Mo moved to West Palm Beach in 1948 where he remained the rest of his life. He was a graduate of Palm Beach High School and excelled in sports. In 1967, he started Mustaine Electric Company with his wife, Linda, and their business flourished until they retired in 1997.
His kindness, humor, and intelligence won him many friends; some friendships lasting 70 years. He was warm and generous with his family, friends, associates, and sometimes strangers.
Mo was predeceased by his wife, Linda Brown Mustaine, and his son, Michael K. Mustaine. He is survived by his sister, Candace Hinson, his siblings by marriage, Charles (Judy) Brown, Eleanor (Larry) Emma, Clara (Stanley) Harrell, and his longtime partner, Linda North.
Funeral arrangements will be made with Dorsey E. Earl Smith Funeral Home and Private interment will come at a later date.
