Analyze Bullets Notification For Free

A forensic scientist will examine physical evidence gathered at the crime scene, such as DNA, blood, clothing fibers, tire tracks, firearm residue, drugs, and other chemicals. Then, tests are administered in a laboratory setting to analyze and interpret data so it can be presented in a court of law.

What are the three main types of forensic evidence? There are several types of forensic evidence, but the most common types are DNA, Fingerprint, and BPA.

They take photographs and physical measurements of the scene, identify and collect forensic evidence, and maintain the proper chain of custody of that evidence. Crime scene investigators collect evidence such as fingerprints, footprints, tire tracks, blood and other body fluids, hairs, fibers and fire debris.

This protocol should be used in all crime scenes. Whether the crime scene is a recovered stolen vehicle or a multiple homicide where several crime scenes are involved the basic protocol is the same: INTERVIEW, EXAMINE, PHOTOGRAPH, SKETCH and PROCESS.

Trace evidence can include a wide variety of materials, but the most commonly tested are hair, fibers, paint and glass. Other, less frequently included items are soil, cosmetics and fire debris.

The first step in the Comparison Process is to test fire the firearm into a water tank in the lab. The second step involves using a comparison microscope to compare the test bullet to the bullet recovered from the victim or crime scene.
