摘要

即使有证据表明失踪人员的最后下落,由于在室外环境中难以识别骨骼,许多人类骨骼遗骸的搜索和恢复行动也不成功。虽然已知骨骼的胶原蛋白成分会发出荧光,但在骨骼遗骸搜索过程中,这种特性并没有得到一致的利用。与弗吉尼亚州应急管理部有关的志愿者在东部落叶林中5000平方英尺的区域内完成了36次模拟搜索。猪和鹿的骨头分散,部分隐藏在灌木丛和树叶的覆盖下。两组志愿者被允许以他们通常的模式进行长达1小时的搜索。夜间搜索使用手持交替光源(ALS)设备(uvBeast™,Crime-lite®,ForenScope和Labino AB)进行,产生紫外线(385-395 nm),紫色(395-425 nm),蓝色(~ 4555 nm),青色(~510 nm)或绿色(~530 nm)光。滤过的安全眼镜与合适的ALS配对。白天的搜索在相同的参数下进行,没有ALS。结果表明:(1)夜间搜索ALS患者的恢复率是白天搜索的三倍以上(p®),由于照明的宽度和荧光响应的强度,始终产生最高的恢复率(95%)。数据表明,ALS患者的夜间搜索既可以作为定位和恢复人类骨骼遗骸的主要搜索方法,也可以作为恢复任何预计存在但在白天搜索中未发现的骨骼的次要方法。

Assessing the effectiveness of alternate light sources in the search for skeletal remains.

Many search and recovery operations for human skeletal remains are unsuccessful due to difficulties recognizing bones in outdoor environments even when evidence indicates the last known whereabouts of missing individuals. Though the collagen component of bone is known to emit fluorescence, this property has not been leveraged consistently during skeletal remains searches. Thirty-six mock searches were completed in 5000 ft2 zones of eastern deciduous forest by volunteers associated with the Virginia Department of Emergency Management. Pig and deer bones were scattered and partially concealed under brush and leaf cover. Pairs of volunteers were allowed up to 1 h to conduct searches in their usual pattern. Nighttime searches were conducted with handheld alternate light source (ALS) devices (uvBeast™, Crime-lite®, ForenScope, and Labino AB), which produced ultraviolet (385-395 nm), violet (395-425 nm), blue (~455 nm), cyan (~510 nm), or green (~530 nm) lights. Filtered safety glasses were paired with appropriate ALS. Daytime searches were conducted under the same parameters, without ALS. Results indicated that (1) nighttime searches with ALS produced a recovery rate more than triple that of daytime searches (p < 0.0001) and that they were often completed more quickly, and (2) the violet Crime-lite®, due to breadth of illumination and strength of fluorescent response, consistently produced the highest recovery rate (95%). Data suggest that nighttime searches with ALS can be used both as the primary search method for locating and recovering human skeletal remains, and as a secondary method for recovering any bones expected to be present but not found during daylight searches.
