A 24-year-old intern killed by an African lion at a California wildlife sanctuary died almost instantly after the big cat broke her neck, a coroner said on Thursday, amid media reports that the animal may have escaped from its pen to attack her. The Cat Haven, a private sanctuary east of Fresno, remained closed on Thursday, a day after Dianna Hanson was killed by a 350-lb (160-kg) male Barbary lion named Cous Cous that attacked her inside an enclosure. Hanson was from the Seattle area.
