Father kills mother: post-traumatic stress disorder in the children.

Results of a study of over 100 children whose father killed their mother have been summarized and principles for practice have been formulated. All children orphaned by the death of one parent at the other's hands should be seen as soon as possible in a child psychiatry department and assessed. An immediate crisis intervention will probably be needed if they witnessed the killing to prevent PTSD. Bereavement counselling will be helpful in most cases. The caretakers will need support and help with their own mourning. Placement, access and custody, compensation, seeing the body, attending the funeral and dealing with family conflict will all need consideration. Long-term follow-up and further research are recommended.
