Broome County Fire investigators today will be looking into the cause of a blaze overnight that left a Windsor hunting club in ashes. 

The building on Grange Hall Road actually falls into the Hallstead Fire district. 

Responders found the structure totally engulfed in flames when they arrived at the scene at around 12:02 a.m.

Soon after firefighters got to the site, the building collapsed. 

There was no one in the structure when the fire broke out.  Crews from Great Bend, Hallstead, Windsor, Kirkwood and Five Mile Point were dispatched.

Broome County Emergency Services officials say New York State Electric and Gas personnel were the last to leave the scene at 3:35 a.m.
