SHREVEPORT, La. (AP) — One man is dead and a 17-year-old critically injured in an early morning apartment fire in Shreveport.

Firefighters responded to the fire just before 2:30 a.m. Friday.

Authorities say 30-year-old man was found dead inside the apartment. Firefighters say a 7-year-old was revived at the scene and sent to the hospital.

Firefighters say it appears the man went back into the apartment to rescue the 7-year-old but collapsed from the smoke.

The cause of the fire is under investigation.
