Chicago Police Bomb and Arson and Fire Department continue their investigation of a house fire that killed two people in the northwest side Belmont Cragin neighborhood.
The fire was reported Friday evening in the 2400 block of Marmora Avenue. Firefighters who gained access to the single-family home found a man and a woman dead on the second floor.
Fire Department District Chief Timothy Sampey said the fire appeared to have started on the second floor of the 2-1/2 story frame building, where the bodies were found. The fire also spread to an attic.
A police source said a barbecue grill was found inside the vacant building, and officials are investigating whether it played a role in the fire.
Two firefighters twisted their knees while climbing a ladder and staircase, said fire district Chief Timothy Sampey. They were taken to Our Lady of the Resurrection Medical Center but their injuries were not life-threatening.
Crews had the fire out within an hour.
