Fatal neck injuries caused by blank cartridges.

We report three cases where fatal neck injuries were caused by blanks from starting pistols. The weapons were loaded with blank cartridges or tear gas cartridges. Neither live ammunition nor any form of projectile was used. All three cases involved a contact discharge. The gas pressure caused by firing the weapons created extensive wound cavities in all three cases. Each victim died from blood loss as a result of ruptured cervical vessels; there were no air embolisms. In one case, a man shot himself eight times with two different starting pistols, and the wounds could be matched to each gun by the muzzle imprint marks on the neck.     

Investigation of the variability in the tool marks produced by modified blank firing pistols on fired 7.65 mm projectiles

Firearms identification has an important place in forensic ballistic investigations since the weapons are widely used in criminal offences. Firearm examiners resolve many case files, through the use of automatic systems or comparison microscopes. Advanced forensic technologies like BALİSTİKA helps to record and analyze non standard ballistic evidence. In today's world, with the ease of access to materials and production technique information, pistols modified from blank firers are frequently encountered as crime tools. In this study, the characteristics of 7.65 mm fired cartridge cases obtained by controlled shots from blank firing modified pistols were examined, and their detection performances were compared by means of the Balistika system. Although distinctive differences are not expected after successive test shootings, balistically important changes were seen after the use of blank firing modified pistols and the 3D imaging system proved to be useful in observing such differences. The analyses showed that the modifications in weapons lead to variation in the ballistic characteristics and reduce the accuracy of the detection performance, which may result in flawed forensic decisions. It was also found that the deviations in ballistic impressions of modified blank firing pistols were greater than that of standard fabricated and hand-made pistols. This unique study contributed to the forensic sciences literature by focusing on the impact of modified weapons on ballistic characteristics.     

Modification Methods of Blank Pistols in Turkey in 2006

Abstract:  This study describes the modification methods of blank cartridge firing pistols in Turkey. We have examined cases submitted to the Aydın Regional Criminal Laboratory of Turkey in 2006. In total, 95 modified pistols and 300 modified cartridges were examined. The blank cartridge firing pistols are guns which look similar to "real" pistols, however, there are blockages in their barrel in order to prevent the discharge of a bullet. However, as a result of simple modifications, these pistols can be easily converted into "real" firearms. Studied modification methods are removing the obstruction from the barrel, removing the partial obstruction from the barrel, sleeving a smaller diameter tube into the original barrel, using a replacement barrel, and rifling the original barrel. Special cartridges for these modified pistols are also produced. These modified pistols and cartridges were evaluated in respect of the converting methods.     

Injury potential of soft-air pistols

Report on a case in which an 8-year-old girl was injured on the left anterior thoracic wall by two shots fired by her 14-year-old cousin from a soft-air pistol (replica of mod. 17 make Glock, cal. 6 mm, solid plastic bullets); the projectiles caused two skin lesions, both reaching into the subcutis. The results of our own shooting tests with 2 different soft-air pistols and the injuries seen in our case confirm that soft-air pistols may cause penetrating soft-tissue injuries when fired from a short distance.     

Is the exploding powder gas of the propellant from blank cartridges sterile?

Shots from blank weapons loaded with blank cartridges, when fired from close range or as a contact shot, almost always cause the skin to burst open and lead to injuries to structures below the surface. Subsequently, wound infections are often observed. In addition to the introduction of skin germs, the possibility exists that contaminated propellants may enter into consideration as a source of infection. Using step-by-step experimental procedures we were able to demonstrate that: 1. Blank cartridge propellants were almost always contaminated with Bacillus cereus (nitrocellulose powder more so than black powder); 2. When the shot is fired numerous bacteria survive and are forced out with the gunsmoke from the weapon and thus find their way into the wound. In principle, blank cartridge propellant thus exhibits as much potential for wound infection as the skin germs. Clearly, the species B. cereus is prominent in this context. For open injuries even with ‘harmless’ blank weapons, an antibiotic prophylaxis should always be administered.     

