premise: Crippa died a week ago at Santa Barbara Cottage Hospital, seven days after he ate a heaping plate of the deadly Amanita ocreata mushrooms, said his wife, Joan Crippa. Known as "death angel" for its snow-white appearance, the fungus has deadly toxins that worked their way through Crippa's system, sickening him and eventually causing his liver to fail. Family members had often warned Crippa against indulging in his passion for hunting wild mushrooms, an activity he learned from his Italian immigrant parents, his wife said.
hypothesis: Crippa's wife, Joan, was an Italian immigrant.
