MANHATTAN – A mysterious death under investigation on the Upper East Side had police officers going in and out of a building on East 81st Street for more than three hours on Thursday after authorities say a 24-year-old man was found unconscious and unresponsive at the same location.
A neighbor who saw the commotion and spoke with Upper East Site says around 5:00pm Thursday, the unresponsive man was spotted sitting inside a Toyota parked nearby when a woman walking past spotted that he needed help and called 911.

That woman, who a neighbor says identified herself as nurse, alerted residents of the building on the first floor through an open window.

The residents then took the unresponsive man to the hospital, the neighbor says, before an ambulance arrived. Investigators tell Upper East Site the 24-year-old man was pronounced dead at Lenox Hill Hospital.

Outside the building on East 81st Street between First and York Avenues, a police cruiser sat late into the night— inside the building around 10pm, three officers could be seen going in and out of first floor apartment.

The front window was wide open, as well as the front door, which was missing its locks and door handle— apparently taken off by investigators to get inside the apartment for a search. Police say the incident was reported to them at 7:34 pm, and witnesses say they saw NYPD detectives on the scene as well.

Officers were also seen keeping a man from entering the apartment, a neighbor tells Upper East Site he was one of the residents in the window earlier in the day.
The NYPD is not releasing the name of the man who passed away until his family can be notified. Investigators say the medical examiner will determine his cause of death.
