Three members of a family — a husband, wife and their adult son — died in a house fire early Saturday in DeRidder, according to the Louisiana State Fire Marshal’s Office.

Firefighters responded to the home in the 400 block of Memosa Street about 1:41 a.m. Nov. 7, officials said.

The victims were a 76-year-old man, his 74-year-old wife and their 39-year-old son. Their names have not been released.

Investigators with the State Fire Marshal’s Office were called to assist the DeRidder Fire Department in determining the cause of the blaze.

Preliminary findings indicate the fire started in the home’s west living room, but the exact cause remains under investigation.

“This is a tragic situation,” State Fire Marshal Chief Chad P. Sonnier said in a statement. “Our hearts and prayers are with the loved ones of those who lost their lives.”

The investigation is ongoing.
