I think links stories get updated pretty regularly now. That's pretty normal. As long as the header has time originally posted and timestamps for any updates, that's pretty standard for news in the 21st century.

For a story like this the initial post would be "Heavy police presence at address" then probably updated it was a shooting, then updated it was a fatal shooting, then updated with more detail after they get a more formal story/background info or whatever.

I wish media outlets would wait until there's a little more verifiable info to report before the first one, but people act like it's some kind of "Gotcha!" if another outlet has the link up earlier so the public ruins everything.
