原因不明のまま捜査終結　首里城火災で沖縄県警

　那覇市の首里城で正殿などが焼失した火災で、沖縄県警は２９日、放火や失火など刑事責任を問う事実は見当たらないとする捜査結果をまとめた。「出火原因は特定できなかった」とし、捜査は原因不明のまま終結した。
　県警は、激しく燃えていた正殿北東部を中心に調べ、火災で燃えた電気配線とみられる金属片を鑑定した。しかし、ショートの痕は見つからず、電気系統のトラブルと断定できなかったという。（2020/01/29-19:18）

Police have ended their investigation into last autumn's fire that devastated Shuri Castle in Naha, the capital of the southernmost Japan prefecture of Okinawa, without identifying the cause.
   The fire was not caused by arson, negligence or other reasons for which a criminal liability can be established, according to a report of the investigation results disclosed by the Okinawa prefectural police Wednesday.
   The police closely investigated the northeastern section of the "Seiden" main hall, which burned furiously, and scrutinized metal fragments that are believed to be burned electric wiring.
   With no signs of a short circuit found, the police could not conclude that the fire occurred due to an electric system problem.
   No intruder was seen on video footage from 68 security cameras in Shurijo Castle Park. The police found no evidence of negligence related to the fire.
