Suggest a few people in this thread have a read of what he was actually convicted of. Second degree murder doesn't require an intent to kill. Its all summarised in the jury's instructions which are only a few pages long here.
Second-degree murder does require that, but the charge is explicitly Second-degree unintentional murder.
