Investigators are back on the scene of an apartment complex fire that broke out on Saturday.
The massive fire destroyed the building on Edgewood Drive in Nicholasville.
Officials say the fire at the vacant building is suspicious. They also say no one has lived inside the apartment complex for quite some time now.
Fire investigators say the heavily damaged building is slowing down their efforts because the damaged building poses a dangerous threat.
Officials say they believe the fire was started from inside the building. Investigators have been seen taking evidence in and out of the building throughout the afternoon.
Fire investigators say the cause of the fire could take days, even weeks before it's determined.
