So called extended suicides are a parents murder of his or hers own children, and sometimes also of the other parent, followed by the perpetrators suicide. Our investigation documents that these homicides has decreased in number in Denmark and that the perpetrators are now predominantly the fathers. In an earlier investigation (Homicide in Denmark 1946-70, doctoral thesis by Hart-Hansen JP) the predominant type of extended suicide was committed with carbon monoxide from household gas, but today the preferred homicide methods are much more violent. The reason for the dramatic fall in the number of extended suicides in Denmark can not be deduced from our study, but it is possible that it is related to changing social conditions for and a changed view on unmarried mothers. The motive for these killings was originally stated to be altruistic (the child should not live without the mother), but is now more often related to revenge (if the mother do not want to live with me, the children and she must die).
