Narrative:

At departure time (HT30 pm local dtw time), the lead flight attendant noticed an unusual odor in the cabin and thought there might be smoke but wasn't sure. I went back and there was definitely an unusual smell, but I did not think there was smoke. We turned the air conditioning packs off and called maintenance and informed the gate agent of a delay. With the packs off, the smell didn't seem to get better. But seemed to be getting worse. I made an announcement for the people to deplane. Toward the end of the deplaning, the smell was getting worse and smoke was definitely visible in the cabin. A mechanic showed up at this time, and after a short time trying to ascertain the problem, with his concurrence I shut power off to the aircraft and the fire fighters were called. After this, the smoke became progressively thicker and seemed to be coming from behind the front flight attendant jump seat. The fire fighters soon arrived and took over. Supplemental information from acn 221243. The location of the fire was eventually located on the circuit breaker panel behind the flight attendant jump seat on the bulkhead between the cabin and cockpit.
