COVINGTON - A Louisiana coroner says somebody killed a fire chief's wife before her house burned down. The sheriff says his investigation doesn't necessarily confirm that Nanette Krentel's death was homicide.

  

St. Tammany Parish Coroner Charles Preston said in a news release Wednesday that two autopsies and a forensic reconstruction all indicate homicide.

  

Sheriff Randy Smith says he and representatives of the State Fire Marshal's Office will hold a news conference about the case Thursday.

  

Krentel's husband is St. Tammany District 12 Fire Chief Stephen Krentel.

  

Her body was found in her Lacombe-area home after firefighters put out a blaze July 14.

  

DNA evidence confirmed her identity. The coroner's office reported in July that she'd died from a bullet wound..
