Investigators are working to determine how a man died after he was found in a Binghamton fire department following a blaze.

Authorities say firefighters were sent to 13 John Street on the city's South Side around 4:30 p.m. Thursday.

Police say a small fire was extinguished on the second floor of the building. Firefighters discovered an "unresponsive" man in an apartment.

Detectives say the man sustained injuries before the fire broke out. It's unclear how the blaze started.

Firefighters who found the man called for an ambulance, reporting he had sustained gunshot wounds. But police chief Joseph Zikuski told WNBF News at the scene that no gun was found and the man apparently had not been shot.

The man's body was taken to Wilson Medical Center in Johnson City where an autopsy will be performed.

No injuries were reported to firefighters or other occupants of the three-unit apartment building.

One resident said he heard nothing out of the ordinary before firefighters arrived.

The owner of the building declined to comment to a reporter at the scene.

The Red Cross was called to assist residents who were displaced following the fire.
