Nassau police Homicide and Arson Bomb squads are investigating a Massapequa house fire that left an occupant dead and three firefighters injured.

Police and the Massapequa Fire Department responded at 11:39 a.m. Monday to the home on Bayview Street East near Shinnecock Avenue and encountered a residence "fully engulfed in flames," police said. The occupant was found inside a small room located at the front of the home, police said. A Nassau police medic pronounced the victim dead at the scene, according to authorities.

One firefighter injured a foot and was taken to a hospital for treatment, police said. Another firefighter temporarily "lost consciousness" while a third suffered a burn to the neck, police said, adding that both were treated at the scene.

Nassau County Chief Fire Marshal Michael Uttaro said the fire's cause has yet to be determined but is not considered suspicious.
