Four families escaped from their burning apartment building late Thursday after waking to the sound of blaring smoke alarms.
The fire broke out about 11:30 p.m. in the apartment building near North Ridgeview Road and 123rd Terrace in Olathe.
One woman suffered smoke inhalation and was taken to a hospital with non-life-threatening injuries.
The fire caused extensive damage to the apartment building, which had four units. The cause is still under investigation.
The American Red Cross was helping about a dozen people who were displaced from the apartments.
Two dogs died in the fire.
