On the morning of her death, she called actress Jeanne Carmen, who told Vanity Fair, that Monroe sounded distressed.
“She said some woman had been calling all night, harassing her and calling her names,” Carmen said.
“The voice sounded familiar, but she couldn’t put a name to it. The anonymous caller had said words to the effect ‘Leave Bobby alone, you tramp. Leave Bobby alone.'”
Carmen also said that Monroe asked for sleeping pills and wine, but Carmen declined her request.
