A small plane crashed into Setauket Harbor, Long Island Sound, New York, on February 20.
The Piper PA-28 was flying from Massachusetts when it lost engine power, prompting the pilots to make a crash-landing.
There were four people aboard at the time, including the student pilot Austricio Ramirez who was flying the plane when it began experiencing issues, and the instructor pilot Nelson Gomez who took over the control afterwards and landed the plane in Setauket Harbor.
Authorities said Ramirez, Gomez, and a third passenger Wady Perez were rescued by the officers. The fourth person, identified as 23-year-old Gerson Salmon-Negron, remains missing.
The FAA and the NTSB are investigating.
