One of convicted US fraudster Bernard Madoff’s sons has committed suicide in his New York apartment, a family lawyer has said, BBC reported. Mark Madoff, 46, was found hanged in Manhattan on the second anniversary of his father’s arrest. Mark Madoff and his brother Andrew were both being investigated in the case but had not been charged. Bernard Madoff admitted last year defrauding thousands of investors through a USD 65 bln Ponzi scheme. The scheme pays out using new investors’ money rather than from any profits. Bernard Madoff, 72, is serving a 150-year prison term.
