Bettye Whitaker, 64, vanished from Novato, California, after leaving Novato Community Hospital against medical advice on March 4, 1981. At the time she was using the alias Lana Lee. Her vehicle was never found and there has been no confirmed sighting since she walked away from the hospital.

Bettye stood 5 feet 2 inches and weighed about 160 pounds, with gray or partially gray hair and blue eyes. She wore a gold bracelet and a rosary when she left and had IV scars. Investigators have been unable to locate any family members or obtain DNA, dental records, or photographs, which has hampered identification efforts.

Anyone who knew Bettye, knew someone who used the name Lana Lee, or has information about patients who left Novato Community Hospital around March 4, 1981, is asked to come forward.
