Quick Summary

A US marine, Cpl Kalvin Montoya Cardona, was arrested in Okinawa on suspicion of driving under the influence and involvement in a hit-and-run incident just before 12:30 AM local time on Saturday, despite a curfew for marines from midnight to 5 AM. This arrest follows another incident involving Lance Corporal Devin Jacob Ballard, who is accused of murdering a Japanese woman and stealing her belongings earlier this month, leading to increased scrutiny over the US military presence in Okinawa. The recurring issues have exacerbated tensions between local residents and the US military regarding crime rates among servicemen and the environmental impact of military bases.
