This an article from the Guardian about the killing of two journalists and a third woman outside a restaurant in Imatra, Finland. Although they admit that the killer is in custody, used a RIFLE to shoot them, and that they haven't established a motive...they claim it is "what appears to be a random shooting". I don't know how a group of people killed in front of a public place by a man with a hunting rifle can logically be assumed to be random, but I guess I'm a fake news kinda guy. Nowhere does the article confirm that the reporters were investigating child sex trafficking or that the meeting was about it.

So then there's this:

I don't know this site, nor does it look particularly professional or serious to me. However, it does claim that the journalists were looking into a child sex trafficking ring and were meeting the third woman to interview her about it. Its apparent citation goes to some sputniknews website, and while I do reject the "fake news" bullshit, I also know that Russia pumps out propaganda better than they pump out murdered journalists themselves. There are plenty more links in there but the ones I'm looking at merely back up his contextual history of child trafficking investigations, and none of it directly backs up the assertion that these journalists were looking into it. Nonetheless, if there's any possibility that these journalists WERE looking into child trafficking, the timing is extremely significant and it needs to be looked into.

Victims:

Imatra city council chair, Tiina Wilen-Jappinen

Finnish reporters Katri Ikävalko and Anne Vihavainen