Air guns: toys or weapons?

Air guns and blank guns may appear relatively harmless at first glance, but they are, in fact, potentially destructive, even lethal, weapons. Approximately 2 to 2.5 million nonpowder firearms are sold annually, and again approximately 12.9 per 100,000 population are treated for such injuries in hospital emergency departments each year in the United States. Unfortunately, these guns are considered to be a toy for children. Therefore, incidents of air gun injuries are gradually increasing. Although such injuries may initially be considered trivial, it may signify severe internal tissue pathologies. These apparently trivial injuries may have catastrophic consequences if unnoticed. In this study, we report 4 cases with head injury due to a shot by these guns. The cases indicate that these people had used the guns belonging to their parents for the purpose of suicide. The cases also show that these machines are not innocent.     

An Unplanned Complex Suicide by Multiple Blank Cartridge Gunshots and Cutting

Blank firing guns are readily accessible in most countries due to an absence of legal regulations. These weapons are capable of causing lethal injuries. We report a rare case of secondary (unplanned) complex suicide committed with a knife and blank cartridge pistol. A 59‐year‐old man was found dead with three superficial incisions in his neck and a gunshot wound to the chest. The external examination revealed an entrance wound in the left chest region consistent with contact shooting. The appearance of a muzzle imprint suggested two discharges. The autopsy showed a slightly hemorrhaged but otherwise intact pericardium, blood in the pericardial sac, and a channel‐like defect in the anterior wall of the left cardiac ventricle. The cause of death was attributed to cardiac tamponade. To the best of our knowledge, this is the first reported case of unplanned complex suicide involving an unmodified blank firing gun.     

Suicidal shot in the mouth with an unmodified blank cartridge pistol

In the medicolegal literature reports of suicides with weapons designed for self-defence, especially gas pistols, are rare. We report on a suicide of a 54-year-old woman who fired a fatal shot in her mouth with an unmanipulated blank cartridge pistol, make R?hm RG 8, calibre 8 mm. The autopsy findings (lips and mucosa of the buccal vestibule without injuries, but extensive lesions of the tongue and the middle and rear third of the smooth palate) suggest that the shot was fired - as observed by a witness - with the barrel of the weapon inside the oral cavity. Both macroscopic inspection and histological investigations excluded the possibility that death was caused by an injury of the brain, in particular the brain stem. The immediate cause of death was deep aspiration of chyme with concurrent aspiration of blood.     

Homicide by unusual‐edged weapons: Forensic considerations of two cases

Homicide by stab wound is common worldwide. However, the use of unusual edged weapons is rarely reported in the forensic literature. Here, we report two cases of homicide involving a Japanese sword, or katana, and a sickle. Both of these weapons can create either stab or incised wounds with some particularities. In our cases, characteristics of the external wounds, internal injuries, and the depth of penetration raised the possibility of an unusual weapon. Meticulous forensic examination of these injuries (morphological characteristics, depth of penetration, trajectories, and cut marks in the bone) may allow the forensic expert to determine the type of weapon used.     

Death caused by projectile guns--a retrospective analysis of 34 cases in Berlin and Hamburg

The autopsy material of the institutes for forensic medicine in Berlin/GDR and Hamburg was analyzed retrospectively (period from 1961 till 1987; 70,000 autopsies) for fatalities caused by "humane killers" (n = 22) and stud guns (n = 12).-Epidemiological, criminological and morphological findings: The decreased were all men aged between 18 and 75 years (mean 48 years) except one 61 year-old paraplegic women who was killed by her husband with a humane killer. The great majority of cases consisted of suicides; two accidents at work were caused by stud guns. These unusual weapons are normally used by skilled people (i.e. butchers or constructional workers respectively). The fatal wounds were situated at the head, especially the forehead, seldom at the nape of the neck or in the mouth, or sometimes in the chest when using stud guns. Combined suicides (especially together with hanging) are not unusual. Survival periods (with or without acting capacity) can range between minutes or even months (after neurosurgical intervention).-The frequency of such unusual and overall rare cases did not raise during the investigation period.     

