"Wizard of Oz" actress and former KTVU reporter Betty Ann Bruno has died, her family confirmed with Fox News Digital. She was 91.

"There's a lot I can say about my mom. … Growing up, she was certainly one of the most socially aware and caring … active people that I've certainly ever come across," Steve Bruno, Betty Ann's youngest son, said. 

Betty Ann's son revealed his mother's sudden death came as a "shock" since she was "very healthy." 

She tragically fell at the hospital after performing one of her Hawaiian dances. He noted that she was a passionate hula instructor and created the dance organization Hula Mai in Sonoma, California.
