An 18-year-old man was found dead Wednesday less than a mile from his Hicksville home three days after he was reported missing, Nassau County police said.

Kieran Walsh’s body was found near the corner of South Oyster Bay Road and Stewart Avenue, but Homicide Squad detectives do not suspect that he was a victim of foul play, police said.

His body was taken to the Nassau County Medical Examiner’s office, where an autopsy will be conducted to determine his cause of death.

Walsh had been last seen at his Prince Street home shortly after midnight Monday when he was reported missing.
