A U.S. Coast Guardsman died Sunday from injuries received during a security patrol near Vashon Island.

Two 25-foot, fast-response boat crews from a Coast Guard Maritime Safety and Security Team were involved in a security patrol and training mission north of Vashon Island at approximately 2:15 p.m. when a Coast Guardsman was ejected from a vessel. A third 25-foot response boat was operating in the area and came to the Coast Guardsman's aid.

The Coast Guardsman was transported to the Fauntleroy Ferry Terminal for transport by ambulance to Harborview Medical Center, where he was pronounced dead.

The identity of the crewmen is being withheld pending notification of next of kin. The accident is under investigation.

Coast Guard security operations have not been interrupted.
