Priscilla Davis, a platinum-blonde mother of three, arrived home late on a Monday night in 1976. It was a beautiful home, appointed with high ceilings, an indoor pool and picture frames hemmed with leopard skin or gold. There was a man in the kitchen. He was dressed in black and disguised in a women’s wig. “Hi,” the man said. Then he shot her in the chest. Priscilla screamed loud enough to beckon her lover, Stan Farr, from the master bedroom. Farr lumbered toward the kitchen as quickly as a 6-foot-9 man could move, where he encountered the intruder, who shot him twice. As he crumpled to the floor, Farr and Priscilla locked eyes. Two more shots rang out, and Farr was dead. As she recounted later to law enforcement, Priscilla pleaded for her life. She believed the killer to be Cullen Davis, her estranged husband of seven years and an oilman worth at least $250 million. They were in the midst of a messy divorce, and for the moment, she occupied their $4 million mansion in Fort Worth, Texas. But who was Cullen Davis? And how did an American multimillionaire become the prime suspect in such a horrific crime? Dark Capital is a limited-run series that explores the intersection of business, wealth and crime. It’s featured on Sundays.
