When hunters reported finding a skull in a Texas canyon, police immediately began an investigation. At the scene, they found bits of clothing, a woman's shoe, some small bones and a strand of hair. An anthropologist determined the victim was a Caucasian woman, and that she'd been stabbed repeatedly. A forensic artist reconstructed her face, and the image was released to media. Eventually, police learned who she was. Now all they had to do was find her killer.
