I wouldn't want to try to defend this man if the D.A.'s office charges him for killing the woman. From what's been reported, several things would tend to work against him.
The two intruders, even though they roughed him up enough to break his collarbone, were both unarmed.
They let the homeowner get up and go to another room, where he got the gun. That tends to undercut the claim that he had good reason to fear he was in danger of death or great physical harm from them. He might just have locked himself away from them, or left the house, or phoned for help, and he could have pocketed the gun in the meantime, just in case they tried to attack him further.
He came back with the gun and shot at the two, even though by then they seemed to have turned away from him to search for things to steal.
He shot the woman in an alley, even though she had clearly submitted to him by pleading for him not to shoot.
He ignored her plea and shot her twice in the back.
He then dragged the woman back onto his property. That suggests he knew he had not shot her to defend himself but was trying to make it look more like he had.
If he is charged, the prosecution might claim he did not kill the woman to protect himself or anyone else from the threat of death or great bodily harm at her hands. They might argue that the real reason was that he knew, or thought he did, that the two had broken in on him before, and that was trying to make sure--by killing them both--that they could never do it again. But if that were reason enough, it would be all right to kill anyone who had committed a crime against you to keep him from ever doing it again, even is he had never put you at risk of death or serious injury.
According to CBS (linked above), "Police said both burglars were unarmed and that Greer told officers the same couple had robbed him at least twice previously."
This is why it's important to reserve judgment until all the facts are in. Both CBS and CNN are legit sources, but their info varies.
I just can remember the old adage about shooting a burglar in your house who is blown out the window and dragging him back inside to save your arse. With that said, I still believe shooting her down an alley is going to be a high hurdle. But it only my opinion,which at this point is about as misguided as any of the other legal experts here.
