Krause says crews arrived within two minutes of getting a 911 call and found flames coming from an upstairs window.

Krause says they pulled a 1-year-old girl from the town house and she was later pronounced dead. He says the 3-year-old boy was taken to a hospital, where he was in critical condition. Names weren’t immediately released. Krause says the children had smoke inhalation, not burns.
