Here is what happened
She was drunk. She fought with her husband. She got violent and tripped and fell off the boat. He was so upset he didn't realize she had fallen into the water and when he realized she did it was too late because the boat caption was too busy getting stones and Mr. Wagner was distraught.
Why should he have to suffer because of her drunken stupor?
The trolls are playing both sides. Natalie Wood is very famous and not forgotten all these years after she accidentally went into the drink on Catalina. Saying she is forgotten is a lie.
Her husband Robert John Wagner is very famous too. He is a living legend and should be treated with respect and reverence and so should she but not at the expenses of the truth.
