emerging investigative tool that combines advanced DNA analysis with traditional genealogy to help identify suspects through commercial DNA databases.</span></div></div><div class="block-content"><div class="styles__Container-sc-1ylecsg-0 goULFa"><span>The technique first gained widespread public recognition after it was used to identify and catch the "Golden State Killer", former US police officer Joseph James DeAngelo, in California.</span></div></div><div class="block-content"><div class="styles__Container-sc-1ylecsg-0 goULFa"><span>Unlike standard forensic DNA profiling, which examines 21 markers, FIGG analyses hundreds of thousands of genetic markers, enabling investigators to identify extended familial relationships, sometimes as distant as third or fourth cousins.</span></div></div><div class="block-content"><div class="styles__Container-sc-1ylecsg-0 goULFa"><span>These genetic markers are compared against two public genealogy databases – GEDmatch PRO
