What happened
A gunman killed ten people at a vocational college in Kauhajoki in 2008 before fatally shooting himself.
The investigation
Police investigated his online activity and a prior interview with officers that had occurred shortly before the shooting because of videos displaying a firearm.
What the courts or investigators concluded
The perpetrator died, so there was no criminal trial, but official reviews examined whether intervention before the attack could have prevented it.
Why the case remains significant
Coming less than a year after Jokela, the attack led to major national debate about firearm policy, threat assessment and police decision-making.
