No. Because it's a common pattern in media reporting to embargo news stories.
There is an informal twitter service run by a group of BBC reporters called tomorrow papers today.
They publish the front cover story before publication.
I've seen on occasion certain stories or photos deliberately blacked out.
It's also not uncommon practice to get a story and sit on it whilst trying to get 'exclusives' with family members or celebrities in exchange for not publishing sooner under the guise of being nice.
You also have issues with fact verification (BBC often delay publication for this pending getting reputable sources). Or for what are deemed ethical reasons (some media outlets have considerable less concern for this. I will make the note here that if you are a media outlet who employs someone then you may have greater cause to do this because of the impact on the rest of your staff too).
In this particular case, it is a very small island with a lot less ability to get sources than some other stories as a result of that.
To start talking about it being a conspiracy that things are not published immediately is not how the media works. It's a lot less common than it used to be due to social media but it does still happen in a small number of cases.
It's possible the tragic discovery was today, but I also would not be surprised to learn it was yesterday. Both are viable.
