- Abstract
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.
