Multiple deaths from argon contamination of hospital oxygen supply

During the course of routine hospital surgical procedures, three patients lapsed into hypoxic cyanosis. Two expired immediately, another after four days of coma. Investigation of the hospital's central liquid oxygen tank revealed that it had been refilled recently and was labelled both "oxygen" and "argon." Mass spectrometric analysis of gas sampled from the questioned tank revealed a predominance of argon. A discussion of the sampling technique, method of analysis, role of the criminalist, and causes of this accident is presented.     

"False confessions" and identification with the aggressor: another forensic misuse of a psychiatric concept

Some psychiatrists misuse theoretical concepts beyond their generally accepted dimensions in an attempt to support a conclusion favorable to a litigant or defendant. In the case presented, the concept of identification with the aggressor was used in an attempt to eliminate or minimize the effect of a confession and to buttress the claim that the confession itself was false. Quotations from the actual reports and testimony are used to reflect both this tactic and the context in which these issues were pursued, including a rather startling admission by the psychiatrist dealing with the thoroughness of his professional effort. A brief history of "identification with the aggressor" is presented, a history which contrasts with its application to rather routine police questioning. Similarly, skepticism is clearly merited when a psychitrist testifies as to truthfulness or falsity of a statement.