Gunshot injuries of the brain caused by air pressure guns

The article describes the historical and legal basis, as well as the ballistic criteria of injuries caused by air-rifle shots to the head. Six of our own cases of craniocerebral air-gun pellet injuries are discussed and critically assessed, using the results communicated in other papers as the basis of the discussion. The different post-traumatic complications, including the histopathological reaction of the brain to lead-pellets, are considered. The literature is reviewed and the indications for stereotactic removal or craniotomy of intracranial air-gun pellets are discussed. Air rifles, while occasionally the cause of serious head injuries, are rarely thought of as lethal weapons. However, this article illustrates the potential penetrating power of the air-gun pellet, a fact not always appreciated by physicians.     

Mandibular fracture caused by absolute close-range gunshot with a blank cartridge fright weapon]

Bony injuries caused by starter's pistols were repeatedly observed in the form of fractures of the temporal squama and other thin osseous lamellae; in experiments rib fractures could also be produced. In the presented case a contact shot from a blank cartridge pistol caused a fracture of the lower jaw (transverse fracture with a bone fragment split off in reg. 46). The friend of the 17-year-old victim had fired a shot to the right mandibular region during an argument. In the depth of the gunshot entrance wound, which communicated with the oral cavity, intense soot deposits were found as signs of the contact shot.     

Characteristic of injuries inflicted by a blank gunshot

The analysis of the data published in the special literature indicates that forensic-medical aspects of the injuries inflicted by blank shots fired from a variety of small-arms weapons remain poorly known or virtually unexplored. Despite considerable variability of such injuries, their forensic-medical examination should include three basic components, viz. the proof of the absence of the injurious action of the shot, differential diagnostics of the consequences of injuries attributable to each traumatic factor of the shot, and experimental simulation of the damages to the human body and the clothes taking into account concrete models of the weapons and the blank cartridge.     

Morphology and phenomenology of death by kicking (II)

In the years from 1982 to 1995, 20,504 autopsy cases were examined at the Departments of Forensic Medicine in Hamburg and Greifswald. In 103 cases death was caused by kicking. In the Greifswald area, the occurrence of kicking as the cause of death could be demonstrated in 68 cases (30% of all homicides), which is in contrast to the observations in Hamburg, were kicking amounted to only 2.5% of the homicides. Most of the victims (average age 44 years) were under the influence of alcohol (mean blood alcohol concentration 1.75/1000), and most were on social support. The victims often showed other signs of blunt trauma such as blows with the fist and strangulation. In a few cases, cutting and stabbing wounds were also found. In the majority of cases death was due to severe haemorrhages and aspiration of blood in addition to the direct effects of the head injuries. The crimes were committed by one person in 46 cases, two in 20 and three in 4 cases. The perpetrators (average age 27.6 years) were always younger than the victims. Case reports show that fatal kicking was mostly triggered by relatively trivial arguments. None of the incidents were preplanned by the perpetrators. In contrast to an expected higher incidence of kicking deaths in the urban area of Hamburg, these crimes occurred ten times more frequently in the rural area of Greifswald.     

Body Transportation after Homicides: Offender and Offense Characteristics

Body transportation is defined as moving the body of the victim from the scene of a homicide to another location. We analyzed data on 513 South Korean homicide cases with convictions to compare 104 homicides involving the transportation of victims’ bodies with 409 homicides that did not. Offenders who transported their victims’ bodies were significantly younger and more likely to be related to the victims and were less likely to use sharp instruments and more likely to use blunt instruments or strangle the victims than offenders who did not. Victims of homicide involving body transportation were more likely to suffer injuries to the neck and head and less likely to suffer injuries to the torso. Finally, offenders who transported victims’ bodies were more likely to have planned the offense and destroyed evidence. The present findings have practical implications for police investigations.     

