What is a bone fracture? An appropriate forensic approach must include detailed assessment of the scene, the victim, and the animals involved. Selective tissue impression, excision, and preservation and direct tissue comparison are also recommended under certain circumstances.1, Bernitz et al8 defined the pattern association of dog bite marks/tooth marks as the three-dimensional analysis and the comparison of the dental arch forms, arch relationships, and individual tooth features within the described canine dental arches.8 The bite mark is compared with dog maxillary and mandibular arch in shape, teeth position, and/or individual dental features. It was a public, painful, and slow form of execution, and used as a way to deter future crimes and humiliate the dying person. Results. They include cuts, scrapes, scratches, and punctured skin. Contact Us After an accident, quickly clear away debris, such as broken glass. 2008;10(6):301305. Hydrocolloid bandages are used to treat open, superficial wounds and open pimples. Puncture wounds are not the same as cuts. Figure 4 Experimental model designed for taking impressions of the dogs teeth by using an ad hoc recipient device (an adapted half bottle of plastic) and alginate.Notes: The procedure must be performed under general anesthesia in the case of living dogs. Cause of death. This is especially true if a bite or a rusty object caused the wound. J Forensic Sci. After that, a comparison between the bite marks of the cutaneous samples and the dental casts was made. 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). Terms & Conditions 8. What techniques were used to identify the remains? Carnivore bitemarks. Traditionally, anthropologists have evaluated SFT observed on bone and cartilage through microscope analyses by describing features of the mark and associating them with a type or an individual tool. Forensic Sci Med Pathol. 6. This work is licensed under aCreative Commons Attribution-NonCommercial-ShareAlike 4.0 International License. 2010;54(3):726745. The second, third, and fourth premolars are separated and become increasingly larger. The cause of death was attributed to exsanguination due to the extensive injuries. (b) yellow marrow. 2. Ministry of the Presidency, Government of Spain. Eight lakh cases of suicides have been reported all over the world in the year 2012 and 1,34,600 suicide cases have been reported in India in the same year amongst which 41,726 (31%) were victims of hanging. In fact, shortly after the body was discovered, the dog vomited a large quantity of commercial dog food in addition to human tissue, which indicates that the dog was not hungry at the time of mutilation. Prevention and mitigating strategies focused on both breed-specific legislation and the legal responsibility of the owner for the dog's behavior are discussed. It can be as trivial as pricking a finger with a needle or drawing pin, or as serious as the fatal penetration of the heart or lungs with a knife. In: Dorion RBJ, editor. The wounds edges revealed many small, parallel, and partially curved superficial notch marks suggestive of bite wounds. In 1992, Opeskin and Lee reported a case of a man who died from blunt throat trauma consistent with infliction by the head of a Greyhound dog.36 The key was the identification of an unprovoked and aggressive attitude toward the victim, and the resulting attack with fatal consequences. Small dogs and larger dogs can be discriminated according to the intercanine distance.8 In cases of only bone remains with deep bites, the most accurate point to measure is the mesial bone height.32 The inclusion of a metric reference in the photographs will allow metric evaluations and calibrations by using an appropriate software.3,8 Bernitz et al suggest to avoid the problem posed by the length of the canines in the match of the dogs teeth with the cast of the bite mark, by lengthening and shortening their indentations in both duplicate models of the bite to correspond them when analysis is performed. Copyright 2017 Informa PLC. During the bite, you may not feel any pain at all. To help preserve the use of your finger after an injury, its crucial to clean the wound and, For certain types of cuts, super glue is a great resource for closing and protecting the wound. 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. Number 3099067. What caused the puncture marks on the victim's bones? Fundacin Casa de la Paz [homepage on the Internet]. If a histological vital reaction is detected, it can be assumed that the victim was alive for some time in an incapacitated state prior to death and that death did not occur rapidly.34 Salem et al reported a case of an epileptic 27-year-old woman found dead in her home.3 The victim had extensive lesions on her neck produced by her mixed-breed dog. e.g. Name:_____________________________________________. Generally, bones break as a result of force and/or trauma like a car crash. 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. Borchelt et al examined most of the animals that participated in two fatal attacks and observed them under conditions simulating those that may have elicited or contributed to the maulings.5 Among the different roles analyzed by the authors, the following are remarkable: 1) the role of hunger cannot explain all patterns of dog pack attacks; 2) once the attack has been initiated, previous histories of social facilitation of feeding could have facilitated predatory behavior by the entire pack; 3) invasion of territory can lead wild and domestic canids to attack; 4) even though the majority of dogs were extremely variable in their behavior toward strangers, all the animals had unsupervised activity and aggressive social interactions with people; 5) the presence of an estrus female can lead to aggressive competition among male dogs; and 6) the visual stimulus of moving prey seems to be one of the main triggers of attack behavior. Blisters. Why was the irregular shape to the sternum of the two victims significant in the case? The investigators discovered a skin- slippage, which indicates a second victim was also melted with the first one. The December 22nd Board of Trustees meeting has been canceled due to a Winter Storm Watch declared by the National Weather Service across northern Illinois. 3.Why was the irregular shape to the sternum of the two victims significant in the case. Other mechanisms that can result in a puncture wound are infection from intravenous drug use, tattoos, multiple skin piercing and bites from animals .

