This case report describes novel methodology used to identify a 43-year-old post-mortem photo of a drowned male recovered from a London river in the 1970s. Embedded in an array of foils, police super-recognisers (n=25) possessing superior simultaneous face matching ability, and police controls (n=139) provided confidence ratings as to the similarity of the post-mortem photo to an ante-mortem photo of a man who went missing at about the same time. Indicative of a match, compared to controls, super-recognisers provided higher ratings to the target than the foils. Effects were enhanced when drawing on the combined wisdom of super-recogniser crowds, but not control crowds. These findings supported additional case evidence allowing the coroner to rule that the deceased male and missing male were likely one and the same person. A description of how similar super-recogniser wisdom of the crowd procedures could be applied to other visual image identification cases when no other method is feasible is provided.
本病例报告描述了一种新颖的方法，用于鉴定一张 20 世纪 70 年代从伦敦河中打捞上来的、43 岁溺水男性的死后照片。在一系列箔片中，拥有卓越同时面部匹配能力的警方超级识别员（n=25）和警方对照组（n=139）对死后照片与同一时期失踪的一名男子的生前照片的相似性提供了置信度评分。与对照组相比，指示匹配的是，超级识别员对目标的评分高于箔片。当利用超级识别员群体的集体智慧时，效果会增强，但利用对照组群体的智慧则不会。这些发现支持了额外的案件证据，使验尸官能够裁定死者和失踪者可能是同一个人。文中还描述了在没有其他可行方法的情况下，如何将类似的超级识别员群体智慧程序应用于其他视觉图像识别案件。
