I don't think his defense is going to fly. It doesn't matter if he was high on cough medicine. He voluntarily took it, he took it recreationally and not because he had a cold or was sick, and it's no different then a DUI. He is still culpable, his wife is still dead, and he did it. He doesn't get a free pass in my eyes.
Also, maybe after the first divorce, if he lost assets in that divorce, he might not have wanted to lose anything else with a second divorce. Much like Drew Peterson. Either that or he did have one divorce, if he wanted to pursue a clergy job, that divorce was going to be a hurdle. Two? Now way.
IMO, he either had a life insurance policy to collect on, or had a girlfriend and wife was in the way, or he's gay. Pick one.
