Injury caused to living tissue by an outside force, Bludgeons, projectiles, cutting, chopping, hard surface, chemical, extreme heat (fire), extreme cold, Medicolegal aspects for death investigation, 1) Trauma that occurred at time of death, before death or postmortem 2) Force that caused trauma; 3) Number of wounds; 4) Sequence of wounds, if multiple wounds; 5) Placement of wounds, Factors that prompt the person to 1) stop breathing and 2) the heart to stop beating. What caused the puncture marks on the victim's bones? A/an _________ is longer than it is deep while a/an _________ is deeper than it is long. Common items that cause puncture wounds are nails, knives, bones and wood. 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. 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. Sacks JJ, Sinclair L, Gilchrist J, Golab GC, Lockwood R. Breeds of dogs involved in fatal human attacks in the United States between 1979 and 1998. [29] Select an answer and submit. A puncture wound is caused by an object piercing the skin, creating a small hole. 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. Sometimes in the hand, sometimes in the nose cavity, or the foot, these minute metallic objects are of unknown substance and would appear to be some kind of tracking device. 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. 2007;28(2):177181. Note this was caused by a fist. Bones - Episode 4, Season 3 "The Secret in the Soil". Consequently, the surrounding bloodstains would be distinct from the spatter emanating from a living person.28 A common situation of dog scavenging in indoor interferences is presented in Diogenes syndrome. Forensic Sci Med Pathol. Sometimes, a bullet can cause a puncture wound . Several drag marks and an oblong perforation are also present on the left side of the frontal squama, as well as scraping drag marks close to bregma. Without a nail in place, it becomes more difficult to tell crucifixion from animal scavengers puncture marks. All human biological evidence, including a mass of gray human head hair, a calvarium, and small fragments of long bones, were found in the main walkway of the living room between the bedroom and bathroom, and a considerable amount of animal feces covered the floors. If infection sets in, the complications can be life-threatening. The jaws of the three suspected dogs could be clearly matched to the bite marks. What caused the rapid decompositions of the bodies. 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. Learn how we can help. Crucifixion seems to have originated in Persia, but the Romans created the practice as we think of it today, employing either a crux immissa(similar to the Christian cross) or a crux commissa (a T-shaped cross) made up of an upright postand a crossbar.

The claw marks on the skin of the victim will be reflection both length and sharpness of the dog claws, and they will be affected by the surfaces walked by the dog, its size, and its breed.8. Then, lift the injured area up to the level of the person's heart. A doctor should always examine a deep puncture wound. They can cause other dangerous medical conditions like rabies, blood . Clean the wound. The fourth maxillary premolars and the first molar are referred usually as carnassials, and they are extremely sharp. This can prevent infection and speed the healing process. Am J Forensic Med Pathol. Intercanine and interincisal extents on each cast were registered by using a digital caliper. 1. This meant they were rarely left in the victim's heel and the holes they left might be mistaken for puncture marks. 5. 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). Ministry of the Presidency, Government of Spain. Bitemark Evidence: A Color Atlas and Text. Haglund WD, Reay DT, Swindler DR. Canid scavenging/disarticulation sequence of human remains in the Pacific Northwest. The cause of death was attributed to internal hemorrhage as a consequence of multiple fractures and external hemorrhage. For example, if a soldier frequently marches with a heavy pack on their back, the repeated force on their leg could . If they hit a bone, they can either break or shatter it, or be deflected in another direction. 2. Treatment options for deep cuts include stitches, staples, or liquid stitches. 1995;26(1):3741. Dorion RBJ. 4. Most of the dogs involved in these events are known to the victim or belong to him.28 A bite mark is defined as a physical alteration in a medium caused by the contact of teeth.9 When a bite mark is caused by an animal, the following three patterns can be observed: nonfatal bite wounds, fatal bite wounds, and postmortem lacerations of the victims body.2 This poses the major points and challenges of forensic interest; the nature and location of injuries and the final cause of death are not the only topics of attention.2,6,9 A careful assessment of wounds can reveal characteristic features of animal activity with typical patterns that may enable identification of the particular species of animal involved.10 Since dog attacks on humans represent a real health problem with obvious challenges for forensic investigation, a review focused on bite mark analysis from a multidisciplinary point of view is presented, and the current strategies for prevention and mitigation are discussed. Apply cold packs and elevate the area to reduce pain and inflammation. 1992;56(1):5157. Where researchers disagree pretty significantly is in the method of crucifixion of Yehohanan. Bone fractures are classified by their pattern, cause and where they happen in your body. If there are not enough thyroid hormones available in the body, the anterior pituitary can release thyroid-stimulating. They create and support wound healing. ), Crosses at sunset. Gunn A. 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. The bioarchaeology of crucifixion is therefore a bit of a conundrum: it makes sense that finding evidence may be difficult because of the ravages of time on bones and wooden crosses, but the sheer volume of people killed in this way over centuries should have given us more direct evidence of the practice. They exhibited overall good health.25, Death from dog attacks may be caused directly or indirectly by blunt and sharp trauma, crushing, envenomation, anaphylaxis, or sepsis.26,27 This wide variety of mechanisms can lead to problems of diagnosis if the forensic pathologist is not aware of all the details of the case. ice pick, knives, axes, meat cleavers), Force delivered over a wide area; caused by anything other than a cutting or chopping instrument, 1) Blunt; 2) Sharp; 3) Projectile; and 4) Miscellaneous, Injury caused by that has a wide area of impact on bone, Compression, Bending; Shearing (occasionally), Discontinuity and fracture lines; simple and comminuted fractures; caused by any hard surfact, Usually caused by cutting and chopping instruments; Dismemberment and animal scavenging; When force applied perpendicular and down - puncture wounds; usually infractions, Complete discontinuities with displacement and fracture lines; bullets, arrows, and spears, Dynamic speed of force for projectile trauma, Anything that is not blunt, sharp, or projectile; strangulations, burns, chemicals, explosions, heat, 1) Antemortem; 2) Perimortem; 3) Postmortem, Trauma already starting to heal; porosity; rounding of edges; presence of callus, Will not exhibit signs of healing; can have green bone response, 1) Sharp edges; 2) Hinging; 3) Formation of fracture lines; 4 ) Broken ends with angled jagged surface 5) staining from hematoma, Between time of death and discovery of body. If the fastening is lost, a dog tries to thrust its head forward to seize more tissue, thus creating double or superimposed bites.9, Children are especially defenseless to mauls from domestic dogs for different motives.
