Japanese police have arrested a 20-year-old US Marine on suspicion of killing and robbing a woman at a hotel in Naha, Okinawa, prompting protests from Japan’s government and local residents.

Police identified the suspect as Lance Corporal Devin Jacob Ballard and the victim as 39-year-old Anna Yagi. Ballard, who is assigned to the III Marine Expeditionary Force and stationed at Marine Corps Air Station Futenma, has reportedly denied the allegations.

Yagi was found dead in a hotel room early on October 3. Japanese media, citing investigators, reported that security footage showed a man entering the hotel with Yagi and later leaving alone with her belongings. Kyodo News reported that she appeared to have been strangled. Police allege that Ballard stole her wallet.

Prime Minister Sanae Takaichi said Japan had lodged a strong protest with the United States and urged full cooperation with the investigation, stricter discipline among US personnel and measures to prevent similar incidents. US Ambassador George Glass offered condolences and pledged full cooperation. Okinawa Governor Genta Koja called the case “absolutely unforgivable.”

About 100 people protested in Naha on Sunday, while people also protested in Tokyo, according to the BBC. The arrest has renewed local anger over crimes involving US personnel. About 54,000 US military personnel are stationed in Japan, with most based in Okinawa.

WHAT THE EDITOR DID

The second model checked the writer's draft against the same sources and changed it before publication. Struck words were in the draft; underlined words are its corrections.

WHAT IT FLAGGED editor revise: Two attribution/details issues can be fixed by tightening the wording to match the sources. - "Prime Minister Sanae Takaichi said Japan had lodged a strong protest with the United States and demanded full cooperation with the investigation, stricter discipline among US personnel and measures to prevent similar incidents.": The sources say Takaichi urged or demanded maximum/full cooperation, strict discipline and measures to prevent recurrence, but do not support that she personally said all of these details in one statement as phrased. - "About 100 people protested in Naha on Sunday, while another demonstration was held in Tokyo, according to the BBC.": The BBC says some 100 people protested in both Naha and Tokyo, while other sources specify around 100 outside the Okinawa prefectural government building; this wording implies the BBC reported only about 100 in Naha and an unspecified separate Tokyo demonstration.
