"Standard forensic DNA profiling for human individual identification purposes is only successful in cases where a DNA profile recovered from a human biological crime scene trace matches that of a known suspect, who is directly available via police investigation or indirectly by searching criminal offender DNA database. However, there is an ""information gap"" in cases where a perpetrator is unknown i.e. has successfully escaped police investigation, or his/her DNA profile is not in the criminal DNA database. The VISAGE Project aims to bridge this information gap by providing reliable information allowing to construct a composite sketch of an unknown trace donor from trace DNA left behind (also referred to as Forensic DNA Phenotyping, FDP). By using this ""biological witness"" FDP outcome during police investigation, the search for the unknown perpetrator will be focused towards the most likely person, or group of persons, meeting the DNA-based composite sketch outcomes. To achieve this overall aim, the VISAGE Consortium had defined a series of objectives covering (epi)genetic research, prototype tool development, technical validation and implementation, consideration of ethical, societal, and legal dimensions, training and dissemination. In particular, VISAGE will allocate previous and establish new DNA predictors for as detailed as possible appearance, age and ancestry information. VISAGE will develop and validate prototype laboratory tool(s) based on targeted massively parallel sequencing (MPS) technologies for simultaneous analysis of the selected DNA predictors. VISAGE will design an integrated statistical interpretation framework, and will develop a prototype software, for combined consideration of the appearance, age, and ancestry information delivered by the laboratory tool(s). VISAGE will identify and analyze the main challenges for, and will make recommendations on, the ethically, socially and legally responsible implementation of FDP in EU Member States. At the final stage, the VISAGE Toolkit for constructing composite sketches from DNA traces will be implemented in the routine forensic DNA service environment of 8 EU Member States. These efforts will be accompanied by training the different target groups on the technical, interpretational, ethical, societal and regulatory issues of constructing composite sketches from DNA traces in forensic applications, and disseminating the major project outcomes to the relevant target groups and the wider public."
