How is a crime scene analyzed in forensic science?

Forensic scientists in the USA use a systematic approach to analyzing a crime scene. They document and collect evidence such as fingerprints, hair, fibers, and blood samples using specialized tools. Additionally, LaTex and mathematical formulas are used to calculate the trajectory of projectiles and determine the angle of impact for blood spatter analysis. The collected evidence is then processed in a lab using various techniques such as DNA analysis and chromatography to identify suspects. This scientific process allows for the accurate reconstruction of events and the identification of key individuals involved in the crime.
