MOORES MILL, Ala. (WHNT) — One person was killed in a house fire in Moores Mill on Thursday evening.

Officials told News 19 crews on the scene the call came in at 4:22 p.m. Shortly after, firefighters say they found the victim and attempted to resuscitate him without success. Investigators are looking into the victim’s cause of death and how the fire started.

On-scene authorities said it took over an hour to put out the fire. The blaze was primarily contained to the attic, but filled the entire home with smoke. According to HEMSI spokesperson Don Webster, the blaze was a “fully-involved house fire.”

Webster told News 19 Moores Mill Volunteer Fire Department (VFD) responded to the fire along with Huntsville Fire and Rescue and others for mutual aid. Moores Mill VFD President Zachary Trulson said crews were still treating hot spots.

This is a developing story.
