He's mentioned it several times, the first in response to a person feeling guilty because they were dogsitting and the dog got out and could have been hurt. And HS talked about ~~forgiveness~~ and gave a counter example of the time his girlfriend had just scored some drugs, probably been raped, and they "had sex" (which he described in lavish detail while also describing how out of it and upset she was, so could she even give consent?) and then he decided she need to die because the world was too horrible so he tried to kill both of them with gas. A neighbor smelled the gas and called the cops. They arrived and found two drugged out folks, one of them white and affluent and male with connected family members, and decided it was a consensual murder suicide. No charges were ever filed. HS, remember, related this story to a DOG possibly getting HURT through ACCIDENT. While in AA, he tried to look up this woman to apologize and she/her family refused to speak to him, so of course he goes around telling her story.
