A Eudora house fire that drew fire crews from three area departments Tuesday night appears to have started in the home’s chimney, officials said Wednesday.

Fire crews responded to the house fire in the 2200 block of Quail Court, on the south side of Kansas Highway 10 and just east of Eudora High School, about 11:40 p.m. Tuesday, as reported by the Journal-World’s news partner, Operation 100. The second story of the house was engulfed in flames and the roof collapsed about an hour later.

The fire was declared under control around 1:10 a.m.

The home was owned by Steve Spence and Mary Kay Gregory. Everyone in the house escaped safely, and no injuries were reported.

Eudora City Fire Chief Ken Keiter said state fire investigators believed the fire spread from the home’s working fireplace — which the residents were using at the time — into the upper reaches of the chimney and caused a fire in the attic. The residents said they were not aware the house was on fire until a passing motorist knocked on their door to alert them. They had dismissed the activation of their smoke alarms, thinking it was caused by the fireplace.

The house would most likely be declared a total loss, Keiter said, and the residents are staying with local family members.

Keiter advised people to make sure their smoke alarms are working properly and to investigate their home for danger if the alarms sound.
