利用残缺赤足足迹推算身高

目的由于主客观条件的影响,犯罪现场中常见的足迹多为不完整的残缺足迹,如何能够有效地利用残缺足迹,对案件破获往往具有至关重要的作用。方法从残缺赤足足迹的反映形态出发,选择足迹中明显、稳定的特征点,确定特征量,通过数理统计分析,建立残缺赤足足迹推算身高的经验公式。结果在4个特征量中,跖前缘突点到跟后缘突点的距离与身高的相关性最好,跖内、外缘突点到跟后缘突点的距离与身高具有一定的相关性。结论根据现场残缺赤足足迹的反映情况,也可以近似推断嫌疑人的身高特点,为侦查提供方向。

Estimation of Body Height from Incomplete Bare Footprint

Objective Incomplete footprints are common at crime scenes and the use of such evidence is sometimes important to the investigation.Method The characteristic morphological features of incomplete bare footprints were studied and several stable feature points with high quality were chosen and used for statistical analysis.Linear regression equations were established for the estimation of body height by incomplete bare footprints.Results Among 4 parameters,the distance between the bottom of the heel and the top of the ball margin is best related to the body height,and the distances between the bottom of the heel and the inner and outer point of ball margin are also in good correlation with the body height.Conclusion Incomplete bare footprints can be well utilized in estimating body height and directing investigation by linking the suspect to the crime scene.
