Both gunmen had taken photographs of themselves in similar poses , and both exchanged videos related to school shootings on YouTube and Finnish social networking site IRC-Galleria . In March 2009 , Police ruled out contact with Pekka-Eric Auvinen , and said that he had committed his crimes alone : 200 people were interviewed during the investigation , none of whom said they knew of Saari 's plans
