He drugged the femaile patients so they wouldn't know what was going on as far as I know. And there never was a murder trial for him as such because he admitted his guilt, so it was really just a sentencing.

At the end of the day, Hazel Buchanan's husband, as she was then, well he was a policeman, he had a gun for personal protection. All she had to do was say this man is coming to kill you and it would've been taken very seriously by the police and if she hadn't drugged Trevor Buchanan then he would've been able to defend himself.
And another thing that didn't come out in the trial is the reason his marriage to Kyle fell apart. I know the reason, and it is yet another thread to the sorry tale.
