Forensic Science: DNA, Ballistics & Digital Evidence
Forensic science involves applying scientific methods to solve crimes and support legal investigations. Key areas include DNA analysis, which identifies individuals through genetic material; ballistics, which examines firearms, bullets, and their impact; and digital evidence, which involves recovering and analyzing data from electronic devices. These disciplines play crucial roles in law enforcement, government, and public service by providing objective, reliable evidence that aids in criminal investigations, prosecutions, and the pursuit of justice.

❓ Frequently Asked Questions
What is forensic DNA analysis and what can it reveal?
Forensic DNA analysis examines genetic material from crime scenes to identify individuals or determine relatedness. It often uses STR profiling to compare evidence with a reference sample and can link or exclude suspects.
What is ballistics in forensic science?
Ballistics studies firearms, ammunition, bullets, and cartridge cases to determine if a weapon could have fired a given bullet and to match markings between evidence and a suspected weapon.
What is digital evidence in forensics?
Digital evidence comes from electronic devices and includes files, messages, logs, and metadata. It must be collected and preserved carefully to maintain integrity for investigation and court.
What is chain of custody and why is it important?
Chain of custody is the documented record of all people and steps that handled the evidence, with times and conditions. It protects the evidence from tampering and supports admissibility in court.
