Lawrence Ray, who sexually, psychologically and emotionally manipulated his daughter’s classmates at Sarah Lawrence College, was sentenced Friday to six decades in prison by a federal judge in Manhattan, who called Ray’s conduct “sadism, pure and simple.” “Having gained control of their minds and bodies, he forced them to do his bidding,” Liman said. Ray held so-called therapy sessions with Sarah Lawrence College students after he moved into his daughter’s on-campus housing in 2010.
