Death time estimation in case work. II. Integration of different methods.

The mean value of the time of death is not reliable because of the great variability of the time-dependent criteria of dead bodies. However, it is possible to narrow down a reliable time period for a stated death by means of the lower and upper limits of error of different criteria. The external data of lividity, rigor, mechanical and electrical excitability of facial muscles and the chemical excitability of the iris have all been gathered from literature, chronologically arranged and clearly presented. After rectal temperature measurement and a corresponding nomogram reading, it is simple to choose other suitable criteria and to integrate them with the aid of a chart thus producing a rational and practical procedure for use at a scene of crime.

Estimating time of death from measurement of the electrical excitability of skeletal muscle.

Post-mortem contraction was measured using sensitive force transducers inserted into human muscle. The muscle was stimulated using rectangular impulses of 1 sec duration and known current intensity. After some time, a noticeable change of the muscular contraction occurred, from a two-peak to a one-peak shape. The maximum force of the muscular contraction using a stable current intensity decreased with time since death, but relaxation time increased. The decrease of the maximum force and the increase of the relaxation time were used as criteria for extrapolating the time since death in a random sample of 50 bodies. The calculated 95% limits of confidence were 2.85 h (decrease of the maximum force) and 2.7 h (increase of relaxation time) up to 13 hours post mortem. The calculated 95% limits of confidence were checked on an independent sample of 21 bodies and proved to be reliable.

[Medical and legal problems of multiple death certificates].

In cases of unnatural death and unclear manner of death the police has according to section 159 StPO to inform the prosecution. The prosecutor has to decide how the case shall be handled. Independent inquiries or even independent handling of the case by the police are not scheduled. For legal purposes it is not possible to induce another doctor to issue another death certificate with the manner of death certified as natural.

[Child neglect death of an infant by faulty nutrition].

A 3 month old child was treated in hospital for "toxikosis and prolonged gastroenteritis". The child required a special diet. The parents picked up the child in hospital and brought it home against the device of the doctors. 26 hours later the child had died of severe exsikkosis (loss of 17% of body weight within one day). Using immunological methods (Ouchterlony test) we were able to demonstrate the child was fed with contraindicated food although the doctors had pointed out that the child needs a special diet. The parents were sentenced at court in two instances for manslaughter.

[Duration of the fire and degree of charring of a burned cadaver].

A 37-year-old woman was found dead severely charred in the bedroom of her house. The autopsy revealed as cause of death a strangulation of the neck. On the basis of the decomposition of the body the experts were asked for a statement on the duration of burning. There seems to be only little medicolegal experience on the duration of burning to a defined state of decomposition. Based on observations during cremations published in the literature and experimental burnings a burning time of approximately 20 minutes (after temperatures of more than 700 degrees C had been reached) is supposed to be sufficient to produce the present state of the body.

[Death in inverted head position].

A 56 year old man was found suspended in a sack in a head down position. Circumstances and autopsy findings are discussed. The leading pathophysiological mechanisms causing death are thought to be asphyxia due to compression of the chest and insufficient blood supply to the heart due to the head down position. The pathophysiological dysregulation of circulation in a head down position is discussed.

[Diagnosis of carbon monoxide poisoning following embalming and exhumation].

Clots of blood, which were found in the cardiac ventricles at an autopsy of an embalmed corpse, were to analyse for carbon monoxide. It was not possible to determine reliably the CO-Hb-content of the blood clots with the known methods. Therefore a new procedure was developed. Carbon monoxide was released by a solution of nitric acid and determined gas chromatographically by a headspace method. In the same vessel the iron-content of the sample was measured after decomposition with atomic absorption spectrometry. This procedure is especially suitable for samples like putrid or heat-clotted blood.
