A Shreveport man has been sentenced in an investment scheme. The Caddo Sheriff's Office says 49-year-old Stanley Mangham pled guilty in April to theft of the assets of an aged or disabled person after a Sheriff's Office investigation. An investigator and three victims testified before Caddo District Judge Scott Crichton in a sentencing hearing. Mangham has been sentenced to eight years in prison at hard labor. He also has to pay a $3,000 fine and pay the victims over $200,000 in restitution when he's released. He's still under investigation for other offenses.
