mark analysis, with emphasis on differences between dog and human bite marks. Carnivora has been divided into two superfamilies, Caniformia (dog-like carnivores) and Feliformia (cat-like carnivores). The distance from the tip of one upper canine to the other on a mountain lion is usually between 1.6 and 1.75, and about 1.5 between the . Short tandem repeat DNA finally exculpated the animal because the blood on its coat did not belong to the victim.31 Even though the literature recommends the euthanasia of the animal, this procedure is justified only if brain samples are taken. [29] Select an answer and submit. In a sharp force penetrating injury caused by a knife, what can be learned from the wound is directionality, force, blade width, and depth. Incision, puncture.

Keep it there for about 15 minutes. The flailing of arms, rapid movements, or attempts at self-defense by the victim can increase the intensity of the attacks (in fact, moving slowly or not moving at all can result in a reduction of this intensity).5 It has been mentioned that, in a pack situation, once an aggressive act is initiated, whether as a playful nip or a serious bite, dogs which singly taken are docile, may join and the pack instinct escalates the attack until the victim is killed or the dogs are driven off.6, We agree with Borchelt et al that the use of behavioral analysis and simulation methods to evaluate the possible factors in dog attacks can instill confidence in the observations when there is some doubt as to the cause of death in unwitnessed cases. The animals were confined for ~4 weeks and all their food had been consumed. In contrast, a cut is an open wound that produces a long tear in the skin. These causes include: The most common causes for puncture wounds include: Although puncture wounds dont normally bleed heavily, theyre prone to infection.
