On June 24th 1966, a 13 year old girl, Cathie Ward was found dead after she spent a day horseback riding at Blacksnake Ranch. The ranch owner, Frank Davis, told police that she fell from the horse and her foot got caught in the stirrup. Then the horse dragged her through a field full of rocks and crystals. Frank Davis had a bad reputation around Hot Springs, Arkansas and for good reason. Cathie's death was ruled an accident but the investigation resurfaced after Frank was arrested for the murder of his wife less than a year later.
Bitty Martin wrote about this story in her book, "Snake Eyes." She was a close friend of Cathie Ward. She spent years working on it and interviewed over 50 people. I definitely recommend it to everyone.
