Okinawa Prefectural Police arrested Lance Corporal Devin Jacob Ballard, 20, of the U.S. Marine Corps Air Station Futenma on Sunday, suspecting him of killing 39-year-old local resident Anna Yagi and stealing her wallet and backpack at the Naminoue Crystal Hotel in Naha. Police say the alleged homicide occurred between 2:10 a.m. and 4:17 a.m. on Saturday, after security-camera footage captured Ballard entering the hotel with Yagi and later leaving the premises alone.

Police expect to refer the case to the Naha Public Prosecutors Office within 48 hours of his arrest.

Following his arrest, Ballard was questioned by police in Naha’s entertainment district and detained without public disclosure of his holding location. The investigation will proceed under Japanese law, with the case slated for prosecution review within the next two days. Both Japanese and U.S. officials have pledged continued cooperation as the inquiry moves forward.
