It Is Said That Men with an Extra Y Chromosome in Their DNA Are Born Rapists.

It is said that men with an extra Y chromosome in their DNA are born rapists. I took the DNA test report, and the DNA in this report turned out to be the rare XYY. The deceased was a 23-year-old woman named Bai Jie. She died naked and tragically in her dormitory. Her mouth was filled with the murderer's bodily fluids and she was stabbed several times. The fatal injury was suffocation caused by a stocking strangled around her neck. This DNA is the body fluid information in her mouth. I asked people to go to the library to find matching DNA, and then I looked through the photos of the scene one by one. No murder weapon or knife was found at the scene, and no knife was missing from the kitchen. It seemed that the knife used in the crime was brought by the murderer himself. No fingerprints were found, only the footprints of an adult male.
