Homicide by sharp force in two Scandinavian capitals

In the Oslo and Copenhagen capital areas, 141 homicides by sharp force were committed in the ten-year period 1985-1994. This method accounted for 33% of the homicides in this period. Thirty-five percent of the victims were female, and most of the victims were between 20 and 50 years of age. The majority of the male victims were killed by an acquaintance, the females by their spouse. Sixty-five percent of the male and 37% of the female victims had alcohol in their blood. The majority of the female victims had lesions in 3-4 anatomical regions, while the males most often had lesions in only one anatomical region. Seventy-nine percent of the females and 36% of the males had self-defence injuries in the upper extremities. In 21 cases (15%) the offender was a woman, 19 of their victims being male; the weapon in these cases was most often a kitchen knife. Seventy-eight percent of the females and 49% of the males were killed in their own home. The most common circumstance was family row when the victim was female, while a fight was the most common circumstance when the victim was male. Three offenders committed suicide after having committed homicide(s) (seven victims; three offenders).     

Homicide by blunt force in 2 Scandinavian capitals

In the Oslo and Copenhagen areas, 77 instances of blunt force homicides were committed from 1985-1994, accounting for 18% of all homicides in that 10-year period. Fifty-four (70%) of the victims were male, often killed by an acquaintance during a fight. Almost 70% of the female victims were killed in their own home, whereas that was the case for only 30% of the male victims. The majority of the victims (of both sexes) had been hit in more than 1 region of the body. A female offender was encountered in 4 instances; none of their victims were children. Of the 3 children in the blunt force victim group, 2 were battered children. Many of the victims with a blood alcohol level of 0 turned out to have lived for some time after the injury.     

Homicides in two Scandinavian capitals.

In this study we investigated homicides in the two Scandinavian capitals, Copenhagen, Denmark and Oslo, Norway, for the 10-year period from 1985 to 1994. The total number of homicides was 431; 63.8% occurred in Copenhagen and 36.2% in Oslo. The average homicide rate was 1.6/100,000 in Copenhagen and 1.8/100,000 in Oslo. Blunt force, sharp force, and strangulation were the most common methods. Firearms were also used but did not account for >20% in either of the two cities. This is probably due to strict gun laws in both countries. There was no clear difference between the homicide victim populations in the two cities with regard to age, gender, or social and marital status. The proportion of alcoholics and unemployed persons was much higher than in the background population and to a similar extent in both cities, indicating that the homicide victim populations differ from the background populations. The perpetrator knew the victim in the majority of the cases. The most frequent motives or circumstances in both cities were fights, family rows, financial controversies, or jealousy.     

Asphyxial homicide in two Scandinavian capitals

In the Oslo and Copenhagen capital areas, 94 asphyxial homicides were committed in the 10-year period 1985-1994, accounting for 22% of all homicides in that period. Sixty-nine (73%) of the asphyxia victims were female. The most common method of asphyxiation was manual strangulation. Seventeen (18%) of the victims were below the age of 10, accounting for 59% of all homicides in that age group. Whereas 38% of the female victims were killed by their spouse, this was the case for only one male victim. The motive was not known in a great proportion of cases. Fifty-seven percent of the victims had been subjected to additional violence, and in this respect there was no difference between the sexes. In 12 of the cases the offender was female; in 9 such cases the victim was her offspring. More than half of the victims had no blood alcohol. When disregarding the victims less than 10 years of age, 33% of the male and 49% of the female victims had no blood alcohol. The crime scene was the victim's domicile among 72% of female and 52% of male victims. Forty-two percent of the female and 11% of the male victims above the age of 10 years were married or cohabitant.     

