An autopsy has determined that the death was not suspicious

An autopsy has determined that the death of a man awaiting trial on charges of killing his mother off the coast of New England in a scheme to inherit millions of dollars was not suspicious, the New Hampshire attorney general’s office said Wednesday. Nathan Carman, 29, of Vernon, Vermont, was found dead in his cell in a county jail in New Hampshire on June 15. The U.S. Marshals Service in Vermont said it will not be releasing the cause of Carman’s death at the request of family. The attorney general’s office confirmed that authorities consider a death to be not suspicious when they’ve determined no one else was involved, or if no crime was committed. Carman pleaded not guilty last year to fraud and first-degree murder in the 2016 death of his mother, Linda Carman, and was scheduled to go on trial in October. An eight-count indictment also said Carman shot and killed his wealthy grandfather in 2013 as he slept, in order to obtain money and property from his grandfather’s estate. But the indictment did not charge Carman with his grandfather’s killing, and he had consistently denied any involvement in the two deaths.
