re: American Murder: Watts family homicides

my wife and i watched it Friday night. No excuses for what he did. Even my wife commented how much she put her life on social media. I do think the indecent with the grandparent and a cookie with a food allergy was taken way too far; was it an honest mistake? But i did have two points/questions.

At the beginning she said she worked her tail off and built he first house at 25 alone, what in the hell was she doing, or was it a first time homeowner's special?

The girlfriend to me looked a lot lot his wife. but the police department kept on referring to her as his hot new girlfriend. I guess she was not as crazy as the wife?
