Well, I really have no sympathy for this guy considering what he did. But he was the last person put to death by electrocution in Florida, so someone was able to make a case out of it.
He got what he deserved, and if it hurt, well...I'm sure it was no picnic for the woman he beat so bad she couldn't be recognized either. Not to mention her two kids and unborn child. Or the husband whose whole family was taken from him.
