摘　　要：在各类枪击事件中,跳弹致人伤亡或造成财产损失的情况较常见。在跳弹射击现场,射击弹头和相关痕迹均有不同程度的变形,对痕迹检验和现场弹道分析产生了影响。本文通过对一起因民警在执法办案过程中使用92式手枪射击造成的跳弹现场进行勘查分析,将跳弹痕迹的量化特征引入枪击跳弹分析,对跳弹点痕迹和弹头变形面痕迹的尺寸、形态特征进行检验。该现场跳弹射击过程中,弹头击穿了多层木质客体,通过测量相关客体上射击进出口痕迹和跳弹点的尺寸和距离,准确地计算出跳弹入射角和反跳角,结合现场的布局和距离进行了弹道分析,还原了现场的射击点位置和射击角度等情况,为查明案件性质提供了科学依据。本文为此类事件的调查取证和事件定性提供了参考。In all kinds of shooting incidents,it is more common for ricochet to cause casualties or property losses.At the scene of ricochet shooting,the bullet head and relevant marks have been deformed to varying degrees,affecting the trace inspection and on-site ballistic analysis.This paper investigates and analyzes the jumping bullet scene caused by a police officer’s 92 pistol shooting in the process of law enforcement,introduces the quantitative characteristics of the jumping bullet trace into the gunshot jumping bullet analysis,and tests the size and morphological characteristics of the jumping bullet point trace and the bullet deformation surface trace.During the process of jumping bullet shooting,the bullet head penetrated multiple wooden objects.By measuring the size and distance of the firing entrance and exit traces and the jumping points on the relevant objects,the incidence angle and the rebound angle of the jumping bullets are accurately calculated.The ballistic analysis is carried out in combination with the site layout and distance,and the location of the firing points and firing angle are restored,providing a scientific basis for ascertaining the nature of the case.This paper provides a reference for the investigation,evidence collection,and event characterization of such incidents.
