Onetime mob boss John Gotti ’s reality TV star grandson reported to federal prison after trying to stave off his sentence on fraud charges by saying he was going to donate a kidney to his ailing mother, Victoria Gotti. The Federal Bureau of Prisons confirmed Tuesday that Carmine Agnello began his 15-month prison term the previous day at the Federal Correctional Institution Fairton in southern New Jersey. Agnello’s lawyers said in court filings that Victoria Gotti, the daughter of the former head of New York’s Gambino crime family, suffers from chronic kidney disease.
