R. Allen Stanford, the Texas financier accused of directing a $7 billion Ponzi scheme, complained that his jail cell often lacks light and air conditioning. For the past week, Stanford, who's in a cell in Conroe, Texas, with from eight to 10 other men, has endured heat and intermittent lack of power when outside temperatures reached 100 degrees Fahrenheit (38 Celsius) or more, his lawyer, Dick DeGuerin, said yesterday in a motion asking that his client be transferred to a downtown Houston jail.