Neck injuries caused by being run over by a motor vehicle

We report a homicide involving the use of a motor vehicle and simulating a traffic accident. This observation was the reason for a retrospective analysis of neck injuries in victims of traffic accidents, in which a person has been run over (RO) by a motor vehicle. The autopsy material of two institutes from 1990-1996 was used. The following findings were obtained in 63 victims: laryngohyoid fractures (LH-fx): 10 cases (16%) with a clear difference between the institutes (22% versus 7%). This resulted from examination with special regard to such injuries in many cases at one of the institutes, whereas only autopsy reports were taken retrospectively from the other institute. Five of these cases had suffered only minor LH-fx (as seen frequently in strangulation), although extensive run over (RO) injuries of the other cervical tissues were present. All LH-fx were caused by direct compression of the neck; in eight of the cases they were combined with mandibular fractures. Petechial hemorrhages (petH) at the eye lids/conjunctivae were seen in 19 cases (30%); 16 of these were related to thorax RO injuries, three to abdominal RO only. Four cases involved LH-fx, petH as well as cervical skin lesions and additional cervical soft tissue hemorrhages. Interpretation can be extremely difficult with this combination of findings if the character of the event cannot be established as accidental beyond doubt on the basis of the circumstances.     

Death by chainsaw: fatal kickback injuries to the neck

Each year over 3 million new chainsaws are sold in the United States. The operation of these newer saws combined with the millions of older chainsaws in circulation results in over 28,000 chainsaw-related injures annually. The majority of the injuries involve the hands and lower extremities with less than 10% involving injuries to the head and neck regions. Deaths while operating a chainsaw are extremely rare. The most common hazards associated with chainsaws are injuries caused by kickback, pushback, and pull-in. Kickback is the most common and poses the greatest hazard. Kickback occurs when the rotating chain is stopped suddenly by contact with a more solid area throwing the saw rapidly backward toward the operator. The cause of most injuries can be traced to improper use of the saw or poor judgment on part of the operator. We present two fatal chainsaw deaths; one with an older style saw, and the other with a modern type. In both cases the victims died from fatal injuries received to the neck region from a chainsaw kickback. The first case involved a 49-year-old white male operating an older style chainsaw with limited safety features. The second case involved a 38-year old white male who was operating a newer model chainsaw equipped with a low kickback chain in an unsafe manner.     

Characteristics of firearms and gunshot wounds as markers of suicide.

Data from a total of 1,200 cases that the Medical Examiner of Dallas County, Texas, ruled as suicide with a firearm have been compared with the results of forensic laboratory examinations and tests; 75% are with handguns and 25% are with long guns. The incidence of suicides by gender yields 82% males and 18% females, with the most common entrance site being the head. With regard to racial distribution of persons committing suicide, > 88% are white in the study population group, which is 76% white. Data are presented for the incidence of blood detected inside and on the muzzle end of the barrel of the firearm, and for the persistence of blood inside the barrel even after the weapon was discharged to obtain test bullets. The analysis of handwipings for primer residues shows that "positive" results are obtained for approximately 50% of the revolvers and approximately 32% of the pistols when the caliber is > 22. Other projects such as transfer of gunshot residues to the hand by simply handling the weapon, the incidence of single-contact wounds in homicide versus suicide cases, and the percent of positive identification of bullets with weapons submitted are described.     

Injuries and fatalities caused by gas-/warning weapons

Detailed report of 5 cases of violation with gas or warning firearms, 3 of them lethal. In one case a modified weapon (elongated barrel) and steel bullets were used, resulting in shot of the head with retained missile and lethal bleeding. In the other cases, regular weapons (8 or 9 mm cartridges) were used for contact shots; violation occurred only by the effect of powder gases. One of these cases was a suizide (lethal temporal gunshot), in the other cases shots by another person: a) shot against the arm with large soft-tissue damage (survived); b) and c) shot against the neck with exceeding rupture of the soft tissues, minimal damage of the neck arteries and in one cases bilateral tears of the hypopharynx. In this case a delayed death after primarily well operated injury occurred after 12 days by bleeding into the airways from ruptured external carotid artery.
