In mid-July 1977, a 38 year old woman was sitting in her living room talking to her husband, when suddenly, mid-sentence, she stood up, and said very robotically, that she was going to go lie down for a while. Then she turned and walked away into a nearby bedroom. Sensing something was off with his wife, the husband followed her… What he would see, and hear, in that bedroom over the next 30 minutes, would not only scar him for life, but would also become some of the most infamous evidence ever used by police in a real murder investigation.