He also saw fractures to the legs made around the time of death that he interpreted as evidence ofcrurifragium as well as a small scratch near the wrist that was suggestive of a nail being driven through the hand. Aurora Township provides these services and muchmore. Of course, the most interesting feature of Yehohanans skeleton is his feet. Bulk reprints for the pharmaceutical industry. 2014;10(3):401412. A compound fracture is a break or crack in your bone that is visible through your skin. Right: The calcaneus of Yehohanon ben Hagkol, with, transfixed nail. Encyclopedia of Forensic and Legal Medicine 1. Most often, a ruptured spleen is caused by blunt force trauma. Formulated with 10% benzocaine, a topical anesthetic used to help relieve pain and itch associated with bug bites and stings. 5. Stols G, Bernitz H. Reconstruction of deformed bite marks using affine transformations. Abrasions and Lacerations. [29] Select an answer and submit. 1995;26(1):3741. Puncture wounds of the foot are a relatively common problem confronting the physician. Behind them, there is a diastema followed by a small first premolar. ), Drawing of the calcaneus of Yehohanon along with a, reconstruction of the fleshed and defleshed foot skeleton. The specialist then dilutes the 100 cc to 500 cc. 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). Death by greyhound. The most common causes of cuts and puncture wounds are external injuries that break or tear the skin. 2007;173(1):7882. Note this was caused by a fist. molded impression. Both views are of the same individual. 2002;23(3):238244. Crucifixion nails were believed to have magical or medicinal properties, so they were often taken from a victim. 1. They were related to different dogs teeth and to the pattern of mauling with punctures and lacerations (canines) and tissue avulsion (incisors). The Roman orator Cicero noted that of all punishments, it is the most cruel and most terrifying, and Jewish historian Josephus called it the most wretched of deaths. So crucifixion was both a deterrent of further crimes and a humiliation of the dying person, who had to spend the last days of his life naked, in full view of any passersby, until he died of dehydration, asphyxiation, infection, or other causes. Checking out cuts, scratches, and abrasions. Why did the murderer move the body to the V.A. Death had occurred several days before the body was found. hospital where it was found by the police? When nails were involved, they were long and square (about 15cm long and 1cm thick) and were driveninto the victims wrists or forearms to fix him to the crossbar. 2010;17(4):216219. The role of histopathology in forensic practice: an overview. Even though there are problems involved in the preservation of evidence of crucifixion, the case of Yehohanan ben Hagkol showsthat skeletal evidence might some day give us more information about the practice. 7. 24 Puncture marks are usually found in thin bones such as the scapula and are caused by the canines and/or carnassial teeth penetrating through the full thickness of the bone. Forensic Sci Int. Positive concordances were made for three of the five dogs, probably the more active participants in the attack. Puncture wounds are prone to infection, and the risk of infection is even greater if the injury was caused by a dog bite. Prevention strategies should be addressed to both dog owners and people who do not own a dog by educating about how to deal with dogs, dog behavior, and dog language. 6. 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. 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. How did the scientists determine that there was a second victim? (2015, January), First aid: Cuts, scrapes, and stitches. Use tweezers that have been cleaned with alcohol to remove debris on the surface of the cut. First, attempt to stop the bleeding by covering the wound with a clean bandage and applying gentle pressure. Derwin Jordan. Without a nail in place, it becomes more difficult to tell crucifixion from animal scavengers puncture marks. If infection sets in, the complications can be life-threatening. b) Such wounds may also be caused by running over a knife, or falling upon sharp pointed objects such as broken pieces of glass. Byard RW, James RA, Gilbert JD. The abovementioned is contradictory of the current trends to prevent animal cruelty, abuse, and neglect.39 Conversely, but along the same thin line, several countries have reported an increase in the number of attacks by packs of feral dogs not only on humans but also on livestock in the last few years.16,17,40,41 Some of these countries have also attempted to enact laws to prevent this hazard. Its difficult to identify these bodies, and scavenging animals would have done further damage to the bones. Deeper cuts may require medical treatment. 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). Immediately upon excavation, Tzaferis noticed a 19cm nail that had penetrated the body of the right heel bonebefore being driven into olive wood so hard that it bent. Kane County Circuit Clerk Barreiro To Hold Expungement Clinics In September. 8. Infected people may suffer from fever and flu-like symptoms and . The incisors are used for nibbling, producing small parallel furrows on bone. Carnivora has been divided into two superfamilies, Caniformia (dog-like carnivores) and Feliformia (cat-like carnivores). Fegan-Earl A. Taphonomic changes induced by animal activity are very common, especially in outdoor contexts where the fauna is abundant. Keep the victim calm and still; movement will increase blood flow and transport the venom to the heart much faster. There are quite a few reports where the animal has been involved only indirectly in deaths. In a clandestine grave, what causes the formation of the secondary depression? Next, clean the area thoroughly using a small alcohol wipe. This much is generally agreed upon. 4. Suboccipital puncture is a procedure that was developed at the beginning of the last century. Thus, hanging was found out to be second most . When cats fight, they are usually left with at least a few cat skin wounds. If you agree to our use of cookies and the contents of our Privacy Policy please click 'accept'. Try to identify the snake; color, size, shape of head, attacking method are all useful. A cut, or laceration, is a tear or opening in the skin that occurs due to an external injury. 