I recall SB saying that she awoke at around 11 AM but she did not get out of bed until around 1 PM.
I don't remember clearly so that's quite possible. I would think if she was awake, she'd want to get out of bed and go smoke a cigarette before 1:00, but who knows. I don't think we'll ever know the truth about what happened in that house in the 24 hours prior to the police arriving.
