Okinawa prefectural police transferred a detained US Marine to prosecutors on Oct 5 over the killing of a woman at a hotel in Naha, Okinawa, China News Service and Jiemian reported. China News Service named the suspect as Devin Ballard, while Jiemian gave the name as Devin Jacob Ballard, a 20-year-old private first class in the US Marine Corps assigned to Marine Corps Air Station Futenma in Okinawa.

Police arrested the Marine on Oct 4. According to the allegations reported by both outlets, he killed a Japanese woman at a hotel in Naha early on Oct 3 and took her wallet and other belongings. China News Service reported that the Marine is suspected of robbery and murder. [ 1 , 2 ]
Jiemian, citing Japanese media, reported that the victim was a 39-year-old Japanese woman and that cord-like material was wrapped around her neck, with marks indicating strangulation; the cause of death appeared to be suffocation from pressure on the neck. The same report said surveillance footage from near the scene showed a man believed to be foreign entering the room with the woman and later leaving the hotel carrying belongings, and that his hairstyle and tattoos closely resembled Ballard’s characteristics. [ 2 ]
Jiemian also reported that Ballard denied the allegation during the investigation, saying “I don’t know about this”. [ 2 ]
Prime Minister Sanae Takaichi, speaking on Oct 5 before her policy speech at an extraordinary Diet session, said she found the incident “extremely regrettable” and expressed a “strong protest” to the United States, China News Service reported.

China News Service noted that crimes involving US personnel in Japan have been frequent over the years, including rape, murder and robbery, and cited statistics showing that Okinawa police handled more than 100 criminal cases involving US military personnel and related people in 2025 alone. [ 1 ]
Why it matters
The case again focuses attention on crime by US service members in Okinawa, where the documents say such incidents have long been frequent and where the prime minister publicly demanded measures to stop a recurrence.
