Arson investigators are trying to figure out what caused the fire that burned though a southwest side home.
That fire started around 10 p.m. Saturday in the 7200 block of Somerset Rd.
Witnesses saw flames going through the roof in the back of the structure.
It took firefighters more than an hour to control the fire.
The building was a former dry cleaning business the owners had turned into their home.
The family was not home at the time of the fire.
Fire investigators say the building is totaled, and they estimate damage is at least $80,000 and could go as high as $100,000.
The Red Cross was called out to assist the family.
