報道要點
Princeton搜救志願者Marion Weiskopff與經過氣味訓練的騾Sonny，參與尋找2023年在亞利桑那失蹤的Chelsea Grimm。私人調查人員希望在約400平方公里偏遠地區找到線索，先前使用越野車、無人機及搜救犬均未有決定性結果。
背景與影響
Sonny在美國受訓並參加過嗅聞比賽，騎乘搜索有助進入人行難達地形。此次它帶領人員找到一塊女鞋鞋底，但尚不能確認屬於失蹤者；暴雨泥濘隨後令騎乘行動因安全暫停，團隊希望天氣轉幹後繼續。
仍待確認
Princeton騎乘搜救組有五名受訓志願者，除一般資格外須完成額外60項任務。嗅聞並非該組現行正式認證技能，Sonny此次也是首次因這項能力受邀；報道不證明其已找到失蹤者或解決案件。
