Its not likely that a lot of evidence will be found, though, for a number of reasons: In the first century BC, during the revolt of Spartacus, there were reports of over 6,000 crosses with crucified victims on the road from Capua to Rome, and in the first century AD, the Romano-Jewish scholar Josephus reported that up to 500 Jews were crucified every day during the siege of Jerusalem. e.g. Fatal dog bite in the absence of significant trauma: Capnocytophaga canimorsus infection and unexpected death.

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. 2013;58(1):224227.

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.

These observations can provide some insight into the warning signs of dog attacks.5, Strategies for prevention and risk mitigation, Severe dog attacks are a probable product of many factors not only animal related but also victim related.2,5,14 A public health program that aimed at reducing these incidents could be directed to both of them, but the major strategy has been the promotion of a breed-specific legislation (BSL).1,13,44,45 BSL typically prohibits the breeding and ownership of certain breeds or types of dogs categorized as dangerous or aggressive, which is based on attack records or aggressive potential.46 However, any dog can be prepared for attack and a precise determination of breed may not be posible.8,13 Obtaining a honest attack record is difficult due to scarce data on the reference population, incomplete breed registration, incorrect breed identification, the number of nonpurebred dogs, and the narrow scope of relevant studies.6,14,46 Moreover, while BSL is rarely based on such records,46 periodically there are reports of other breeds responsible for maulings and deaths.4 Saint Bernard, Great Dane, Golden Retriever, Collie, Labrador Retriever, Dachshund, and Yorkshire Terrier are not aggressive breeds, but they have mauled persons to death on occasion.14 Great Danes caused the most reported human dog bite-related fatalities between 1997 and 1998 in the United States, and since 1975, dogs belonging to >30 breeds have been responsible for fatal attacks on people.14 Cornelissen and Hopster affirmed that all dogs can bite and therefore one should always be careful when interacting with a dog, even a family dog and during play.

The evidence was not preserved, the appropriate experts were not asked for a timely evaluation, and finally, the prosecutors office and experts were sued for malicious prosecution, false imprisonment, and gross negligence.1, The domestic dog accounts for the majority of deaths caused by animal attacks, but a variety of animals can leave similar patterns of damage. Another part of the equation is what caused the puncture wound. Once the spinal cord is severed, all body function ceases. Taphonomic changes induced by animal activity are very common, especially in outdoor contexts where the fauna is abundant. 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. J Forensic Sci. What caused the rapid decompositions of the bodies. A ruptured spleen can be a life threatening condition and requires immediate attention. A bullet lodged in the brain can never be seen in radiographs (X-rays). 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. Surfaces that are no longer continuous and no longer meet or meet at an unnatural angle.

As a result, the dogs incisors can be matched to the indentations on the plaster cast, representing a dynamic pattern of biting.8, Santoro et al16 reported a case of a 45-year-old man found dead on the ground of an abandoned military base with signs that he had been dragged. Finally, the trunk is disarticulated and consumed.19,21 Coyotes, wolves, and domestic dogs are known to disarticulate body parts and scatter them over a wide area.21,25. Energy is lost and the fracture line stops; helps to determine sequence of breaks in bones when there is multiple fractures, Breaks that occur in bones that are weakened by disease, intermittent stress over long periods of time (dowagers hump), Blood clotting in damaged area stablizes the broken bone pieces; stimulates osteogenic layer to produce connective fibers to span broken surfaces, New veins and connective tissue will form; sharp broken bone will round due to resorption; fibrous bones forms; then woven bone forms and replaces fibrous bone; callus forms, Visible raised, irregular area; forms 6 weeks after injury; can be visible for years or be resorbed leaving no indication, 1) Tension; 2) Compression; 3) Torsion; 4) Shearing; and 5) Bending, Force pulls on bone; common in dislocations; usually along long axis, Force pushes down on bone; commonly found in skull; complete or incomplete fracture; numerous and wide reaching fracture lines; shape of weapon leaves mark on bone, Twisting; spiral fracture; one end of bone held stationary while other end is twisted; common in long bones; skiing accidents and child abuse, Force impacts bone at right angle to long axis of bone; discontinuity common but few fracture lines; may cause butterfly fracture; adults complete fracture common; subadults incomplete fractures (greenstick). 1995;26(1):3741.
