There was a vicious attack on a young lady resulting in her death. Her body had dozens of injuries including a knife wound to the chest. She was partially unclothed. Her body and clothing were tested for DNA. Usable DNA was found only on her underwear. Lab analysis showed that it was a mixture from two unidentified females. Someone confessed to this crime was it a woman? If a man confessed to this crime and a link through evidence other than DNA could be established, should he stand trial for the murder, or should law enforcement continue to search for the two mystery women?
