John Heath said he did not know what had happened to his wife.Heath remarried the following year, to a woman who baby-sat their daughter, according to his arrest affidavit. Elizabeth Heath’s sister-in-law told police that Elizabeth feared her husband was going to kill her and said that if anything ever happened to her, “you know that John did it,” according to an affidavit.The medical examiner’s office determined that Elizabeth Heath died from blows to the head.Her remains, wrapped in bedding and garbage bags, were found in 2010 at the couple’s former property in Newtown, where the new owner came upon them while tearing up the barn floor.
