If you're talking about last nights episode, it wouldn't make any sense for it to be the wife though. If she did it then she could have just let it go and no one would have been the wiser. She's the one who asked for an investigation.
I watched half of the first season of LA. I stopped watching because, as you say, it just isn't the same. I'm 33, so I don't exactly consider myself "old" but I feel that LA is aimed at a younger audience and the original is aimed at a little older audience.Eh. I haven't watched L.A., don't plan to watch the new one either. Just isn't the same.
