Forensics DNA testing or genetic testing goes back a
century because scientists did not use it before.
They use it now because it developed over the
years and scientists have the ability to perform DNA fingerprinting. DNA Testing Being Used In
Forensics History Of Forensics DNA testing is being used to find someone who committed a crime. Even animals are given DNA test when they're dead to find out if the suspect left any fingerprints. They're also tested because of some those animals can be the ones who killed someone. The Common Methods of
DNA Testing in Forensics The most common methods are fingerprinting, blood testing, shoe prints, and bite marks for DNA testing in forensics. Scientist or detectives use these methods to get any evidence of the person who has committed a crime. It really helps the police or even the family find out who caused the crime. Methods That Are Accessible To The Public In Forensics Methods that are accessible to the public are blocking the people to stay away from the crime scenes. Other methods that are used are DNA testing which help people figure out who's the criminal. DNA Being Collected
In Forensics A little of the DNA is different from one person to another. Scientist use different sample for DNA testing by using blood samples, bone, hair, saliva and body tissues. Everyone has different DNA because of their parents, so it's easy for a detective to spot the person. DNA Testing Guide-
lines in Forensics Some of the testing guidelines in forensics
are how does forensic identification work, identifying people, and how DNA typing done. When type O blood is found in a scene the police might think that it may be an american because 45% of americans have type O blood. In typing done the collect information from the scene and suspect and put everything together to see if it all matches. Pros and Cons *www.newenglandinnocence.org>...>additional resources *library.thinkquest.org/28599/courtroom.htm *www.innocentproject.org * www. nij.gov/topics/forensics/evidence/dna/basics/welcome.htm A Case Example of Forensics Interesting Facts About Forensics Future Hold For
DNA Testing DNA--Green River Killer (1982-2001) A man named Gary Ridgway raped and killed almost 50 women. After he was finished doing his business with them he'll throw their bodies in the green river. He mostly went for the prostitutes in the Seattle area. Police suspected it was him who was doing all this so they got a saliva sample for DNA testing and was put in death penalty. * investigation.discovery.com/investigation/frensics/amaxing-cases/amazing-cases.html pros:
-exonerating the innocent(Helps people get their freedom. )
-identifying individuals(Helps identify people who created crimes. )
cons:
-inconsistent practices(Can make a whole case be worth nothing and let the people who created a crime go free. )
-privacy concerns (The persons DNA is seen by scientist and police.) * www.ehow.com>hobbies& science *www.indy.gov/eGov/country/fsa/pages/home.aspx *www.orni.gov/sci/techresources/humangenome/elsi/forensic.shtml Forensic science fun facts are toxicology, death, evidence, alcohol and drugs. Forensic science is the use of particular information, for example medical and technical skills, to help determine questions in social and criminal courts of law. *www.ehow.com/facts_5999184_forensic-science-fun.html * http://www.ornl.gov/sci/techresources/human_genome/elsi/forensics.shtml The future holds results to crimes people create. DNA testing can be use to get peoples histories and criminal records from the past. This can help people look and see if they would want to hire the person after they viewed their records. Works Cited Page YOUTUBE VIDEO This video is about investigators looking for clues about a lady named Misty. A man was going to check up on his boat that was in the ocean behind his house. When he was looking he saw something strange in the water and leaned down and saw it was a body of a lady. He called investigators so they can get information about what had happen and they found a dog hair on her.
