Murmann et al underlined that animal bites, especially that of dogs and carnivorous wildlife, can produce multiple deep, streaked lacerations requiring a considerable force, and resulting in the loss of tissue or avulsions.32 Conventional techniques to analyze and/or match these patterns (acetate sheeting for example) can be used but the resulting visual model will not represent the real dynamic of the bite mark.8 It has been emphasized that quality and quantity of the material must be sufficient and convincing to defend a positive match.

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).

Diagnostic problems associated with cadaveric trauma from animal activity. If they hit a bone, they can either break or shatter it, or be deflected in another direction. Seek help from your doctor or go to the nearest emergency room.

Where researchers disagree pretty significantly is in the method of crucifixion of Yehohanan. 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. However, the real circumstances were quite different as the attacking dog (in fact, never confirmed as a pit bull) actually attacked the victims pet (an Irish Setter), and the owner suffered a sudden cardiac death while trying to separate them. Death was attributed to exsanguination due to the neck blood vessels laceration subsequent to the dog bite. The parallel cutaneous lacerations on the margins of damaged skin and the presence of feces in the vicinity of the deceaseds head are distinctive of rodent activity. Boca Raton: CRC Press; 2011:217240. 2012;126(3):441446. The cause of death was attributed to exsanguination due to the extensive injuries.

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). 2007;28(2):131136. Forensic Sci Int. Also a forensic biologist can provide additional data on sources of attacks or scavenging that can be used to evaluate such incidents.1,6,8,13 In a case reported by Fonseca and Palacios, a forensic odontologist and a carnivore biologist revealed that the injuries in a fatal attack were consistent with a pack dog attack (Figure 5).
