BULLET RICOCHET PHENOMENA WEBINAR

Instructor: John Paolucci
Course length: 2 hours


Bullet Ricochet Phenomena Webinar

Students in this two-hour online training course will be instructed to recognize ballistic impact markings from a bullet ricochet, and how to understand and document these markings. Students will be provided with insight into the characteristics that contain important information such as directionality, impact angles, and rifling characteristics.  Students will also be instructed on documenting these bullet ricochet phenomena in notes and photographs.


Course Content:

Hour 1:
​

Students will learn to define bullet ricochet, angle of impact, critical angle, ricochet angle, and angle of deflection.  Students will also gain insight into the conditions that are conducive to ricochet production and the effects of various substrates on ricochet angles.  The following substrates will be discussed: frangible, non-frangible, and curved surfaces.  Students will be exposed to the investigation of bullet ricochet markings on automotive glass to include directionality determinations and rifling characteristics (land and groove identification and collection will be discussed).  Rifling characteristics from recovered bullets and from bullet ricochet impact markings (including the “Chisum Trail”) will be discussed.


Hour 2:

The application of bullet ricochet identification to crime scene analysis and reconstruction will be outlined, including directionality determinations.  The following topics are included: recognition of ricochet crease profiles dependent on different substrates, noting the classic rounded edge impact point, identifying and documenting the Lifting Phenomenon, and bullet destabilization resulting from a ricochet.  The following areas of ricochets will be discussed: painted sheet metal characteristics (such as those found in automotive applications including paint pinch.  Paint fracture lines will be covered including the topside and underside “Christmas Tree” effect.
Additionally, this course will address best practices for data to be included on notes, photographing bullet ricochets, methods for impact angle determination and documentation, and methods for ricochet angle determination and documentation.  The documentation segment will cover bullet ricochet documentation both in notes and in photographs.



This course has been approved for 2 hours of recertification training credits by the IAI Crime Scene Certification Board.
