The first wife of GL seems to have been driven to suicide by the suffering he caused her, definitely something preventable and as for the Serial killer theory, I wasn't really responding to that, more so,
a) thinking that if perhaps GL had been charged with domestic violence offences he would have lost his freedom before RH and CC had their lives taken
and,
b) wanting my fellow sleuths to view the diagram because it's informative and in Australia especially - where I and many other WS members reside - we have one of the highest numbers of women killed each year as a result of domestic violence.
(mainly from current or ex-partners although DV is not restricted to partners - fathers, sons etc also count as domestic perpetrators) so it's important to be informed about what the signs of DV are.
But you're enthusiasm is good and you mind is certainly a well-oiled machine
@5W's EDIT: women can be DV perpetrators too, although statistically it's usually men.
We can note the average size and strength difference between the two genders as the main reason DV is a male dominated crime but there are many other factors which contribute, the discussion of which is not appropriate on this forum.
