Data collection in Finland took place in the context of the Finnish Homicide Monitoring System (FHMS) designed by the National Research Institute of Legal Policy and the Research Unit of the Police College, and has been augmented by full text searches in national news agency and newspapers. Between 1996 and 2006, a total of 108 HS events with 135 victims with have been recorded. 36 cases are included in which the suicide of the perpetrator was not successful. Homicide-Suicide related results based on a part of this database have previously been published by Kivivouri and Lehti (2003). One of the striking results was that perpetrators of homicde-suicide are on average of higher social status compared to other homicide offenders.
A more general overview of the Finnish homicide situation and the FHMS has been recently made available in English (Kivivuori & Lehti & Aaltonen 2007).
