On Feb. 9, Billy Jack Haynes, 70, was arrested on suspicion of murdering his wife Janette Becraft, 85. As of this writing, he has not been charged with a crime. The arrest is a bleak coda to an unusual life. Haynes was Oregon’s best-known professional wrestler, standing astride two eras: the regional, rickety wrestling promotions that won local allegiance, and the slick, cable-televised World Wrestling Federation.
