St. Clair County deputies were also on scene. Investigator Scott Toth said the seven structures set on fire had been torn down previously. Authorities said they did not know who started the fire, but Toth said there would be no criminal charges. He said an environmental officer is set to look into what appeared to be an illegal burn.
Firefighters at the scene requested an ambulance crew to provide medical help to four firefighters, who apparently were having difficulty due to heat. Temperatures in the 90s were causing a dangerous situation for firefighters.
Roediger said there were no injuries.
Fire crews were called from Columbia, Prairie Du Pont, Millstadt, Camp Jackson and Waterloo. Pumpers and tankers were among the trucks deployed. Roediger said Columbia Fire Department was back in service by 2 p.m.
