Domestic abuse: Killers 'follow eight-stage pattern', study says
''The eight steps she discovered in almost all of the 372 killings she studied were:
- A pre-relationship history of stalking or abuse by the perpetrator
- The romance developing quickly into a serious relationship
- The relationship becoming dominated by coercive control
- A trigger to threaten the perpetrator's control - for example, the relationship ends or the perpetrator gets into financial difficulty
- Escalation - an increase in the intensity or frequency of the partner's control tactics, such as by stalking or threatening suicide
- The perpetrator has a change in thinking - choosing to move on, either through revenge or by homicide
- Planning - the perpetrator might buy weapons or seek opportunities to get the victim alone
- Homicide - the perpetrator kills his or her partner, and possibly hurts others such as the victim's children
The only instance where a stage in the model was not followed was when men did not meet stage one - but this was normally because they had not had a relationship before, she said.
"We've been relying on the 'crime of passion, spontaneous red-mist' explanation [of killing] forever - and it's just not true," Dr Monckton Smith told the BBC.
"If you start looking at all these cases, there's planning, determination, there's always coercive control."
