Libel case against Frederick Kempe In April 1990, Krupnick filed criminal libel charges in Panama against
Frederick Kempe, then the chief diplomatic correspondent for
The Wall Street Journal, following the publication of Kempe's book ''Divorcing the Dictator: America's Bungled Affair with Noriega''. Kempe was served with a summons while signing books at the Pavo Real restaurant in Panama City and was initially banned from leaving the country. The travel ban was lifted three days later after Kempe presented documentation about Krupnick from U.S. government sources. Under Panamanian libel law at the time, a writer had to accuse someone in print of committing a crime to be indicted.
Money laundering investigation Krupnick was named in a prominent Miami money-laundering case in 1994. According to reports, a database search by the
St. Petersburg Times turned up more than a dozen newspaper articles linking him to money-laundering investigations in the United States. ==Business activities==
