It has now been almost two years since Galleon Group co-founder Raj Rajaratnam was sentenced to 11 years in prison following his conviction on 14 counts of conspiracy and securities fraud. The Federal Bureau of Prisons assigned Rajaratnam to the Federal Medical Center Devens in Ayer, Mass., a facility about 40 miles west of Boston where inmates with serious kidney problems are often sent. At Rajaratnam’s sentencing hearing, the judge noted that Rajaratnam has “severe health problems, including diabetes that could lead to eventual kidney failure,” DealBook reported.
