CHAMPAIGN, Ill. (WAND) - Investigators said they are not able to determine the exact cause of a fire at a Champaign church.

Champaign and Urbana Fire Departments responded to a church fire early Monday morning. 

Crews responded  to Mt. Olive Missionary Baptist Church on East Bradley Ave. in Champaign just after 3 a.m.

The call was quickly upgraded to a second-alarm fire. 

Crews used aerial devices to extinguish the large fire. Chief Gary Ludwig says, crews were able to contain the fire to one section of the church. 

Chief Ludwig went on to explain the cold weather caused some hazards for crews Monday morning. Salt trucks were used to help clear ice off the parking lot. 

One local church member, Phyllis Clark said right now they are still trying to process the loss of their second sanctuary.

"I mean, you know, we've put a lot into this church and we give a lot to this church. To have it to go up like that it's just heart wrenching and hopefully we can bring it up to the place where it should be," said Clark.

Monitory donations will be accepted in their main church lobby and are asking for physical help to reconstruct the sanctuary. At this time, they still don't know when they will be reconstructing or if they will reconstruct. They are just happy that no one was hurt in the fire.

The attic above the sanctuary sustained heavy fire damage. The roof collapsed within minutes of firefighters arriving on scene.

The fire started in the attic. Most of the mechanical features, such as heating, ventilation, and air conditioning, were in the attic.
