The release of the National Academy of Sciences report Strengthening Forensic Science in the United States: A Path Forward, a resulting emergence of the Organization of Scientific Area Committees (OSAC) made up of five Scientific Area Committees (SACs) which report to a Forensic Science Standards Board (FSSB) for Forensic Science under the development coordination of the National Institute of Standards and Technology (NIST), emerging technology in various fields such as new and innovative DNA technologies, imaging workstations incorporating comparative analysis software for forensics and law enforcement, and the President’s Council of Advisors on Science and Technology report (PCAST), etc. All which are worthy of attention and discussion; however, the scope of this handbook does not allow attention to direct discussion of such occurrences except to potentially make reference as they relate to the physical evidence of forensic science that is the application of various sciences to law. The need for proper recognition, collection, and preservation of physical evidence is apparent to all who are involved in the criminal justice system. Physical evidence can directly or indirectly lead to the resolution of a crime. Charging and prosecuting decisions may be affected by the quality of the physical evidence supporting the case. The United States and Wisconsin Supreme Court decisions have placed great emphasis upon physical evidence in criminal cases. The Wisconsin State Crime Laboratory provides an important link between collection and court presentation of such evidence—most agencies within the state rely on the Laboratory for forensic examinations. It sometimes happens, however, that materials submitted to the Laboratory prove inadequate for proper analysis, or that improper collection or packaging methods destroy valuable evidence. It is unrealistic to expect that all submitters will know how to collect evidence in the i Preface - Introduction manner required by the Laboratory, however, submitters should have at least general knowledge of proper techniques to guide them. This handbook is offered in the belief that increased knowledge leads to understanding and that understanding leads to excellence. It was written to provide information regarding Laboratory requirements surrounding collection and preservation of physical evidence. This handbook is not intended to be a comprehensive treatment of all of the factors involved in criminal investigation. Because the laws and legal precedents concerning collection of physical evidence are subject to change, it is impossible to give specific, up-to-date information on acceptable procedures. Therefore, it is imperative that during an investigation, close liaison is maintained between the prosecutor’s office and persons responsible for the collection of physical evidence. The staff of the Wisconsin State Crime Laboratory has revised and updated this 9th edition of the Handbook with intention that it will continue to be of great value to those who use it. Gratitude and acknowledgement is expressed to laboratory staff members for their many contributions to the work and to the Wisconsin State Crime Laboratory colleagues in other Divisions of the Department of Justice who have assisted in seeing this revision completed. Special acknowledgement is made to Crime Laboratory Bureau Technical Unit Leaders, the Wausau Forensic Imaging Unit, and management. ii Introduction Wisconsin State Crime Laboratory Bureau The first Wisconsin State Crime Laboratory, located in Madison, was created by the Legislature in 1947. A second laboratory opened in the Milwaukee area in 1975. The Wausau Laboratory opened for business in 1991. Since the last edition of this handbook, the three Laboratories became the single State Crime Laboratory Bureau and continues to provide technical assistance in criminal matters when requested by authorized parties. Mission Vision To promote excellence To search in analysis, training To search for for the truth service to the through science community and and to lead our organization and shape the with integrity and advancement uncompromising of forensic quality. science.
