What happened
An explosive device detonated at the Myyrmanni shopping center in Vantaa in 2002, killing seven people including the young man who carried the bomb.
The investigation
Police examined his computer activity, chemical purchases and online discussions to determine how the device had been constructed and whether others had participated.
What the courts or investigators concluded
Investigators concluded the bomber acted on his own, although uncertainty remained over whether detonation at that exact moment was intentional.
Why the case remains significant
The case was an early warning about the availability of technical bomb-making information online and the difficulty of interpreting intent after the perpetrator dies at the scene.
