All these features make them highly hazardous, especially to vulnerable people.4,13, Dogs incline to drag their preys down and then maul. Aside from the risk to vital organs or major blood vessels, the fast, spinning movement of the bullet may cause serious damage to the surrounding tissue it passes through. Funding was provided by Attraction and Insertion of Advanced Human Capital Program, MEC 80140078 Conicyt, Chile. Burnadean Jones. . Punctures can vary from small, requiring a bandage, to large punctures that may damage internal organs. 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. Thus, hanging was found out to be second most . 2008;10(6):301305. 1995;26(1):3741. J Forensic Sci. Forensic pathology of companion animal abuse and neglect.

The interincisal and intercanine distances can discriminate the offending dogs if there are many suspected animals involved.3,8 The incisors may not produce markings, but the presence of six incisors of an arch mark excludes a human bite. Infected people may suffer from fever and flu-like symptoms and . Domestic dogs are recognized but unappreciated scavengers;38 when an individual dies from natural (or not animal dependent) causes, he or she becomes part of the ecological cycle and the animal may simply view the body as a source of nutrition leading to postmortem depredation with obvious but grotesque changes and mutilations.20 This apparently simple assertion may not be sufficiently interpreted by the authorities, and the dog is unjustifiably destroyed (Figure 2). 4.

The participation of all forensic investigators in all procedures could strengthen the trace recovery rates thus avoiding mistaken opinions.13,17,20, It is not a minor problem to discriminate bite marks from other traumas.19 Souviron1 refers to an interesting case in which the wounds of a 7-year-old girl who was found dead and mutilated were misdiagnosed as stab wounds created by knives and/or scissors.

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. 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.

Donita uses (blank) to collect evidence from the suspect's skin for gunshot residue. The huge force the bite muscle complex can exhibit allows the dog to wrench and tear and cause considerable damage.2,4,6,8,9,12,13, Although there are reports in which many breeds of dogs have been involved in fatal or nearly fatal attacks on humans, the majority of cases involve pit bull-type dogs, Rottweilers, and German Shepherds, most of whom were unrestrained on their owners holdings.1,2,6,1315 The expression pit bull-type defines a group of breeds with special features and behavioral characteristics: a tendency to not to make intimidating gestures (growling and baring of teeth) prior to attacking, greater jaw pressures, a capacity to continue grinding their posterior teeth into tissues while holding on with the canines, and an aggressive personality in a relative larger size.

Thus, the potential for wrongly identifying a dog may result in a dog being held within kennels for long periods or a breed/type being overrepresented in incident reports.44 BSLs do not address the fact that a dog of any breed can become dangerous when bred or trained to be aggressive.14 A change in the current regulations would prevent dogs that are not dangerous but may belong to a specific breed/type from spending long periods in kennels.44 An alternative to BSL is to regulate individual dogs and owners on the basis of their behavior.14 Most of the responsibility for such attacks lies with the dog owner.7 In terms of some legislatures, a person who keeps or controls an animal in his own interest is liable without fault because he/she creates an increased risk of harm to the community.8 Generic nonbreed-specific dangerous dog laws can be enacted that place primary responsibility for a dogs behavior on the owner, regardless of the dogs breed.
