This week we were instructed to find two sources of information on the topic we want to learn more about. As I mentioned in the first blog, there are many different fields in forensics. The two I chose are on forensic DNA typing and ballistic fingerprinting.
"Forensic DNA typing is a technique for identifying people from their organic traces – blood, semen, saliva, or hair – and their genetic idiosyncracies. It involves the comparison of small portions of DNA." I think it is very interesting how forensic scientists take something that seems like nothing and figure out whos DNA is at the crime scene. Everyone has a different DNA pattern and everyone's fingerprints are different.
"A ballistic fingerprint is the unique pattern of markings left by a specific firearm on ammunition it has discharged. Ballistic fingerprinting efficacy as a tool of forensics is a matter of some controversy." I am very excited to be able to look at the discharged bullets, analyze the striations, and match the bullets to the gun.
