After his serving in the Navy, Fleming worked at local newspapers and eventually worked his way up to becoming a reporter for
The Atlanta Constitution Magazine. In 1961, having worked as a stringer for
Newsweek for a number of months, he was hired by the magazine as a permanent correspondent in their Atlanta Bureau when
Bill Emerson, formerly Atlanta Bureau Chief, was promoted. During his career as a journalist, Fleming risked his life covering
James Meredith's entry into the
University of Mississippi and also in 1964 when he covered
the murder of three civil rights activists (
James Chaney,
Andrew Goodman and
Michael Schwerner) in Philadelphia, Mississippi. After a brief stint at the Houston Bureau, Fleming was promoted to chief of
Newsweek's Los Angeles Bureau. Whilst in this post, Fleming not only covered the
Watts riots of 1965 but was also severely beaten during a later flare-up of tension in LA's southern black neighborhood in 1966. In 1972 two men used counterfeit 20-dollar bills printed with
D. B. Cooper serial numbers to swindle $30,000 from Karl Fleming who was then working for Newsweek in exchange for an interview with a man they falsely claimed was the hijacker. ==Personal life==
