A woman survives a brutal attack… only to die 5 years later. And now Dr. G wonders if her death is somehow related to that assault. Then, a man tumbles 15 feet to the ground. But Dr. G believes there may be more to this case than meets the eye.

The woman had been sexually assaulted, stabbed repeatedly, and left for dead. She survived, and gave police a detailed description of her attacker. When someone who fit that description practically turned himself in, police were sure they had their man... until the DNA evidence proved them wrong.
