The document said the arrest was for drunkenness while Kuchel had been in the midst of a sex act. Capell was indicted for the libel, along with Norman H. Krause, a bar owner and ex-Los Angeles policeman, who in 1950 did arrest two people who worked in Kuchel's office for drunkenness — Jack Clemmons, a Los Angeles police sergeant until his resignation two weeks before his arrest; and John F. Fergus, a public relations man for Eversharp, Inc., who was charged in 1947 with possession of a concealed weapon and given a suspended sentence.
