A search is underway for a missing person near the New York coast after a boat carrying six people capsized on Sunday, ultimately leaving three dead and two others hospitalized.

The U.S. Coast Guard and the New York City police and fire departments are involved in recovery efforts for the remaining boater.

Coast Guard officials said they received a notification at 12:04 p.m. from New York City 911 operators about a boat taking on water near Breezy Point.

Three rescue boats and an MH65 Helicopter were deployed to assist rescue efforts already in progress by Sandy Hook Pilots and the New York Police Department’s Aviation Unit.

The identities of the boaters have not yet been released as of early Monday morning.

A sixth person is believed to still be in the water following the boat capsizing, according to the FDNY.

Authorities are investigating the incident and what caused the vessel to go under.

This is a developing story.
