The case history of a 51 year-old man with paranoid-hallucinatory schizophrenia is presented. Very intensive autoaggressive actions (cutting off the ears, partial amputation of the penis, eating of the amputated pieces, sawing off the left lower leg) led to very unusual autopsy findings (i.e. the glans of the penis was found in the colon). The cause of death was prolonged exsanguination.
In cases of CO-poisoning in vehicles accidents have to be reviewed. Old automobiles or untypical discovery without manipulations have circumstantial evidence. This proceeding is demonstrated by two casuistries. The argumatative force of the first appearance is not sufficient to give reasons for private-law consequences.
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.

31 cases of criminal dismemberment or mutilation were investigated in the period from 1959 to 1987 at the Institute of Forensic Medicine in Hamburg. With regard to all legal autopsies the average frequency was about 1:500. A distinct increase of the number of cases is noticeable within the last years; i.e. 1984 there were 6 victims. Our study enclosed the autopsy findings, the police investigations and the available court records. 12 cases were classified as defensive and 14 cases as offensive dismemberment of bodies; 2 cases of necrophilous dismemberment occurred after stealing the corpse and 3 victims were killed by intravital decapitation or mutilation. The victims were of all ages, but mainly between 20 and 60 years old; 22 of them were female and 9 male. 23 perpetrators could be identified; 18 of them were male and 5 female, most of them were between 30 and 40 years of age. The psychiatric expertises classified 17 of the perpetrators as "normal", 3 as abnormal and 3 as psychotic. Many morphological and criminological details concerning victims, perpetrators, used instruments for killing and dismembering, elimination and identification of the dismembered bodies and some juridical aspects are presented.

The professional access to weapons plays a role in the choice of suicide instruments. Light and signalling ammunition is used by police forces, in the military, in sports, and professional navigation. An unusual suicide of a shipowner by means of a signal-pistol is presented. The signal cartridge was shot into the head. Penetrating the skull the cartridge entered the brain. The burning-out of the signal-set--taking about 10 seconds--initiated a flat-burning.--This case shows once more the dangerous misuse of light and signal ammunition.
Deaths by fire-arms investigated at the Institute for Legal Medicine of the University of Hamburg were analyzed retrospectively since 1966. Among 70,000 deaths (33,000 autopsies) there were 838 fatalities caused by gunshots (about 30 cases per year). One third were classified as homicides, the others as suicides, only 3% as accidents. Almost the entire number of suicides was committed by men (relation male:female 20:1), whereas the proportion of women was higher among the homicides (ratio male:female 3:1). Details referring to the age of the victims, profession-coherence, alcohol-influence, capacity to act and survival-time are analyzed. The kinds of arms, and bullets (with special reference to self-made firearms), criminalistical aspects (i.e. differentiation between homicide and suicide, gun in the hand), morphological findings (i.e. nuchal and oral shots or bullet-related embolism) are introduced.
The autopsy on an body recovered from the water showed evidence of drowning and, in addition, the occurrence of extensive intramuscular bleeding on the neck, in the area of the shoulder girdle and the upper arms. There was a suspicion that criminal violence had been used, and the police carried out extensive investigations; these were inconclusive. The subsequent histological examination of the affected musculature revealed "reactive" changes throughout which corresponded to post mortem damage. The case presented here serves to illustrate the usefulness of muscle histology for differentiating between the occurrence of intramuscular bleeding before and after death; the corresponding histological criteria are outlined.
Guns may occasionally leave traces on human skin, for example by compression/impression of the tissue (esp. in the area of livores), by contact-transfer of dirt, oil, and rust, or by forming the pattern of blood-smears. The case of a 31-year-old drug-addict is presented in detail: The man committed suicide by shooting himself (entrance hole under the chin). When the dead body was found there was no weapon at the scene. By careful securing of evidence and analyzing the pattern of metallisations (identified as rust from the old pistol) it was reconstructed that the suicident held the pistol (identified as Russian Tokarew TT33-7.62 mm) in his hand for many hours postmortem until it was removed by an unknown thief.
Fatalities due to gunshot injury by hunting firearm or during hunting, that had been investigated in the Institute of Legal Medicine of Hamburg University during the last 20 years, were retrospectively analyzed from the view points of epidemiology, morphology, criminology and ballistics. Thirteen accidents, 23 suicides and 13 homicides were included in this study. Female victims were observed in only 2 cases. In the accidents, the age of the most victims ranged from 30 to 60 years. Seven of 13 accidental victims killed themselves; remaining 6 were shot by other hunters. Nine accidents happened during hunting. The most frequently used firearm in cases of suicide and homicide was a shotgun whereas accidents preferably occurred with rifles. In some homicidal cases pistols were also used. The entrance wound was localized mostly in the head, neck or breast. Shooting in the mouth was observed in many suicidal cases. Although many victims were shot in the hunting ground, 15 of 23 suicides were performed at home. In 3 homicides which occurred in the hunting ground, the murderer committed another crime with the robbed hunting firearm of the victim. Three accidents occurred during training in the shooting-gallery. Blood alcohol concentration (BAC) was determined in 28 cases. Different degrees of drunkeness were observed in 2 self-inflicted accidents, 5 suicides and 2 homicidal cases. No BAC determinations were performed on the shooters. Ten case histories are presented. The discussion concentrates on the effect of the kind of firearm and ammunition on the appearance of the wound, prevention of accidents, and the principles of reconstruction, especially concerning the differentiation accident/suicide. The forensic expert investigating gunshot injuries during hunting should have personal experience in this field. The most frequent cause of accidents was careless handling of the loaded firearm and violation of invulnerable rules for safety during hunting.
The case under discussion of a burn victim with dot haemorrhages into the caudal brain stem confirms other observations which have only rarely been published that these dot haemorrhages are not necessarily the sequelae of an intra vitam trauma. A reliable assessment of such cases demands a comprehensive pathologic and if possible neuropathologic autopsy including follow-up investigation considering police inquiry.
