[3] Ibrahim Shkupolli, Albanian born in Yugoslavia but had lived in Finland for many years, shot three men and one woman who all worked at Prisma.

[6] The perpetrator, identified as 43-year-old Kosovar Albanian Ibrahim Shkupolli, was seen walking into another shop where he disappeared, sparking a major manhunt which involved police helicopters.

[7] His apartment was completely empty except for a mattress, a framed photo of his ex-girlfriend, 14 fully loaded magazines for his gun, and a bag containing additional 273 cartridges.

The firearm used was a Czechoslovak-made 9mm CZ 75 pistol, manufactured in 1984 and was originally sold in Norway where the gun went missing due to an unsolved burglary case in 1990.

[10] Ibrahim Shkupolli (1966 – 31 December 2009) was born in Mitrovica, Kosovo, worked as a grocer,[11][12] and had resided illegally in Finland since 1990.

Shkupolli had been married to a Kosovar Albanian woman with whom he had three children[14] but maintained an on-off relationship with his Finnish girlfriend both before and after the marriage.

[6][15] In both of his former and present municipalities of residence, Mikkeli and Espoo, restraining orders had been imposed on him after his girlfriend filed charges about his behavior and numerous threats, including one to kill her.
