It's not how many men murder one, two, or three spouses as that would be a small percentage of the population. The question is how manyy men who have already killed 2 spouses go on to kill a third spouse as well. I suspect that is a much higher probability and this woman is quite at risk if he is indeed guilty of the prior 2 murders.
