A man who disappeared and was presumed dead by his family was found four years later living a different life with a different name. The author interviewed and received correspondence from several sources related to the incident. While living under an alias, the man was recognized, but did not remember anything of his previous life or family. Upon awakening to his previous identity following a period of stress, headaches, and a nap, the man recognized his family members, but remembered nothing of his alias. A physician provides a theory that the alternate personality may be related to a blood clot.
