KANSAS CITY, Mo. -- The cause of that massive fire on Southwest Boulevard last week may never be determined.
Fox 4 checked with fire investigators Tuesday, and they say the cause is officially undetermined, and it seems it will stay that way.
Investigators never went inside the burned out building, and the demolition process is already underway.
Fire officials previously said there was nothing suspicious.
Firefighters chose to fight the fire at Friday's Only Furniture from the outside because there were concerns the building was unsafe to enter.
The fire quickly became a three-alarm fire.
