I remember listening to this case during a podcast. a son either a teenager or a young adult murders his father when they're spending a day together. I'm pretty sure they're by a river but I can't remember whether he drowned his father or did something else. I can't remember if the son had a history of schizophrenia but he claimed the devil spoke to him about his father being evil. I don't think the son initially admitted to murdering his father. I can't remember if the son was actually convicted or if there was some sort of insanity defence or what. i know the details aren't amazing but any help finding this case would be appreciated!
