" With the arrest and conviction of Gotti and various Gambino family members in 1992, Gigante was recognized as the most powerful crime boss in the United States. For about 30 years, Gigante feigned insanity in an effort to throw law enforcement off his trail. Dubbed "The Oddfather" and "The Enigma in the Bathrobe" by the media, Gigante often wandered the streets of Greenwich Village in his bathrobe and slippers, mumbling incoherently to himself. He was indicted on federal racketeering charges in 1990, but was determined to be mentally unfit to stand trial. In 1997, he was tried and convicted of racketeering and conspiracy, and sentenced to 12 years in prison. Facing obstruction of justice charges in 2003, he pleaded guilty and admitted that his supposed insanity was an elaborate effort to avoid prosecution,"
