The purpose of this paper is to formulate recommendations for the disclosure of biological traces in the laboratory and the handling of forensic evidence submitted for identification tests, recommended by the Polish Speaking Working Group of the International Society for Forensic Genetics. The paper organizes the knowledge of the most relevant stages of preliminary analysis of biological traces based on both literature sources and those resulting from years of research practice. Recommendations formulated in the course of multi-stage expert consultations contained in this study should be used in the development of laboratory procedures applied during the execution.

Almost 40 years have passed since Alec Jeffreys’ seminal publications on the use of repetitive DNA marker analysis for human identification. The analysis of STR markers using multiplex PCR methods that followed this discovery has become a standard test for human identification. These methods also have investigative value. They are useful in the search for an unknown perpetrator through mass DNA testing as well as through forensic DNA databases. Another breakthrough is the analysis of long-range relationships. The ability to establish long-range relationships has enabled investigators to find the perpetrator of a crime, even in the absence of investigative hypotheses, by analysing the genealogical links recorded in our genomes. Modern DNA analysis not only provides strong evidence to be presented in court, but can also provide useful investigative leads when the identity of the perpetrator is unknown to the authorities.

DNA testing for investigative purposes: description of the perpetrator

The results of research projects to understand the diversity of the human genome have opened up new avenues of biomedical research and provided new tools for human identification studies. Genome wide association studies and epigenome wide association studies have enabled the identification of DNA markers that have been implemented and validated as predictive tools in the field of forensic DNA phenotyping. In the age of genomics, the study of biological traces can reveal the biogeographical ancestry, physical appearance, age and lifestyle of the perpetrator. The combination of different methods, including forensic genetic genealogy and prediction of phenotypic features, offers the possibility of significantly narrowing down the pool of suspects, thereby significantly improving the process of solving criminal cases. In general, a limitation is the availability of effective methods for large-scale DNA analysis that would ensure the forensic level sensitivity of the test.
