when did we start using dna to solve crimes
DNA profiling The modern process of DNA profiling was developed in 1984[5] by Sir Alec Jeffreys[6][7][8][9] while working in the Department of Genetics at the University of Leicester.[10]
Forensic science The first written account of using medicine and entomology to solve criminal cases is attributed to the book of Xi Yuan Lu (translated as Washing Away of Wrongs[5][6]), written in China by Song Ci (宋慈, 1186–1249) in 1248, who was a director of justice, jail and supervision,[7] during the Song Dynasty.
