"So many different mental disorders," Dr. Alison McInnes
said Tuesday as she
led a jury through the branches of men and women, the flashes of color, that yielded the man convicted last week of murdering three tourists in February 1999. McInnes, an assistant professor of psychiatry and human genetics at the Mount Sinai School of Medicine in New York, pointed to Stayner's gene pool and environment. She

thought the world was ending, that he
was receiving messages from television and others commanding him to "do something that he
didn't want to do," McInnes
