Researchers at Lund University in Sweden are developing a method using environmental DNA (eDNA) to aid police investigations. According to geneticist Eran Elhaik, all organisms leave DNA traces in their surroundings, creating unique environmental signatures. This technique could link objects like weapons to specific locations even when fingerprints or human DNA are absent, making it harder for suspects to conceal their whereabouts.
