Investigators found a burnt mattress and some old furniture among the remains at 107 Philema Road.
Firefighters were called to the empty building sometime after three Saturday morning.
They spent several hours fighting flames that caused the whole structure to implode on itself.
Investigators say it will take several days to sift through all the debris to determine the cause or find out if anyone died in this fire.
This building was the old Cab Stand Nightclub, but has been vacant for several years.Feedback
