What happened
A gunman fired from a rooftop into people in central Hyvinkää in 2012, killing two and injuring several others.
The investigation
Police rapidly secured the area, identified Eero Hiltunen and arrested him after the attack. The investigation reconstructed his access to firearms and actions before the shooting.
What the courts or investigators concluded
Hiltunen was convicted of two murders and multiple attempted murders and received a life sentence.
Why the case remains significant
The case added to Finland’s continuing policy debate about access to guns and how apparently abrupt mass violence can be prevented.
