Since 2014, Chicago fires have killed at least 61 people in buildings where city officials knew ahead of time about fire safety problems, according to an investigation by the Better Government Association and the Chicago Tribune.

Some homes lacked smoke detectors or heat in wintertime. Some were overcrowded or didn’t have enough exits. People died in abandoned buildings the city failed to secure or demolish.

Here are details on each of these 42 fires, including news photos and excerpts from public documents, from inspection records to fire reports. To read more about how we identified these fires, read How We Reported This Story
