Shot in the Dark™ Bullet Striations

When a bullet is found at the scene of a homicide, your students must examine it to discover more details about the events surrounding the murder.



Bullets recovered from crime scenes can identify the type and manufacturer of the weapon that fired them, what the bullet hit before being found, even the specific gun used in the crime! With this kit, your students will attempt to determine which firearm fired the bullet found at the scene, information that could help them identify the murderer.
