John Rees was contracted to help covertly install a microphone in Hawkins' office, and have it connected to a secure "broadcast loop line" sent to Schecter's personal home in Shaker Heights, where it was connected to an amplifier. The monitoring of Hawkins' office itself lasted between October 23 and November 9, 1972, when Eaton ordered the removal of the line after conferring with Perkins' law firm partner. The microphone was later discovered by a telephone company employee doing regular maintenance work at the station, who promptly notified the Federal Bureau of Investigation (FBI). Schecter and Rees pleaded guilty in federal court to the charges of bugging Hawkins' office on December 11, 1973; both were fined $500, placed on one-year probation, and fired from their respective positions. Indictments were then returned against Silverman and Perkins on March 1974, both faced one count of illegally wiretapping and aiding and abetting; the Department of Justice agreed to reduce the charges to a misdemeanor. Both plead "nolo contendere" to the misdemeanor charges that December; Silverman was fined $1,000, while Perkins was fined $2,000 and faced an investigation by the District of Columbia Bar for possible disbarment, this investigation was dismissed after the bar's disciplinary board could not find evidence of any outright ethical violations.
