Music mogul? He was a lawyer and businessman, most famous for being part of OJ Simpson's defense team.
She was 22 when she married him, which isn't that young ( although they'd been dating since she was 17/18)
I wondered if that was him. He and his then wife (gf ?) used to socialise with oj and nicole ,I think. I've a vague recollection of seeing pics of them all in a book on nicole's murder.Or am I misremembering ?
