Another dreadful example came to court just the other day: a man killed his girlfriend of two year's standing, leaving a three year old boy without a mother.
The questions I asked before seem just as pertinent now as then:
Is there a disproportionate frequency of abuse and murder of women and children by men living with women who have children by previous relationships? If so, is there a causative link between such patterns of relationship and abuse, or is it merely a co-factor of other determinants (eg chaotic life style, educational levels, deprivation, poverty)?
But I have yet to see any research, or even commentary, on this. It simply doesn't fit with the desired narrative of our modern society.