Homicide by fire

A study of homicide perpetrated by fire was performed on the case files of the Office of the Medical Examiner of Metropolitan Dade County in Miami, Florida, during the years from 1977 until 1984. A total of 26 cases were collected and analyzed as to age, race, sex, and the cause of death of the victim along with the blood alcohol content, the drugs detected at autopsy, and the blood carboxyhemoglobin level. Additionally noted were the geographic location of the terminal incident, the scene circumstances, how the fire started, who started the fire, and the reason for the fire. The most common victim was a 31-50-year-old white man who died from smoke inhalation while sober. Commonly, drugs detected were negative, and the carboxyhemoglobin levels were elevated. The fire occurred at "home" while the victim was sleeping. Usually, a flammable liquid was poured and ignited by a drifter who was a brief acquaintance and earlier involved in an argument with the victim.     

Homicide by burning

Compared to the total number of deaths by heat (burning, scalding), homicides by the direct effect of thermal energy (setting the victim on fire, pouring hot liquids over them) are rare; accordingly this subject is seldom dealt with in forensic and criminological literature. From our own autopsy material three cases are presented describing some peculiarities of homicide by heat. Sometimes additional findings (e.g., residual traces of gagging or tying) primarily point in the direction of homicide.     

Homicide by methane gas

Two cases of sudden death due to myocardial infarction which were associated external injuries on the chest are discussed here. Injuries were in the form of abraded contusions on the anterior part of chest. Both the cases were declared dead on arrival to the casualty section (Accident and Emergencies Department). In these cases, mention of injuries was not made in the inquest report. In both the cases, suspicion of foul play or the trauma induced myocardial infarction were ruled out by inquiring into the incidents by the autopsy surgeon. The cases highlight the importance of detailed history by the autopsy surgeon in cases of sudden death with associated injuries on the front of the chest.     

Homicide by decubitus ulcers

Traditionally, the only penalties for poor treatment of nursing home patients have been civil lawsuits against nursing homes and their employees by families, or fines and license suspension by government organizations. Recently, government agencies have become much more aggressive in citing institutions for the development of decubitus ulcers (pressure sores) in their patients. A few government institutions have concluded that in some cases, the development of ulcers with resultant death is so grievous that there should be criminal prosecution of the individuals and/or institutions providing care. A leader in this concept has been the State of Hawaii. In November 2000, the State of Hawaii convicted an individual of manslaughter in the death of a patient at an adult residential care home (a form of nursing home) for permitting the progression of decubitus ulcers without seeking medical help, and for not bringing the patient back to a physician for treatment of the ulcers.     

Homicide by insulin administration

This report describes a case of homicide by insulin administration and a study of the effects of storage conditions on insulin in serum. The study revealed insulin to be remarkably stable at refrigerator temperatures. Therefore, for forensic science purposes, insulin immunoassay data are interpretable even when serum is not stored by the standard laboratory method of freezing.     

Homicide by starvation.

Homicide by starvation is a very rare occurrence, especially when the victim is ambulant. This paper presents a case where the death of the individual went undiscovered for more than 3 weeks. A successful conviction for murder ensued. The paper also discusses social and pathological problems associated with this crime.     

Homicide and suicide by aircraft

A report of simultaneous homicide and suicide by aircraft is presented. This confirms the view of Phillips (Science, 201 (1978) 748–750), that despite the previous absence of similar reports in the history of civil aviation, such incidents may occur, and that therefore murder and suicide should be considered as a possible cause of aircraft accidents.     

Homicide by manual occipitoatlantal dislocation

Occipitoatlantal dislocation is usually seen as a fatal injury in traffic accidents and has rarely been reported as a consequence of a homicide. The authors report the case of a women presenting a fatal occipitoatlantal dislocation, the circumstances of which pointed to a homicidal origin. Blood extravasation surrounding the muscles of the posterior part of the neck as well as abnormal mobility of the cranio-cervical joint was noted during autopsy; thus a complete dissection of this region was performed. This led to the finding of a fracture of the left occipital condyle and of the left superior articular facet of the atlas. This case clearly demonstrates the need to perform a large, systematic, posterior approach to the upper cervical spine, completed by the opening of the skull around the posterior fossa, when injury to the cranio-cervical junction is suspected. In these cases, the classic anterior approach give poor information and poor dissection possibilities.

