Children, 8 and 10, a mother and a grandfather in Frayser are dead following a house fire early Tuesday.
A surviving father, who arrived to find his house in flames, tried to bust windows in an attempt to save his family. But he and neighbors were not successful, according to ABC24.
He was taken to Regional One Hospital's burn unit in critical condition.
It took firefighters about 20 minutes to bring the flames under control. No firefighters were injured.
Firefighters have not determined if smoke alarms were present.
