BRIDGEPORT - Fire officials in Bridgeport are investigating a fatal fire involving a 7-year-old.

It happened around 5:30 a.m. at a home on Highland Avenue.

Fire officials say there were nine people inside when the blaze broke out.

They say the body of Kyle Jean-Baptiste was found underneath a mattress.

His mother apparently told firefighters her son was trapped upstairs but the blaze was too intense to make an immediate rescue attempt.

The state fire marshal as well as local investigators are on the scene trying to determine how this fire started and how the boy died.
