Yeah. If they had evidence that could remotely point to KK it would have been their best defense.
This is very good for the state.
And @MassGuy is right. The I had a bad childhood is not an actual defense at all. Unless it supports total insanity at the time of the crime.
Instead, it goes to mitigation. And in the US it seems to me it actually doesn't work that often.
I read a book by a psychologist who studied kids charged with murdering their parents and his assessment was that in pretty much all the cases the kids had been subjected to intolerable and extreme abuse.
However, except for one kid who was able to walk slowly in front of the jury and show them the scars that crisscrossed his body, it didn't seem to result in a reduction in sentence even though in many cases the killings were practically self defense.
I think it's more likely to work with juveniles though and young women.
