(PORT HURON) -- The sentencing for an Oregon woman who pleaded guilty to dumping her mother's body at a Port Huron Township thrift store has been rescheduled. 49-year old Kelly Rhodes had been charged with murder, but last month pleaded guilty to a lesser charge of manslaughter, fourth-degree vulnerable adult abuse, and removing a dead body without permission of a medical examiner. Authorities believe neglect had a role in the death of 89-year-old Mary Grenia of Salem, Oregon, last March. Grenia died inside a truck at a truck stop after she and Rhodes were turned away from entering Canada on the Blue Water Bridge. An autopsy revealed heart and lung disease but no sign of trauma. Rhodes is scheduled to be sentenced on January 2 at 10 a.m. in St. Clair County court.
