Maggie Peterson's niece Amy Royer confirmed in a statement on Facebook page that
"She passed peacefully in her sleep with her family present. Maggie's health took a turn for the worse after the death of her husband Gus [Mancuso, revered Las Vegas musician] and we are relieved that we were able to move her home to be close to family for her last days, We will be planning a private service for Maggie in the next few weeks."
