Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThe meaningful analysis of physical evidence recovered in sexual assault investigations
3、requires notonly careful attention to the preservation of easily damaged or degraded biological materials but alsothe transmittal of a clear description and explanation of that evidence for the examining scientists/analysts/criminalists. This description should include the source of, and relationshi
4、ps between,different evidence items and is sometimes referred to as a “case synopsis.” The more information theanalysts have at their disposal concerning the circumstances of the assault and the relationship(s) ofthe victim(s) and suspect(s), the more successful their efforts will be in resolving qu
5、estions in theinvestigation. Failure to adequately document and report this information in the request for scientificanalysis could lead to the application of useless tests of the evidence that may destroy materials betterused in other more meaningful examinations.1. Scope1.1 These specifications de
