DNA profiling

Although there isn't always a definite answer on who did the crime, DNA technology has evolved and is a great tool to provide evidence for a case. With that said, DNA alone is not enough to find a suspect guilty or not guilty. DNA is evidence used to determine who committed the crime, how they committed the crime, or if they are innocent. In 1999, in Australia, a girl was raped, and named Frank Button as the criminal who committed the crime. The sheets and pillowcases from where the assault…

DNA fingerprinting is used in forensic science to convict or exonerate a defendant of a crime. During an investigation, crime samples are collected from a scene or from a victim that can be used for DNA testing. Samples could include hair, blood, semen, or skin. After collection, these samples are tested for their molecular characteristics because the purpose is to identify the polymorphic DNA locations of one’s genes. This is because everyone has different genetic variations and can be…

Assessment - DNA Technology DNA Profiling Forensic Identification Forensic Identification refers to the use of forensic science to identify objects from trace evidence found on them. Trace evidence is used to reconstruct crimes or accidents. DNA profiling is a method in forensic science which can identify individuals by their DNA profiles. DNA profiles are encrypted sets of letters that represent a person’s DNA makeup. These sets can be used as a person’s identifier. Although 99.9% of…

There are thousands of jobs that involve chemistry, and some people do not even know it. From something as blatantly obvious as a chemist itself to something in the agricultural field such as an agronomist. It may seem like the two may not have any correlation to each other at all, but both of the careers involve chemistry. Many people see forensic science technicians as some really cool crime scene investigators, but there is so much more to it. Forensic science technicians are crime scene…

forensic science, and everyday there are advancements. Law enforcement officers and forensic technicians have many tools they can work with now, making it a bit easier to help them solve crimes. They have tools for fingerprint analysis, ballistics, DNA typing, and recently forensic phenotyping of simple physical traits such as human eye and hair color. The future of forensic science is bright; tools, gadgets and programs are ever evolving and forensic technicians have taken the advantage to…

There are several ways to find the criminal of a crime. For example, there is testimony, direct, and forensic evidence. But, only one will give the truth of the crime. This type of evidence would give truthful evidence that none of the other evidences can give a person. In the passage “Forensic Science: Evidence, Clues, and Investigation,” by Andrea Campbell, the best evidence to get through a trial is forensic evidence. Forensic evidence is evidence that is found in the crime scene, this…

He/she gathers and investigates information at the crime scene such as physical evidence from the scene. The evidence he/she gathers can range from fingerprints, footprints, hair, blood, splatter, tire tracks, fibers, chemicals, handwriting, drugs, DNA, and broken or bent objects. In this paper I will inform you on what you need to do to study and become a forensic scientist, costs to study it, where/how you can get employed, if you can work independently or not, job descriptions in detail,why…

Triple Jeopardy because finding new evidence, having new opinions, and bringing people long awaited justice can make the difference of a lifetime. Finding new evidence against a defendant is a great reason to have a second trial. First of all, new DNA can be found that directly places someone at a crime scene. Also, there can be new witnesses that could have seen things others have not. With that, witnesses could have been threatened,…

has been involved in law enforcement since 1992. He has been in many positions ranging from undercover narcotics to his current position, detective lieutenant. Between his knowledge and experience he touched on subjects like crime scene procedures, DNA, fingerprints, evidence, analyzing evidence, labs, forensics and other interesting cases he had worked on in the past. Forensic is…

intimidate D.B. Cooper out of attempting this crime again. Technology back then was too underdeveloped to catch a calculated criminal like D.B. Cooper. DNA wouldn’t be used forensically for until nearly 15 years after the hijacking. Had this technology been around, D.B Cooper would be rotting in jail as we speak. Investigators have attempted to obtain DNA particles from evidence, like his tie, but nothing has come of it. The descriptions from the passengers and crew matched for the most part,…
