The coroner’s office lists 84-year-old Ross Woodward’s cause of death as a heart issue.
It says 81-year-old Rhoda Woodward died from a combination of a head injury and hypothermia.
The manner of death for both is listed as undetermined, as it’s unclear what caused her head injury.
Last month, a postal worker called 911 when he saw the bodies in the yard.
Initially their deaths were believed to be violent in nature. But after a SWAT team cleared the house and the property around it, officials determined there were no obvious injuries on the bodies that would have caused their deaths.
