Japan protests to U.S. after Marine arrested over Okinawa killing

Japanese police have arrested a 20-year-old U.S. Marine on suspicion of killing and robbing a 39-year-old woman at a hotel in Naha, Okinawa, prompting a protest from Japan’s government and demonstrations by local residents.

Police identified the suspect as Lance Corporal Devin Jacob Ballard, stationed at Marine Corps Air Station Futenma, and the victim as Anna Yagi. She was found dead in a hotel room early Saturday. NHK reported, citing police, that she died from pressure to her neck.

Investigators said security footage showed a man believed to be the suspect entering the hotel with Yagi and later leaving alone with her belongings. Police found Ballard late Saturday in an entertainment district and arrested him Sunday on suspicion of murder and robbery. He has denied the allegations, according to Japanese media.

Prime Minister Sanae Takaichi called the incident heinous and said Japan had lodged a strong protest with the United States, seeking full cooperation with the investigation, stricter discipline among U.S. personnel and measures to prevent similar cases. Foreign Minister Toshimitsu Motegi summoned U.S. Ambassador George Glass, who offered condolences and pledged cooperation. The III Marine Expeditionary Force also said it was cooperating with Japanese authorities.

About 100 people protested in Naha, while another demonstration was held in Tokyo. Okinawa hosts a large share of the roughly 50,000 to 54,000 U.S. troops stationed in Japan, and crimes involving American service members have long fueled local opposition to the military presence.

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: The story is otherwise supported, but the lead should distinguish Japan's diplomatic protest from residents' demonstrations. - "Japanese police have arrested a 20-year-old U.S. Marine on suspicion of killing and robbing a 39-year-old woman at a hotel in Naha, Okinawa, prompting protests from Japan’s government and local residents.": The sources say the arrest prompted public outrage and protests by local residents, while Japan's government lodged a protest with the United States; describing both as 'protests from Japan’s government and local residents' is misleading. - "prompting protests from Japan’s government and local residents.": This wording suggests Japan's government held protests rather than lodging a diplomatic protest, which is materially misleading.
