FWIW, I don't recall which legal document I saw it on, but I believe it was a statement by LE that one of NC's friends had advised LE that first day, that Brad and Nancy had been arguing all day on the 11th about money and Nancy painting. This was not a continuation of the disagreement they had been having all week long, which was over the condition of the home when Nancy and the girls returned from vacation the weekend prior.
IMHO, Nancy would NOT have told him to 'wait' to give her the money. Brad was just making EXCUSES on the video to fit his 'staging' of the crime.
ALSO, FWIW, Brad only went to the BBQ for ONE HOUR. He left work around 6, stopped and picked up beer for himself, got to the BBQ around 7 and went home with the girls around 8.
I still believe Brad went home because he was PO'd at Nancy for correcting him in front of HER friends about 'listening' to what their little girl was trying to say she wanted. He was embarrassed because NO ONE corrected him, EVER, either alone or especially in front of others.
He may not have preplanned the murder days and weeks in advance, but it was most likely on his mind and by the time she returned later that evening, he was ready for the kill.
Brad has made it VERY CLEAR that all of their marital problems were because of Nancy. Nancy over-spent, over-drank, wouldn't forgive him for having an affair although she'd had one of her own (with no sex), withheld sex, wanted all hi$ money, wanted the best of everything, was NEVER happy with anything he did and she was ALWAYS punishing him or mad at him. Poor little Brad, all he tried to do was make her happy, yet she constantly punished him.
I can't wait for the DA to play Brad's depos to a jury when he talks about his wife and how she mistreated him. Of course, that will be after they've heard from everyone else, INCLUDING Nancy (on tape).
JMHO
