More people killed as a result of the Canadian train crash, but it is hardly mentioned.
Because it wasn’t here. Americans have a long history of not being terribly interested in foreign news, and the media feeds that by not reporting it unless nothing else is happening. And when they do report it they’re always trying to bring it here conceptually, you’ll get things like “40 dead including 3 Americans” to try to make it “American” news. It’s not a good habit, but remember they’re actual job is to sell commercials, not to inform, so they need to feed us “news” we find interesting otherwise we change the channel.
