Superheated air is being blamed for the deaths of a husband and wife in a fire in west suburban Naperville.

The DuPage County Medical Examiner says Thomas and Janet Lambert died from breathing in extremely hot air after their house caught fire last December.

Two others were hurt in the fire.

The Naperville Fire Department says the cause remains under investigation.
