"Latest news is Ludwig gave a statement to police that he intended to kill both of them. He took the weapons to their house specifically. I think it'd be pretty tough to avoid seeking the death penalty for two premeditated murders."
Ludwig and the girl ought to get the death penalty. At 14 years old she is obviously mature enough to decide to help kill her parents and willingly run away to get married with the killer. I say fry her too.
She at least needs to go to jail as an accessory after the fact (if not before).
I didn't want to bring up "death penalty" during my first visit to this site... without finding out which way the wind blows... but, now that it has been addressed.. I sure can't see any reason to keep him alive, other than I am not Lachesis.
