A 75-year-old woman and two police officers were injured in a fire overnight Wednesday on the West Side in the Lawndale neighborhood, officials said.

Around 1:15 a.m., officers responded to a residential fire at a frame building in the 1200 block of South Kedvale where a 75-year-old woman was lying in the grass of the front lawn. The officers were injured when a porch collapsed, officials said.

Neighbors at the scene alerted police an adult son of the elderly woman was missing, but the unstable structure prevented firefighters from searching the home for other victims.

The elderly woman was taken in critical condition to Mount Sinai Hospital. The injured officers suffered non-life threatening injures.

At one point, an officer was trapped under a porch when he attempted to enter the home when alerted about the special-needs son of the woman who lived with his mother at the residence, officials said.

Firefighters plan on searching the structure once the building is stabilized, officials said. The cause of the fire was under investigation.
