Background: Following a meeting with then Minister for Justice Flanagan and Mary Coll and her daughter Jacqueline in February 2019, it was announced that arrangements were being put in place by the Department of Justice for a study to be conducted in relation to measures to prevent and address matters relating to the unlawful deaths of family members. The study team met with many of the families of victims of Familicide and Domestic Homicide (including the Coll family). In addition, the study team met with relevant State Departments and Agencies and other relevant organisations. The study team received a number of submissions following a public call in June 2019. The study team also offered interested parties an opportunity to meet with members of the study team to tell their story.
