A young female sailor took her own life Thursday night aboard her assigned ship, the USS Essex, in San Diego.

The unidentified 19-year-old woman was found by medical personnel with a gunshot wound aboard the ship last night, and pronounced dead soon after at the UCSD Trauma Center, according to NBC San Diego.

Navy officials confirmed Friday morning the death was a suicide, reports L.A. Now.

It is not clear if the weapon belonged to the woman, or how it came to be on the ship.

The USS Essex is an amphibious assault ship; its home port is San Diego.
