Story summary
On Saturday, a 39-year-old woman named Anna Yagi was found dead inside a hotel room in Naha, Okinawa, Japan. Police suspect that she was murdered between 2 and 4 AM by a 20-year-old US Marine, identified as Devin Jacob Ballard, who is stationed at the Marine Corps Air Station Futenma in Okinawa. Security footage showed Ballard entering the hotel with Yagi but leaving alone later on. When the hotel staff entered the room after Yagi failed to check out by the designated time, they found her unconscious; she was pronounced dead shortly afterward.
Ballard was arrested on Sunday morning, and he has denied the allegations. The incident led Japan’s foreign minister and vice-minister to protest to the US ambassador in Tokyo, urging full cooperation with the investigation and measures to prevent similar incidents. Both governments have confirmed they are working together to resolve the case.
