Blisters. Forensic Sci Int. Bernitz et al believes that this great distortion can be adjusted only by a pattern association analysis; in fact, the physical matching of the dogs teeth to a reproduction of the bite mark can lead to this purpose as a 3D analysis. Obvious patterns, such as canine puncture traces, spaces between teeth, or abnormally positioned teeth, may allow a more reliable match with the bite mark. . Puncture wounds are prone to infection, and the risk of infection is even greater if the injury was caused by a dog bite. Lumbar puncture is a procedure that is often performed in the emergency department to obtain information about the cerebrospinal fluid (CSF). The latter is particularly the case where the person dies indoors or in an enclosed space in which the suspect animal is also confined.28.

Even though family members claimed that an alligator attacked the child, the forensic odontologist confirmed the primary diagnosis: the three family pit bulls mauled and killed her.1 Even though most fatal animal attacks are caused by large animals where the size and power of that animal simply overpower the individual,20 an exhaustive analysis of the scene, feces, hair, footprints, and claw marks is always recommended; the collection of biological samples from the wound margins can allow the confirmation of the species involved through species diagnostic markers.10,17,2123 The location of the damage along the body and the familiarity of the pathologist with different patterns of animal behavior can be of paramount importance in the correct assessment of the offending animal.19,24 At this point, outdoor and indoor interferences have specific considerations of which to be aware.12, If animal predation happens outdoors, the environmental status, meteorological conditions, local fauna, seasonal and diurnal variations, and an animals feeding and behavior patterns are important issues to be explored.19 In a case of a 65-year-old man found dead with severe and unusual injuries, Kiuchi et al identified six different species as the offending animals.22 Even though dogs are the primary scavengers in certain outdoors contexts,21 they were excluded because of the absence of specific patterns of damage.22 Studies of dog behavior suggest they scavenge remains when they are nearly fresh and soft tissue reduction can be quick (Figure 1). 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.

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). Dog bite marks usually are distorted, and the lack of quality to individualize features can lead to over interpretations of marks.8 Only when deformations are minimal, testing the match using affine transformations can be obtained by importing pictures of both suspected dogs teeth and the bite mark into the open software GeoGebra as reported by Stols and Bernitz.33 Small amounts of warping, shrinkage, and distortion will not modify the relationships of characteristics within a bite mark.33 However, the distortions in dog bite marks are usually nonuniform and beyond the resolution power of affine transformations because of the deep stabbing of the canines and the only superficial penetration originated by the incisors. Why did the murderer move the body to the V.A. In association with a veterinary doctor, all the dogs were investigated (24 Cane Corso, 1 Dalmatian, and 2 German Shepherds).

Like death by guillotine in early modern times, crucifixion was a public act, but unlike the swift action of the guillotine, crucifixion involved a long and painful literally, excruciating death. 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. If dog owners are required to assume legal liability for the behavior and actions of their pets, they may be encouraged to seek professional help in training and socializing their pets.14, Dog bite mark analysis should be consistent with a multidisciplinary plan of action involving different forensic experts as pathologists, odontologists, veterinarians, biologists, crime investigators, and others.8 The scientific inclusion/exclusion of the dog involved, regardless of the final destination of the animal, must be one of the explicit goals of the forensic approach in these cases because of the possible serious criminal, legal, and/or financial consequences for the owners of the animal.19,31 De Munnynck and Van de Voorde underlined that if dog bites are to be prevented, it is necessary to comprehend not only the particular conditions but also the behavior of both victim and dog.2 It is imperative to recognize that companion animals require to understand appropriately this relationship as a complex subject.32 Programs should strive to ensure that dogs receive proper socialization, exercise, and attention; that they are given adequate food, water, shelter, and veterinary care; that they are neutered if they are not maintained for legitimate and responsible breeding purposes; and that they are trained humanely and confined safely.14.
