While an autopsy of an 89-year-old woman found dead outside the local Goodwill store indicates the cause of the death was natural, it is not known if those natural causes were helped along by alleged neglect by the woman’s daughter. A preliminary examination was held Tuesday in the death of Mary Gertrude Grenia, concluded with the call for briefs to be submitted to St. Clair County District Court Judge John Monaghan before he makes a decision on whether or not to bind the case over to Circuit Court. 49-year-old Kelly Rhodes of Oregon was arrested on March 20 in Belleville, Ill., after the body of her mother was found outside Goodwill Industries in Port Huron Township. The misdemeanor charge of moving a dead body without a medical examiner’s permission was changed last week to include additional charges of open murder and vulnerable adult abuse in the second degree. In the autopsy report, St. Clair County Medical Examiner Daniel Spitz decided the cause of death as among other issues as heart and lung disease. He added that it’s possible neglect in the form of dehydration, malnutrition or hypothermia could have affected the natural disease. A decision by Monaghan is expected by July 9.
