(dpa) - A Finnish high school student who in November killed eight people in a school shooting acted alone, police said Thursday as parts of their investigation were being published.
Investigators concluded that 18-year-old Pekka Eric Auvinen began to plan the massacre in March 2007, and joined a shooting club in August.
In mid-October he applied for a gun licence and in early November acquired the gun and ammunition used in the November 7 rampage, according to the report.
According to a journal Auvinen kept, he anticipated that he would die in connection with the shooting and he called the planned massacre "Main Strike."
While he apparently did not disclose his plans to anyone, he was engaged in discussions via e-mail on violence with some 10 people, of which half lived in Finland.
"We have clarified that no one inspired him to act," detective Tero Haapala, who led the probe, told the Hufvudstadsbladet newspaper.
The victims, including the school principal and six other students, were selected randomly. The probe also suggested more than 50 shots were fired.
Auvinen was found with 327 rounds of ammunition after turning the gun on himself at the school complex in Jokela, 60 kilometres north of Helsinki.
Police Thursday released 600 pages of the 2,600 page investigation, saying the bulk of the report would be sealed.
The shooting triggered a series of threats against schools in Finland and its Nordic neighbours.
