The sheriff of St. Tammany Parish is confirming his department is being assisted by the FBI in an ongoing investigation into the death of a fire chief's wife.
Nanette Krentel was found shot to death and severely burned at the couple's home in July. A news release issued yesterday says firearms were found near the woman's body and that one of them may have been used to kill her.
The sheriff announced several weeks ago that her husband had been ruled out as a suspect.
