They got into a fight and he poisoned her

Old Hollywood Blind:

This actress was probably B list back in the day but she married into an A++ list Hollywood family.

Traces of that A list family are everywhere still today throughout Beverly Hills and portions of their life are tour stops for the buses.

Anyway, this actress caught her husband cheating on her for the millionth time and already had a life threatening STD she caught from him.

They got into a fight and he poisoned her.

He paid off police and walked away with nothing but his infected peen and a new girlfriend a few days later.
