Some areas where digital forensics can support the addressing of legal challenges linked to forensic genetic genealogy

Abstract

Forensic genetic genealogy (FGG), also known as investigative genetic genealogy (IGG), produces investigative leads in criminal cases where unidentified DNA is discovered at the crime scene and does not match any profiles in criminal databases. It works by comparing crime scene DNA samples to public or private genealogical databases to identify potential familial relationships and narrow down suspects or identify unknown individuals. Although the fields of FGG and digital forensics (DF) work with different types of evidence and techniques, and consequently develop independently, they share several common characteristics. This study aims to demonstrate that despite their independent development and differences, the experiences of progress in DF field can be utilized in some respects, especially concerning the protection of the rights of the individuals concerned. The aim of this article is to outline some areas where DF can provide assistance in dealing with ethical and social challenges that FGG must address.
