Let's not forget Courtney's first husband and what he says she did.
James Moreland, Courtney's first husband who was also a singer (The Leaving Train) had this to say about her:
"She definitely has an evil side. She once tried to burn my bed when I was sleeping. A fire started and I woke up in shock. It’s impossible to figure out Courtney’s motives. Her disdain was powerful, and she came off as a spoiled little snot… Courtney is a violent person who, even in the midst of our anonymous, crummy, poverty-stricken little marriage, threatened to have me beaten up for two hundred dollars when I didn’t do what she wanted. I was so scared of her I caved in immediately."
Trying to burn her husband. Murderous wife: check.
Paying someone to cause her husband bodily harm: check.
This is, sadly, the tip of the iceberg when it comes to Courtney's personality-disordered behavior.
I believe she had Kurt killed.
