The majority of bite marks were photographed and excised. 5k views Reviewed >2 years ago. The abovementioned typical hole-and-a-tear is a puncture wound (the round hole) produced by the canine tooth of either the maxilla or mandible on one side, which serves as an anchorage point, followed by shaking of the head creating tears enhanced by the cadavers body weight. car accidents. The force of impact is concentrated at the tip of the implement, and the sharper the tip, the easier . Puncture wounds of the foot are a relatively common problem confronting the physician. These patterns allow the discrimination with bites of other species, which are not accompanied by shaking nor by the usage of canines, and with stab wounds caused by sharp weapons.2,4,8,13 Animal hair is occasionally found inside the wound.30 In cases with numerous wounds to the face, it has been recommended to take a cranial X-ray to check for bone fractures and the presence of foreign bodies.23, Canids leave typical postmortem damage patterns on the bones, characterized by rounded punctures, peg-like penetrating injuries, and shallow scratches. A puncture wound is caused by an object piercing the skin, creating a small hole. Dogs, cats, and kin: a molecular species-level phylogeny of carnivora. They are small and run quickly mimicking small prey, and they are usually unable to escape from a mauling dog. Spanish. How did the scientists determine that there was a second victim? The intended goal of striking this area with a knife is to sever the spinal cord/brain stem. Although the German Shepherd has been associated frequently with fatal attacks,15,44 this breed is not considered as dangerous by some legislation,45 and it is used by both the army and the police or as a guard dog.44 This is not a minor point; police dogs are trained to bite with strength, using the entire mouth (including their whole set of teeth), resulting in more serious wounds. Furthermore, the sequence of consumption and disarticulation of human bodies is relatively constant and recognized: feeding usually begins at the face and neck and then moves to the thorax. 1. 7. Change the bandage daily and whenever it becomes wet or dirty. We avoid using tertiary references. Neck wounds are usually slanted perpendicularly to the neck and positioned in an anteroposterior direction. An infected cat bite wound will be red, swollen, and painful, and the infection can spread through the surrounding tissues, causing a condition called cellulitis, or through the blood to other areas of the body, causing a condition called septicemia (often called blood poisoning). Derwin Jordan. 6. The son of the victim indicated that the three responsible dogs were his own, and he was condemned for manslaughter.6, Is important to note that the odontologist does not usually visit the crime scene or even the mortuary, and he or she must work only from photographs or the autopsy report.1,17 A photograph is a static representation of a dynamic action, and it is not the way an animal bite looks like in reality. Wear shoes and make sure the soles are sturdy and cannot be punctured by a nail. 2015;60(Suppl 1):S11S20. A study by Fitzgerald and Cowan noted 887 patients with puncture wounds from a total of 108,648 emergency room visits by children.Reinherz et al attributed 7.4% of all lower extremity trauma that presented to the emergency room over a 12-month period to puncture wounds. Am J Forensic Med Pathol. Cooperativa.cl. 2011;206(13):e37e42. The injuries were photographed, and the distances between pairs of punctures were measured. A small number (1.8%) of these puncture wounds become infected and progress to osteomyelitis. 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 . Fundacin Casa de la Paz [homepage on the Internet]. The bite mark pattern is considerably different from those on the limbs, the neck, and the cranium. 1992;56(1):5157. Factors that prompt the person to 1) stop breathing and 2) the heart to stop beating. This may result in the consumption of gunshot wounds (with or without projectiles) and stab wounds, making postmortem assessment of lethal wounds difficult.10,23,26,34 To make the picture even more complex, in certain fatal dog attacks, injuries may be sustained that resemble postmortem depredation: decapitation and defleshing of the face and head of children by animals occurring during life are often witnessed and are usually associated with significant hemorrhage.4,34 Although postmortem injuries caused by animals do not show a vital reaction and tend to have yellow-reddened, dried limits, trauma to congested dependent areas may show considerable hemorrhage from postmortem oozing.10, We concur with the literature in that histopathological diagnoses serve to reconstruct the event and provide additional information helpful in the overall evaluation in such cases.16,23,35 Koszyca et al34 demonstrated the value of taking tissues damaged by animal bites during autopsy for histological assessment, as this may be a crucial step in determining the timing of the injuries, and in helping to elucidate the chronology of the fatal event. Note this was caused by a fist. 2nd ed. 7. An appropriate forensic approach should include an exhaustive analysis of the scene, the victim, and the dog.

Although a Pit Bull Terrier was found at the time of death in the victims house, and there was physical evidence of its involvement in the death, the mother spent almost 4 years awaiting trial for an inexistent murder, suffered over the death of her daughter, and lost custody of the other children. Due to the protests of these groups and to the controversy generated in the public opinion, the rule was finally abolished 15 days later.43, Regardless of any subjective appreciation, hunger is reasonably the first motivation explained when dealing with dog scavenging; however, this hypothesis cannot explain the mutilation patterns where the postmortem interval was too short for starvation, dogs had access to food, or the injury pattern cannot be explained as an initial feeding behavior.12,30 Rothschild and Schneider (1997)30 present a case in which a well-behaved pet dog (an Alsatian) with no motivation of hunger started to mutilate the body of its owner within the first 45 minutes after death. a rash with bumps, red spots with a "halo," and swelling around the bite . In some cases, puncture wounds can be excised.8, A forensic approach to a suspected fatal dog attack should include not only the detailed exploration of the victim and the dog but also the appropriate assessment of the scene. Gunn A. If you see debris embedded in the cut, dont attempt to remove it. For the most part, crucifixion involved soft tissue injuries that cant be seen on bone. 2012;126(3):441446.

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. In a predatory bite, a dog can clamp a large portion of tissue using posterior teeth and cause drag marks and lacerations by shaking and pulling. A careful look for potential footprints in bloodstains will allow for the detection of evidence of pets living free in the house or wild animals having possible access to the scene.12,13 Although domestic dogs do not feed on a corpse usually, they could be motivated by hunger to consume cadavers if they have no food available.12 Steadman and Worne reported in 2007 an interesting case in which a 54-year-old woman, who lived alone in her residence, was nearly completely consumed by her two domestic dogs (a Chow and a Labrador mix). Obvious patterns, such as canine puncture traces, spaces between teeth, or abnormally positioned teeth, may allow a more reliable match with the bite mark.

Death was attributed to exsanguination due to the neck blood vessels laceration subsequent to the dog bite. Ministry of Agriculture. Eight lakh cases of suicides have been reported all over the world in the year 2012 and 1,34,600 suicide cases have been reported in India in the same year amongst which 41,726 (31%) were victims of hanging. No radiating fracture lines; long bones break at right angles with flat ends; color of break different from rest of bone; David Halliday, Jearl Walker, Robert Resnick, Mathematical Methods in the Physical Sciences, Physics for Scientists and Engineers with Modern Physics. A scientific inclusion/exclusion of the dog involved is possible and also recommended because of the possible serious criminal, legal, and/or financial consequences for the owner of the animal. Treatment options for deep cuts include stitches, staples, or liquid stitches. Deeper cuts may require medical treatment. 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. In contrast, a cut is an open wound that produces a long tear in the skin. Fatal dog attacks have been sporadically reported, and deaths usually result from unwitnessed attacks.13 Animal interferences can happen before and/or after the death of the victim, creating artifacts and difficulties in diagnosis during the forensic examination.19 Since introducing the dog bite mark evidence in court will require the skills of different experts in the forensic sciences,8 the different steps and procedures proposed in the literature are reviewed.
