The patient is a 42-year-old white male who was brought to the emergency room by the police. He was involved in an argument and fight at the diner where he is employed. When the police arrived and began to question the patient, he gave his name as Burt Tate, but had no identification. Burt had drifted into town several weeks earlier and begun working as a short-order cook at the diner. He could not recall where he had worked or lived before his arrival in this town. There were no charges against him, but the police convinced him to come to the emergency room for an examination.
