A GC/MS-method is described for the screening, detection and determination of the commonly used drugs amphetamine, methamphetamine, MDA, MDMA and MBDB in small blood samples and bloodstains using solid phase SPE columns and a pipetting robot (Gilson Aspec XL). The detection limits are in the order of 0.03 to 0.08 microgram/L and the correlation factors between 0.9982 and 0.9998. Furthermore the stability was investigated covering a storage time of 64 days. The method has proven useful in forensic cases with only small sample volumes or bloodstains. 相似文献

Depending on local conditions it may happen from time to time that no officer involved in the previous investigation is present during the forensic autopsy. In this case, the post mortem examiner often has to rely solely on written documentation concerning the identity of the deceased. The authors report a case where the body had already been mixed up with another body by the undertaker prior to the inspection by the police. In spite of clear distinguishing characteristics in the written documentation, this led to the wrong body being autopsied. For the post mortem examiner, the only safe way to identify a body seems to be the presence of persons who had known the deceased or of police officers as acknowledging witnesses. If these conditions are not given, other means of safe information on the identity are called for, for example a "police body card" similar to an evidence card. 相似文献

The human brain shows a very high density of functionally important structures. Even small lesions may therefore cause clinical symptoms. Penetrating gunshots to the head are presumed to cause immediate incapacitation by subsequent disturbance of cerebral functions. The authors discuss anatomical and functional principles of the terms action, capacity to act and incapacitation and report two illustrative cases with lack of incapacitation following gunshots to the head. 相似文献
