Authorities in New York are expanding their investigation into a deadly explosion and fire at a residential building in the Norwood section of the Bronx after a third victim was discovered inside the property, bringing the reported death toll to three.
Firefighters and other emergency personnel responded to the building following reports of an explosion and subsequent fire. The incident caused extensive damage and prompted a major emergency response as crews worked to extinguish the flames, search the structure and determine whether additional residents were trapped inside.
The New York City Fire Department said preliminary information indicates that some type of explosion occurred before the fire, although investigators have not yet determined what caused it.
The discovery of a third body during searches of the damaged building has intensified the investigation. Authorities are working to identify the victims and reconstruct the sequence of events immediately before the explosion and fire.
Investigators are expected to examine several possible factors, including the building’s gas and electrical systems, structural conditions and any equipment or materials that could have contributed to an explosion. Officials have not yet announced a definitive cause, and authorities have cautioned against drawing conclusions while the investigation remains underway.
The incident has also raised concerns among residents in the surrounding Norwood neighborhood, where emergency crews and investigators remained focused on the affected property. Depending on the extent of the structural damage, authorities may also need to determine whether neighboring buildings face any safety risks.
Fire investigators typically examine debris patterns, utility infrastructure and witness accounts when attempting to identify the origin of an explosion and the point where a subsequent fire began. That process could take time given the damage inside the building.
The tragedy comes amid continued scrutiny of fire and building safety across New York City, particularly in older residential properties where aging infrastructure can complicate emergency incidents.
Authorities have not indicated whether criminal activity is suspected. The investigation remains active, with officials expected to release additional information as investigators determine what triggered the explosion and fire that left three people dead in the Bronx.
