DENHAM SPRINGS — The Livingston Parish Sheriff’s Office on Thursday investigated a shooting in which an 80-year-old man is believed to have killed himself after shooting his 71-year-old wife.

The woman, who lives in the 8100 block of Cecil Drive, called 911 at 12:51 a.m. Thursday to report she had been shot by her husband, Sheriff’s Office spokeswoman Lori Steele said in a news release.

While the woman was speaking with the 911 operator, the husband turned the firearm on himself, Steele said.

The Coroner’s Office pronounced the man dead at the scene. The woman was taken to a hospital for treatment of injuries believed to be non-life-threatening, Steele said.

No motive for the shooting has been determined, Steele said.
