Yeps, all persons involved are Finnish, and the kid's been taken into the care of the social services while this pans out.
I'm guessing that over the weekend - it being a long bank holiday from Thursday through Monday - that the family of the shooter likely went up north to their mökki (as is tradition over the Easter break) to get things sorted and ready for when they move up full-time for the summer. If they're in an area with wildlife roaming, the gun is a necessary tool to protect the family from anything between wolves, bears, moose, wild deer, stags in heat, etc.
Gun ownership is very common, but most people don't bring their hardware home to the city - they usually secure it in the mökki all the time.
The school has been closed for a few days, they need to comb the scene I guess, I hope the kids get the counsel they need - which they will of course.
It's usually at this point that people start pointing fingers and suggesting we ban all guns. Stupid move, it puts people's lives at risk. The wilds are full of animals of all sorts, there's no way I'd hang around in bear country (just a couple of hundred miles north of where I sit) but even so, we've had bears and wolves wandering into towns not far from here, looting the bins in the wooden house districts (in the city it's much tighter: we have three bins beneath the sink unit: two are large and are for general waste and the smaller one's for bio). The garbage halls on the ground floor have massive steel doors and not even a mouse can get in. There are five or six types of waste collected from those: general, paper, bio, metals, glass, and cardboard.
But out in the suburbs, people have outside bins like you do at home: if the wildlife is having a tough season, then they'll eat anything they can find. They don't like people so it's not a good idea to approach any of them. Fire a shot into the air/ground first, then see if that scares them off. If not, shoot next to them as a warning. Then if they defy you, you have to shoot to bring it down, so a leg or in the arse. If they attack - kill them. There's no other options. You can't run from a bear or a wolf. Not even a moose if they're angry enough and have the kids with them.
Yeah - there'll be blood and hair flying over the next couple of days.
The funeral for the deceased child likely won't take place for some weeks yet.
The process of postmortem activities takes a while up here.
Damn, but the parents of the dead kid?
Fucking hell.
