The great-granddaughter of the heiress to the General Foods cereal fortune was found stabbed to death in her luxury spa on the Central-American island of Roatan, police in Honduras said. Roatan Police Chief Alex Edgardo Madrid told NBC News Friday that Nedenia Post Dye, 46, of Santa Monica, Calif., was found dead on Dec. 22, at her residence in the resort town with multiple stab wounds to the back. Dye was the great-granddaughter of businesswoman Marjorie Merriweather Post, who inherited the Post Cereal Company empire in the 1910s at age 27. The company would later become the General Foods Corporation, one of the world's largest food companies. Madrid said police arrested a local musician, Lenin Roberto Arana, and charged him with murder. Arana, who goes by the stage name "Canario" ("The Canary") was apprehended while trying to flee in Dye’s vehicle, Madrid said. He added that Arana said the two were romantically involved.
