First case of illegal euthanasia in Spain: fatal oral potassium cyanide poisoning.

A fatal case of intentional oral cyanide poisoning in a tetraplegic patient whose repeated legal requests to be allowed to perform euthanasia had been refused, is reported. The postmortem provided no specific findings and the diagnosis was based on the toxicological analysis of the different samples available. Cyanide was determined in all biological (blood, vitreous humour, bile, urine and viscera) and non-biological samples_received (liquid found in a glass beside the body in the scene of the crime). The high cyanide concentrations in blood (21.5 mg/L) are consistent with death through cyanide poisoning. Also, the cyanide concentration in the water held in the glass from which the casualty presumably drank 81900 mg/L), and the high levels of potassium ion found (186 mEq/L), allowed us to conclude that the death was due to the intake of an amount of potassium cyanide between 500 and 1000 mg.

Forensic cases of seemingly ligature strangulation.

Many external injuries on the neck can often simulate ligature strangulation. This similarity could lead to mistakes or overestimation of these findings and consider them as violent deaths. Therefore, when the work of the forensic pathologist is to limit the external examination of body, the conclusions can be mistaken or wrong. In the present article four cases of apparent ligature strangulation are showed. All the autopsies were performed and completed with microscopical and toxicological examinations. During necropsic examination different causes of death, other than the initial suspected, were discobered.
