美国军方官员周四透露，在新的法医技术未能取得进展后，一张旧照片帮助识别出了一名在朝鲜战争服役期间牺牲的二战退伍军人的遗体。
根据美国国防部战俘/失踪人员会计局（DPAA）的信息，25岁的美国陆军中士罗杰·迪凯纳（Roger Duquesne）于1950年9月被分配到第25步兵师第89中型坦克营A连。9月3日，他在朝鲜马山附近（现属韩国）与朝鲜军队作战时被报告失踪。DPAA称，迪凯纳当时正在寻找备件包时失踪。他于1953年12月31日被宣告死亡。

通常情况下，DPAA会使用法医技术和历史研究来识别阵亡士兵的遗体。但一组作为朝鲜战争无名烈士埋葬的遗体却无法通过这一流程确认身份。这些遗体于1950年9月在韩国洛东江附近被发现，并于1956年安葬在夏威夷檀香山太平洋国家纪念公墓（National Memorial Cemetery of the Pacific）。2011年10月，这些遗体被重新发掘。
遗体接受了多次检查。寻找家属DNA比对的尝试失败了，牙科记录也因缺乏可比较的独特特征而无法使用。DPAA表示，许多朝鲜战争案例中使用了胸部X光片，但这些遗体没有此类记录。
DPAA工作人员转而采用了一种名为颅面叠加（craniofacial superimposition）的法医方法。该方法将失踪人员的照片与待识别的头骨图像进行比对。这种方法有些过时，昆士兰大学副教授卡尔·斯蒂芬（Carl Stephan）在DPAA的新闻稿中表示，它”一直存在一些科学障碍”，包括照片失真，但视频技术的新进展使其准确性有所提高。
专攻颅面识别方法的斯蒂芬与DPAA合作，尝试用该方法识别无名遗体。DPAA调查人员将迪凯纳生前的照片与头骨进行了比对。在一张照片中，迪凯纳戴着军礼服帽，这一参照物可用于确定拍摄角度。

“你会找不到匹配、找不到匹配、还是找不到匹配，”斯蒂芬在DPAA的新闻稿中说，”然后出现一个最佳匹配点，接着又找不到匹配。这告诉你相机需要距离参照物多远。”
一旦确认了相机的距离，DPAA调查人员仔细调整头骨的位置，使其与照片中迪凯纳面部的姿态相匹配。DPAA称，他们拍摄了迪凯纳面部照片叠加在头骨上的图像，并研究其”解剖学一致性”。”最有说服力的证据来自牙齿：照片中，迪凯纳面带微笑，露出上牙，包括一颗突出的上犬齿，其阴影覆盖了其他牙齿。当头骨位置正确时，也产生了同样的阴影。”
“这是表明身份匹配的决定性因素之一，”斯蒂芬说。

DPAA调查人员还利用历史记录排除了所有其他可能的候选人，以确保遗体确实是迪凯纳的。DPAA表示，此案现在”清楚地表明，旧的法医技术可以得到改进，而不是被摒弃，经过深思熟虑应用的严谨科学仍然可以在数十年后为最困难的身份识别带来清晰和答案。”
迪凯纳的遗体于去年9月被DPAA确认身份，但该机构直到本周才详细说明这一识别过程。他的名字已被刻在太平洋国家纪念公墓的”失踪者法庭”和华盛顿特区的朝鲜战争退伍军人纪念墙（Korean War Veterans Memorial Wall）上。
根据DPAA的数据，自1982年以来，已有超过450名在朝鲜战争中牺牲的美军士兵遗体被识别并归还给家属，目前仍有约7000名美军在战争中下落不明。
After newer forensic tests fail, old photo helps identify remains of U.S. soldier who died in Korean War

The remains of an American World War II veteran who died while serving in the Korean War have been identified thanks to an old photograph after newer forensic techniques came up short, U.S. military officials revealed on Thursday.
U.S. Army Sgt. Roger Duquesne, 25, was assigned to A Company, 89th Medium Tank Battalion, 25th Infantry Division in September 1950, according to the Defense POW/MIA Accounting Agency. On September 3, he was reported missing in action while fighting North Korean forces near Masan, Korea, which is now part of South Korea. Duquesne disappeared while searching for a spare-parts kit, the DPAA said. He was declared dead on Dec. 31, 1953.

Typically, the DPAA uses forensic technology and historical research to identify the remains of fallen soldiers. But a set of remains buried as a Korean War Unknown defied that process. The remains were recovered near South Korea’s Naktong River in September 1950, and buried as unknown at the National Memorial Cemetery of the Pacific in Honolulu, Hawaii in 1956. The remains were disinterred in October 2011.
The remains underwent multiple examinations. Attempts to find a familial DNA match failed. Dental records were checked, but there were few distinguishing features to be compared. Many Korean War cases involve the use of chest radiographs, the DPAA said, but no such records existed for these remains.
DPAA workers turned their attention to a forensic method known as craniofacial superimposition. The method compares a photograph of a person believed to be missing with images of the skull being identified. The method is somewhat outdated and University of Queensland associate professor Carl Stephan said in a DPAA news release that it has “always had some scientific hurdles,” including photographic distortion, but new advances in video technology have helped make it more accurate .
Stephan, who specializes in craniofacial identification methods, worked with the DPAA to see if the method could identify the unknown remains. DPAA investigators compared an photo of Duquesne when he was alive to the skull. In one image, Duquesne was wearing a military dress hat, which could be used as a reference object to determine where to place the camera.

“You’ll find no match, no match, no match,” Stephan said in the DPAA news release, “then a sweet spot, and then no match again. That tells you how far the camera needs to be away from the reference object.”
Once the camera’s distance had been confirmed, DPAA investigators carefully positioned the skull so it matched the pose of Duquesne’s face in the image. A photo of Duquesne’s face overlaid on the skull was taken and studied for “anatomical consistency,” the DPAA said. The “most compelling evidence” came from the teeth: In the photo, Duquesne is smiling and showing his upper teeth, including a prominent upper canine that throws a shadow across other teeth. When the skull was positioned correctly, the same shadow was produced.
“That’s one of the decisive things that indicates this is a match,” Stephan said.

DPAA investigators also used historical records and excluded all other possible candidates to ensure the remains were correctly identified as Duquesne’s. The DPAA said the case is now “a clear example of how older forensic techniques can be refined rather than discarded, and how careful science, applied thoughtfully, can still bring clarity and answers to even the most difficult identifications decades after the fact.”
Duquesne’s remains were accounted for by the DPAA in September, but the agency only detailed the process that led to it this week. He has been memorialized on the Courts of the Missing at the National Memorial Cemetery of the Pacific and the Korean War Veterans Memorial Wall in Washington, D.C.
According to the DPAA, the remains of more than 450 Americans killed in the Korean War have been identified and returned to their families since 1982, and about 7,000 Americans are still unaccounted-for from the war.
