QUINCY -- The cause of a Saturday morning fire, which damaged a Quincy apartment, remains under investigation.
Quincy firefighters were called to 511 N. 15th at 8:37 a.m. and found smoke and fire showing through a second-story window of the four-unit apartment building.
"The guys were able to hit it with a hose line from outside, make access through a rear staircase on the exterior of the building, then went in and put it out," Assistant Chief Scott Lucey said.
Lucey said the fire was contained to the apartment unit and did not spread into the attic.
Thirteen firefighters battled the blaze, and two investigators also were on the scene.
"We could see flames through the air conditioner unit, but it wasn't the air conditioner that caused it. It wasn't even plugged in," Lucey said.
No injuries were reported.
Lucey said the Quincy Police Department was instrumental in helping get the occupants out of the building, and the Red Cross was called to help care for the residents. The apartment where the fire started was uninhabitable; the other three units had "just a little bit of moderate smoke smell, but it was best to air out overnight," Lucey said.
The apartment did not have working smoke detectors or carbon monoxide detectors, but Lucy said they had been provided to the building.
