INDIANA, Pa. -- No unusual traces of a toxic metal or any other chemicals were found in a woman whose body was exhumed as part of an ongoing poisoning investigation, WTAE's Shiba Russell reported Thursday.

The Indiana County Coroner's Office said the results show there is no link between the death of 58-year-old Anna Nagg, who died in 2001, and 61-year-old Russell Repine, who died in March 2002.

Repine's cause of death was initially listed as a heart attack, but a routine autopsy blood test later showed that the Homer City man had a lethal amount of cadmium in his body.

Coroner's officials said they exhumed Nagg's body based on information from unidentified sources that her death and Repine's might be linked.

Chief Deputy Coroner Michael Baker said the investigation into Repine's death will continue. The coroner's office is working with state police on the case.

The official cause of Repine's death has been changed to cadmium poisoning. Investigators are still trying to determine if it was an accident, suicide or homicide.

Nagg's cause of death has been changed from pneumonia to organ failure from natural causes, Baker said.
