A US marine has been arrested on suspicion of murder and robbery after a woman was found dead inside a hotel room on the Japanese island of Okinawa.
The 20-year-old, named by Japanese news outlet Asahi as Devin Jacob Ballard, is reportedly stationed at Marine Corps Air Station Futenma.
He was taken into custody after the body of 39-year-old Anna Yagi was discovered in Naha early Saturday.
Police suspect the young marine killed Yagi sometime between 2 and 4am before stealing her wallet and other belongings.
The disturbing discovery was made after Yagi failed to leave the room by the hotel’s designated checkout time.
A concerned hotel employee unlocked the door and entered the room, where Yagi was found unconscious.
Emergency services were alerted at around 4.20am, but Yagi was pronounced dead at the scene.
