It appears all ten of the people who died in the group home fire in Anderson early yesterday morning died of smoke inhalation. Autopsies are being done on the victims today in Springfield. One staff member and nine clients were killed the fire. One of the residents of the home was not there at the time of the fire. The home did not have a sprinkler system but it did have a fire alarm system. Investigators from four state and federal agencies are still looking at the wreckage to determine a cause of the fire.
