East Setauket, NY – Suffolk County Police Homicide Squad and Arson Section detectives are investigating a fire that killed an East Setauket woman and injured a man and infant early this morning.

Sixth Precinct officers responded to the home, located at 360 Old Town Road, after a 911 caller reported a fire at the location at 12:01 a.m. Stephen Ortner, a resident of the home, was able to escape through a second-floor window onto a roof ledge and hand his 10-month-old son to a passerby below, who then handed the child to rescuers. Ortner was then able to climb down to the ground.  

Lisa Ostrowski, 31, the mother of the child, was not able to escape the home and was found dead once the fire was extinguished. Stephen Ortner, 30, and his son Leo Ortner were transported to Stony Brook University Hospital, where the father was treated for serious injuries and his child for non-life-threatening injuries.

There were no other occupants of the home and no other injuries were reported.

A preliminary investigation has determined the cause of the fire to be non-criminal in nature.
