In the absence of further reporting, it's obviously impossible to say what happened. As always, there are a couple of possibilities, but in the current news media climate it's not very likely that there will be a follow-up article.

There will be an inquest, at which all known facts will be revealed, and journalists or campaigners sometimes go to these. Inquests often take place long after a crash, and if you're not an interested party, you have to monitor the relevant coroner's office's web-site (and know the victim's name).