Homicide in Ireland

The homicide rate in Ireland is the lowest in Europe in the 1990's and has declined sharply during the 158 year period from 1837–1994. The rate has also remained stable in the 1980's and 1990's. These trends are contrary to the view held by the Irish public and the Irish and International media and raise questions about the reputation of the ‘'wild Irish'’ who emigrated to the U.S. and other countries in the 19th century.     

Homicide by intravenous injection of naphtha

A case of homicide by the intravenous injection of Energine, a petroleum distillate spot remover, is presented. This case is the only known homicide committed with naphtha. This elderly man had severe natural disease in addition to chest trauma sustained in the assault leading to death; however, the rapid injection of approximately 25 mL of Energine was the overwhelming cause of death.     

Interpretation of unusual wounds caused by firearms.

The interpretation of the range of fire of gunshot wounds requires coordination of information and observations from the autopsy surgeon, scene investigator, and laboratory analyst. Opinions based on incomplete information often lead to misinterpretation of the wound. The effects of interposed targets such as clothing, windows, and body parts are discussed. Case examples are given for interposed targets that cause confusing patterns and even lead to misidentification of the points of entrance and exit of the projectile in the body. The splitting of tissue in areas of bony prominence can be mistaken for evidence of discharge of a firearm at close range.     

Homicide in Singapore

Singapore has one of the lowest crime (and homicide) rates in the industrialized world. Since no prior published study has analyzed the patterns of homicide in Singapore, this study presents data comparing homicide patterns in Singapore to the U.S. Overall, the U.S. homicide rate was found to be 5 times greater than the Singapore rate. Variation between the sexes and across racial/ethnic groups was much less in Singapore than the U.S. The sharpest difference in homicide between Singapore and the U.S. involved gun homicides and the death penalty. Gun homicide rates in the U.S. were found to be 197 times the Singapore rate while the death penalty was utilized 15 times as often in Singapore.     

Suicide by firearms: a 15-year experience.

A retrospective review of 1704 cases of suicide involving firearms investigated by the Bexar County Medical Examiner's office between 1984 and 1998 was performed. The age distribution was similar in male and female victims, and the type of weapon was not associated with age. Approximately 78% of the victims used a handgun (87% of female and 76% of male victims). In 4.0% of head wound cases, the site of the entrance wound was the back of the head. Thus, this report refutes the common belief that all gunshot wounds to the back of the head represent homicides. In 1.9% of the cases, the wounds were inflicted at intermediate range. With handguns, the right temple was the most common site, but with rifles and shotguns, the most common site was the mouth.     

"Homicide by heart attack" revisited

The sudden death of a person caused by an arrhythmia that is induced by physical and/or emotional stress provoked by the criminal activity of another person is sometimes referred to as "homicide by heart attack." Published criteria for such an event relate to situations where no physical contact occurs between the perpetrator and the victim. Situations involving physical contact, but with absence of lethal injuries, are frequently treated is a similar fashion by forensic pathologists. Herein, we propose a set of modified criteria, which include cases where physical contact has occurred. Five examples of so-called "homicide by heart attack" are presented, including a 40-year-old man who was struck in the head with a wooden statue, a 74-year-old man who was punched in the jaw by a robber, a 66-year-old woman who was started awake by a home-intruder, a 67-year-old woman who struggled with a would-be purse-snatcher in a parking lot, and a 52-year-old man who was in a physical altercation with a younger man. In each instance, autopsy revealed the presence of severe, underlying heart disease, as well as absence of lethal injuries. In each case, investigative information was such that the emotional and/or physical stress associated with the criminal activity of another individual was deemed contributory to the death. The presumed mechanism of death in each case was a cardiac dysrhythmia related to underlying heart disease, but initiated by the emotional and/or physical stress.
