A Sacramento beauty queen who admitted running a multimillion-dollar investment fraud scheme also used a portion of the stolen money for casino gambling, federal authorities say. Maria Dickerson, 47, who also used the names “Dulce Pino” and “Maria Dulce Pino Dickerson,” pleaded guilty to wire fraud and securities fraud. Prosecutors say she convinced investors to pour money into what she described as a lucrative legal-financing business. Instead, authorities say a significant portion of the cash went toward her own spending, including gambling.
