The 8 Stages of Domestic Homicide
As part of our ongoing work on the prevention of gender based violence, we were pleased, that in February of this year, Rosie Lewis from the University of Hertfordshire hosted a webinar for the Foundation on Identifying Stalking and The 8 Stages of Domestic Homicide (Homicide Timeline).
The Homicide Timeline developed by Dr. Jane Monckton Smith, is set out below and maps the progression of abusive, coercive, and controlling relationships towards murder.
This framework is designed to help professionals and the public identify high-risk situations and intervene before a homicide occurs, shifting the view from "crimes of passion" to a predictable, planned process.
Stage 1: Pre-relationship
History The perpetrator has a history of stalking or abuse, often showing a pattern of controlling behaviour with previous partners.
Stage 2: Relationship Development (The "Whirlwind")
The relationship moves very quickly from the initial meeting to becoming serious and intense.
Stage 3: Coercive Control
The relationship is dominated by the perpetrator, who controls the victim's life and behaviour.
Stage 4: Trigger
An event threatens the perpetrator's control, such as a planned separation, financial issues, or illness.
Stage 5: Escalation
Controlling behaviour increases in intensity or frequency, including stalking, threats of suicide, or increased violence.
Stage 6: Change in Thinking
The perpetrator changes their mindset, deciding that the situation is unforgivable, often feeling rejected, humiliated, or vengeful.
Stage 7: Planning
The perpetrator actively prepares for homicide, such as buying a weapon, stalking the victim, or establishing a timeline.
Stage 8: Homicide
The homicide is committed, which may include the suicide of the perpetrator.
At the Foundation, we believe that building healthy relationships starts with education and at an early age. We have developed resources for Primary and Secondary students which can be accessed here -
