It’s perhaps a little different than an american shooting a school.
In one, you’ve got lots of victims, too many for one person to remember, but only one name for the killer, so it’s more likely to stick.
In this case, I think people are going to remember the one victim. Similar to James Bulger.

Edit: As a footnote, I had a read through the James Bulger wikipedia page after I wrote, and I really wish I hadn’t.
