OK, everyone here knows I oppose the death penalty in all cases, including this one, right?
...there were mitigating factors that the jury were not informed about.
Which may not have been relevant to the jury in this case.
It depends on specific state law, but such mitigation is only rarely relevant to a defence. I only found
this cartoon today but it's already useful here.
In general for provocation to be a defence for a murder the murder needs to be committed in the heat of the passion invoked by that provocation, as judged by some hypothetical 'reasonable person' (in reality, a juror trying to pretend they are a rational person). In this case the murder was years after the fact, so a 'heat of the moment' case is hard to make. I'd say that the murder being premeditated, with the planning and execution of the crime taking place long beyond any temporary loss of reason, would destroy such a defence regardless.
A
justification defence is even harder to make, and pretty much demands that the harm being prevented is a) immediate, b) only prevented by the actions, and c) to prevent a harm greater than that caused by the actions. Given that the killing of an individual outside of extreme circumstances is always seen as a great harm, it's nearly impossible to justify killing someone under US law, outside immediate self defence or it's sometimes subverted cousins.
I'd actually guess that his being molested in the past would only be relevant in terms of sentencing, not guilt. Again, how this would come into it depends on the state and it may be that even then it isn't sufficient for mitigation. But certainly, given how the molestation was completely irrelevant to the question of his guilt, I would not expect the jury to be informed of it.
It's outside their need to know and may colour their ability to accurately judge the relevant points of law.
On the other hand,
Wikipedia suggests the jury called for the death penalty, but the cited article is in French. Anyone got another source on that? If that is the case then I'd guess it was the lack of the molestation being brought up that put him on death row, but that's very hard to appeal. Bringing the molestation up during trial
shouldn't have changed the finding of his guilt, but
may (depending on the jury, I'd say that is
would or at least
should) have changed his sentence.
I'd say a crystal clear case to commute the sentence, especially given the range of voices calling for such action.
