Chicago Firefighter Jermaine Pelt, 49, was killed in a house fire early Tuesday.
He collapsed as he and others were ordered out of the house. A lieutenant grabbed him and removed him, WGN reported, adding that crews immediately attempted life-saving measures.
Fellow firefighters and Chicago Police escorted Pelt's body to the Cook County Medical Examiner's office.
He is survived by his wife, a six-year-old and a daughter he recently walked down the aisle.
She was notified of his death while on her honeymoon.
Two other firefighters injured are expected to recover.
