Warren Leslie, who in 1964 raised hackles in Dallas, his adopted hometown, when he contended in a book that a climate of right-wing extremism had primed the city to become the scene of a national tragedy — the assassination of President John F. Kennedy — died on July 6 at his home in Chicago. He was 84.
Mr. Leslie left Dallas soon after “Dallas Public and Private” was published and returned to New York, where he worked for Revlon and started his own public relations firm while helping to write scripts for the soap opera THE SECRET STORM, whose head writer for a time was his sister, the actress and writer Bethel Leslie.
