NEW YORK (AP) An ex-convict who obtained millions of dollars by subjecting his daughters ex-college roommates to forced labor and prostitution was sentenced Friday to 60 years in prison by a judge who labeled him an evil genius who used sadism and psychological torture to control every aspect of his victims lives.

Lawrence Larry Ray, 63, was sentenced in Manhattan federal court by Judge Lewis J. Liman.

There is no reason to believe Mr. Ray will age out of criminal behavior, Liman said, noting that the crimes began when Ray moved in late 2010 into his daughters on-campus housing at Sarah Lawrence College, a small New York liberal arts school.

The judge said Ray charmed his victims with his exaggerated sense of self and his intelligence before robbing them of their relationships, self worth, memories and then their bodies after convincing them they had poisoned him and owed him for it.

Through psychological terror and manipulation, he convinced them what they knew to be true was in fact false, Liman said. He beat his victims. He tortured them and at times he starved them. He degraded them sexually to the point where they lost any self worth.
