  1. BALLISTICS By, Tate Reed and Matt Lanford

  2. What is “ballistics?” • Ballistics is the study of projectile weapons and their ammunition • This area covers bullets and guns especially • It is the science used to determine things like trajectory, path, speed, “origin,” etc., in our case, of a bullet in a crime scene

  3. Ballistics Categories • Internal – how bullet leaves the gun and begins its projectile path towards its “victim” • Transition – how the bullet is moving and how fast it is moving from initial release • Terminal – how the bullet impacts the target • Determines where it was shot from • The angle of the bullet in the wound • Where the bullet strikes • External – how the bullet flies through the air • wind speed • How external factors affect the flight, etc.

  4. Bullet path: entry & exit

  5. Methods of Investigation • Blood residue on gun • If there is a blood splatter on the gun but not the hand, that rules out suicide • Specific patterns of blood splatter from the bullet can show what angle and how close the shooter was to the victim • A closer look at the bullet • experts look at the marks the bullet made on the gun barrel • The force and trajectory it had leaving the barrel • this is all to tell them what kind of gun was used to narrow down suspects

  6. More Methods: Ballistic Gel • Ballistic gel is used to represent the human tissue • This can tell the investigators a number of things: • flight of bullet through body • Distance and angle from the victim • How certain bullets and guns travel through humans • Speed of bullet upon impact • Can be molded into a human-like figure to recreate the murder victim, and his or her shooting

  7. Interview: Max J. Scott • What methods of investigation do you use? • I graph the bullet nd shooting three demensionally with an X, Y, and Z axis • reverse the path of the bullet hole into the barrel, and determine trajectory • What do you do? • measure the trajectory of the bullet • Examine bullets used in shootings to find type of bullet, gun, and how the bullet flew
