There was a theory he was covering for his oldest son. Jason, that I read about years ago. Is that what you’re referring to in calling him an Incredible father’ @misszebra? Not sure if it was ever debunked.
TBH there were a lot of disturbing ‘coincidences’ involving Jason from that night if what I read is true - he was annoyed with Nicole, carried knives as a chef, had a temper problem that he was medicated for, wore hats similar to the one found at the scene and had a dog the same colour as the dog hairs on it, called OJ that night, was lawyered up before being interviewed. Theory is the LAPD would not admit they may have been wrong about OJ.
Not defending the man as he was at the very least an abusive, violent scumbag as proven by Nicole’s hospital admission, his first wife claimed he was violent to her too, and the book was in horrendous poor taste but if true about his son, it could be credible.
