CHICAGO (AP) — Two men killed in a fire at a high-rise building on Chicago's South Side helped rescue an elderly woman and tried to stop the blaze.

The Cook County medical examiner identified the victims as 50-year-old John Fasula and Jameel Johnson, who was in his 30s. The Tuesday fire injured one other person and drove residents into frigid temperatures.

Authorities and relatives say both men were working in the building. They went to assist a resident in her 70s after hearing her screaming. Authorities say they got her to an elevator and sent her down to the lobby. She collapsed and was transported to a hospital.
