3、orting rate of these assaults has tripled nationally during this period,researchstatistics indicate that sexual assault remains as one of the most under-reported types of crime.Thesestudies also indicate that the ratio of persons committing sexual assault to the general population isfairly constant.
4、The rise,therefore,in the reporting rate of sexual assault reflects improvements madein U.S.society concerning how such reports are investigated and processed in the courts.Theseimprovements have occurred in the areas of the victims movement and victim advocacy initiatives bythe criminal justice sys
5、tem,improved police education and training,the womens movement andgender equality consciousness in society,sexual assault education in the schools and the public sectorgenerally,and the evaluation of clinical forensic nursing.The articulation of these standards carriesforward the spirit of these imp
6、rovements so as to serve the cause of justice in society.Although reports of child sexual abuse have also increased markedly in recent years,these reportsare even more difficult to substantiate than adult reports.Many children are too young to realize thatcertain kinds of physical contact by others

8、n to them or their families if they report the abuse,orthat they were in some way responsible for it.Traditionally,the successful prosecution of both adult and child sexual assault cases has beendifficult.The victim often is the only witness to the crime.Consequently,the documentation ofphysical inj
9、uries and the collection of trace evidence may provide important corroborating evidence.Meticulous attention to detail in the collection and preservation of evidence combined with anempathetic concern for the victim,and a respect for the legal and human rights of the suspect isrequired.Within the co
10、mmunity,this process is known to be facilitated by using trained forensicexaminers in the setting of a multidisciplinary team.1.Scope1.1 This guide covers the basic components for the devel-opment of a sexual assault investigation protocol,with specificattention to the examination of assault scenes,
11、victims andsuspects of sexual assault,the recovery of testimonial,physical,and behavioral evidence,and the preservation andcustody of physical evidence.1.2 This guide outlines procedures requiring the experienceof experts in a diversity of fields.A multidisciplinary teamapproach to sexual assault in
