Miami police have identified the woman who died shortly after firefighter pulled her from a smoke-filled home Wednesday.

The woman is Cheryl Farnell, 58, who lived in the rear unit of a duplex in the 6300 block of Northwest 17th Avenue, according to Miami police.

Hours before the fire, the family that lives in a front unit heard a commotion, Miami Fire-Rescue spokesman Lt. Ignatius Carroll said. One person looked around outside but saw nothing suspicious. Then, about 9 a.m., a man and woman inside the home felt their eyes burning, and called 911.

When firefighters arrived, the family told firefighters they thought smoke was coming from the rear unit.

Firefighters found heavy smoke and Farnell unresponsive on the bedroom floor. Investigators believe she had trouble walking because they found a walker in her room.

Paramedics took her to Jackson Memorial Hospital’s Ryder Trauma Center, where she died.

What caused the Liberty City fire and her death remains under investigation, but Miami firefighters believe cigarette butts found near her recliner might have sparked the fire.
