Remember that 60/40 cannot account for the large mass of unsolved killings of men.
Notice all those guys who came back from Iraq who got killed by their wives/partners?
And also note women are far more likely to hire someone to kill their partner and the victim (if anyone ever finds out) is more likely to go in the “multiple killer” category, which may skew numbers.
And if we catch people all the time trying to hire someone to kill their husband, then it only makes sense that we’re catching the most impatient or incompetent. There are likely a number of men who’ve been killed for other reasons that were actually done in by their wife’s request.
There was even a case that appeared on Dr. Baden’s show on HBO (Autopsy) where his further research proved the kid’s father was murdered by the wife.
As pointed out in the article that brought some of those numbers to light, men also often kill themselves after killing their partner and often the case involves tormented emotional outbursts and rage, whereas women poison and try to have their husbands killed and are far more cold about it and are more likely motivated by financial gain (insurance,etc.)
I do believe there is an inherant problem with attributing the deaths of men properly. I’m just not sure how to quantify that segment of the deaths.
