Myyrmanni bombing
Summary
The Myyrmanni bombing took place on October 11, 2002, in Myyrmäki, Vantaa, Finland, in Greater Helsinki, at the Myyrmanni shopping mall. A bomb was hidden in a backpack, which exploded in the central square of the shopping center on top of a metal waste container, located in the center of the square, at 19:36. Five people were instantly killed, including the bomber. The waste container was shattered, and fragments of the structure increased the amount of shrapnel and the devastation. The explosion ruined 400 m2 of the shopping center, carved a 10-cm deep crater in the floor where the waste container had stood and blew the glass dome over the square up and outwards from the mall. In total seven died, including two teenagers and a 7-year-old. 159 were injured, including 10 children. 66 victims required hospitalization with the remainder treated and released at the scene. The bombing took place during the pre-weekend shopping surge late on a Friday afternoon, with 1,000–2,000 people in the shopping center, including many children who had come to see a clown performance.
The bomb carrier was Petri Erkki Tapio Gerdt (April 17, 1983 – October 11, 2002), who was killed in the explosion. He was a quiet 19-year-old chemical engineering student at EVTEK (Espoo-Vantaa Institute of Technology) and a hobbyist bomb-maker. Gerdt was known to have had no notable friends. He played basketball and had no prior criminal record. He was also an active member of Kotikemia (lit. "home chemistry"), an online forum for amateur chemists. The moderator of Kotikemia was acquitted of responsibility in court. The explosive device was likely constructed in Gerdt's apartment. It was a 1.5 liter plastic bottle that contained ammonium nitrate and nitromethane with shotgun pellets and weighed about . Investigations revealed that some kind of a timer was also used. Kotikemia was shut down by the authorities following the bombing.
The Finnish National Bureau of Investigation investigated the event as six accounts of murder, one account of aggravated criminal mischief and one account of an explosives offence.
