Later in his life, he lost his insulation as he became less needed. He didn't just wake up and murder. But he was OJ. Something that was his was taken. He decided if he couldn't have her, nobody would have her. But he had been a thug his whole life.
Hate to admit, but I found If I Did It
at the Dollar Tree and picked it up (all proceeds go to the Goldmans and Browns) and read it. She was getting to be a pain in his ass: divorced him, but stalked him,and every time he got a new girl, she started harassing them and trying to split them up. Then she'd do shite like say, "I love you and we should get back together." He'd fall for it, then find her banging so other dude. With the kids, there was no way for him to be rid of her, save killing her. I think when he stopped by the house and found Goldman knocking the bottom out of it, he went nuts.
In that book, he's pretty much admitting to the murder, so I don't see why he would be lying about it.
