I recall that being reported, but I also recall reading something about requirng DNA identification at the time, which suggests severe injuries (burns?). It's also very possible that news at the time was inaccurate; for instance I can see news about bodies found in the water becoming 'drowned' in a news message. (not saying that did happen, just saying it's possible for that to happen. Remember news also keeps mentioning oxygen in our tanks).4 souls were recovered that had injury consistent with drowning early on, it is possible that they did escape the berthing area but by the time the got out and off the boat into the water they were incapacitated enough by smoke etc they succumbed.
I see no reason to even go near the suggestion of people 'want to ignore that'...
