Just before 11 p.m., Saturday, the Zell Volunteer Fire Department with assistance from Ste Genevieve Fire Department, Bloomsdale Volunteer Fire Department, Weingarten Volunteer Fire Department, Ste Genevieve County Ambulance District and the Ste. Genevieve County Sheriffs Department responded to a first alarm residential fire in the area of Highway 61 and State Route A. The Zell FD arrived on the scene within five minutes of the initial dispatch to find a single story residence with heavy fire throughout the building. At the time of arrival it was unknown if all occupants had exited the building. Crews attempted to make an interior attack and search but were unable to due to the amount of fire throughout the building. Once the fire was extinguished an adult male was located deceased inside of the residence.
