Forensic genealogy. Social, ethical, legal and scientific implications

Abstract Despite the advances in investigative techniques in Forensic Genetics, there are still a large number of unsolved criminal cases. We have recently seen the birth of a new forensic discipline called forensic genealogy or investigative genetic genealogy, which allows to us resolve satisfactorily many of these cold cases combining DNA analysis technology with genealogical search tools. The potential and risks of this new research strategy are manifest. We must maintain a balance between personal privacy and personal interests on the one hand and on the other, public security, the good of the community and the resolution and clarification of criminal acts, requiring a social, legal and scientific debate that clarifies all these aspects and enables adequate legal regulation of these practices.
