The body of a 42-year-old man was found on the eastbound platform of the Long Island Rail Road station in Riverhead Tuesday night, officials said.
The body was reported about 10:35 p.m. by a passer-by, a spokesman for the railroad said.
The official cause of death has not been determined, but it appeared to be due to natural causes, the spokesman said.
It was not known if the passer-by who reported the body was a passenger.
CORRECTION: An earlier version of this story misstated the time the body was found because of incorrect information from the railroad.
