(AP Photo/CBS, File) (Newser) – Bernie Madoff's son Andrew died this morning of cancer at age 48, his lawyer tells CNBC. "Andrew Madoff has lost his courageous battle against mantle cell lymphoma," the lawyer says, per Reuters. "He died peacefully at Memorial Sloan Kettering Cancer Center on September 3, 2014, surrounded by his loving family." Andrew Madoff was Bernie's only surviving son after his brother, Mark, committed suicide in 2010. The two said they knew nothing of their father's Ponzi scheme; neither ever faced criminal charges in the case, Reuters notes.