8. 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. Figure 1 Outdoors scavenging by dogs of a dead-by-hanging male suicide.Notes: The age of the unidentified victim was estimated to be in the 5565-year range. Although the German Shepherd has been associated frequently with fatal attacks,15,44 this breed is not considered as dangerous by some legislation,45 and it is used by both the army and the police or as a guard dog.44 This is not a minor point; police dogs are trained to bite with strength, using the entire mouth (including their whole set of teeth), resulting in more serious wounds. Why was the irregular shape to the sternum of the two victims significant in the case? 2nd ed. However, after around 3 hours, you may notice a stinging or painful sensation. Agnarsson I, Kuntner M, May-Collado LJ. Dont use heavy machinery or tools without wearing proper safety equipment and shoes. Fonseca GM, Palacios R. An unusual case of predation: dog pack or cougar attack? Keep it there for about 15 minutes. Next, clean the cut thoroughly with an alcohol wipe, antiseptic wash, or clean water. There are two types of super glue: the type you keep. Cuts or puncture wounds that are minor may be treated at home. In no particular order, find the 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. 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. 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. 2015;60(2):495500. At the scene, a pack of mixed-breed dogs of various sizes was identified later. Tsokos M, Byard RW, Pschel K. Extensive and mutilating craniofacial trauma involving defleshing and decapitation: unusual features of fatal dog attacks in the young. A ruptured spleen can be a life threatening condition and requires immediate attention. 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. Oxley JA, Farr KJ, De Luna CJ. stabbings. Curiously, it is common for dogs to have an attitude of timidity and apprehension when researchers approach and examine them.5,7,13,17, Fonseca and Palacios mentioned that while the cause of death may be readily apparent in cases of a fatal dog attack, an understanding of how and why the attack occurred requires a complete investigation and postmortem scavenging should be excluded.17 This particular pattern of behavior can occur whenever the body is accessible to animals.12 There is a preference for visible parts of the body, and self-defense injuries are absent if the victim died from other causes.13,17 The following three main consequences may be linked to scavenging: the lesions can mimic or cover antemortem injuries, make impossible the identification of the victim, and modify substantially the scene.12. Once the cut has been cleaned, apply an antibiotic cream to it. Opeskin K, Lee KA. But theres only one, single bony example of Roman crucifixion, and even that is still heavily debated by experts. 2011;206(13):e37e42. For keyboard. Puncture Wound A puncture wound is the piercing of the body by a sharp-tipped object. Read More. Several features of Spanish. Wounds caused by dog bites. Hanging is one of the commonest methods of approach in case of suicidal deaths in India. Punctures may not bleed much, but these wounds can be deep . After that, samples of the best reproduced bite marks were excised by using a rigid ring (to minimize shrinkage), collected, and fixed in 10% formalin. Pages 3951, Editor who approved publication: A puncture wound is usually narrower and deeper than a cut or scrape. Fatal dog bite in the absence of significant trauma: Capnocytophaga canimorsus infection and unexpected death. 2010;31(2):198199. Children are frequently bitten in the head and neck area because these anatomic regions are of the same height as the dogs mouth.2 In a defensive or anger bite, a dog may attempt to bite and let go showing superficial anterior tooth marks similarly to a human bite. Kiuchi T, Matoba K, Terazawa K. Unusual injuries on the right hand and forearm caused by unidentified wild animals. Nearly everyone will experience an, A cut finger can happen quickly and without warning. They are long, slightly serrated and sharp, and they are used to stab and tear and produce puncture wounds. All rights reserved. Accessed July 7, 2015. B. Accessed July 7, 2015. Odontological analysis of bite marks may provide conclusive evidence in identifying a particular animal.3,31 While in the presence of multiple animal bites, it is difficult to apply a bite mark protocol that would record every wound individually, take impressions, and remove all of the affected tissue,1 the guidelines provided by the American Board of Forensic Odontology (http://www.abfo.org) for human bite mark analysis may be useful in the implementation of the photographic protocol and in the improvement of the quality of the expertise, resulting in more strong dog identification.16 Souviron recommends taking black-and-white, color, or alternate light photographs and video documentation. Incision, puncture. Accessed July 7, 2015. If you notice debris embedded into the puncture wound, dont try to remove it. Attacks on disabled persons can be misinterpreted, leading to poor diagnoses and wrongful convictions.1,4 When lesions are fatal, they are usually located in the head and neck region causing death by means of asphyxia or hemorrhage. Skeletal bones store lipids as energy reserves in areas of 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.
