Mr. David French:

The research was done by Professor Dora Black in the UK. It is summarised in a book, When Father Kills Mother. The authors are academics and the book is the accessible version of the research. It looked across a 20-year timespan so it covers a large cohort. There are further references from that but it is the leading part. In answer to the Deputy's last question, as far as I can see, as of 2019 this had not been incorporated into the practices in this jurisdiction. When Father Kills Mother is a blunt title. The book is about dealing with the children and talks to children in these cases. It looks at placements and how they worked out for the children's mental health and best interest going forward. It is solid research covering a large sample size. There are many other researchers, such as Professor Eva Alisic in Melbourne and a chap in Scotland, Professor John Devaney. In social work, and this specific post-homicide case, it has been looked at by many people. In the UK, there are approximately two killings of women and girls by partners or ex-partners per week. These are mostly women of child-bearing age so there are many children to study. There is a well-known set of dynamics and clear patterns.

There are journals devoted to this space. It is a big area and there has been a lot of research. When Father Kills Mother is the starting point as a book, but I reference several others in my submission.
