On October 11th 2002, a 19-yearold man, Petri Gerdt, detonated a homemade bomb in the Myyrmanni Shopping Centre at Myyrmäki in the Helsinki area. Seven people died and over a hundred injured. On November 7, 2007 an 18 year old student, Pekka-Eric Auvinen, killed eight students, staff and faculty at Jokela high school close to Helsinki. Although the cases should not be simply compared, it seems that social rejection and virtually reinforced narcissism played some part in both. The offenders were relatively lonely in their face-to-face life. The lethal combination of narcissism, violent fantasies and social rejection also played a part in the Columbine high school shooting in the USA (Twenge & Campbell 2003)., In the Jokela case especially, Auvinen performed a violent identity-play through the net. He informed people of his actions on various Internet forums (IRC Galleria, YouTube and Rapidshare) and was clearly conscious of the media effects of his actions. In the aftermath of Jokela, several pupils tried to attract public attention by making false threats, leaving messages on Internet sites and forums. As of February 2008, there have been at least 70 cases in Finland, in 40 cities and 64 schools. Most of the offenders have been boys aged 14-15, but some offenders have been girls and olderboys (Puustinen 2008). This article analyses the above two case studies as well as other instances in Sweden and Norway as well. It argues that these cases display the vulnerability of Internet forums to misuse. The cases also call for a new understanding of youth today and should be interpreted as signs of social and cultural problems.
