Bernard Madoff was transferred today from Manhattan’s Metropolitan Correctional Center to a prison in Butner, NC, to serve out his 150-year sentence, sources tell CNBC. Madoff’s attorney had requested that the 71-year-old convicted Ponzi schemer do his time at Otisville in upstate New York. The prison system tries to place inmates within 500 miles of family; the Butner facility is just within that distance from New York. (More Bernard Madoff stories.)
