Indeed. It appears that her torpedoes and depth charges detonated as she went down. Still worth searching for whatever may remain of the wreck.
Actually they probably didn’t detonate on her trip to the bottom. Her hangar decks was strewn with several dozen 500 and 1000 lb. bombs removed from aircraft when they swapped the bombs for torpedoes. The hangar deck crews didn’t take the time to strike the bombs back down to the magazines. When the American dive bombers struck the avgas system was blown open starting huge fires on the hangar deck which also caused the bombs to explode. Probably a majority of her flight decks was destroyed before she was torpedoed by one of the escorts.
