I think that forensic science has been increasingly used by the criminal justice system because the crime rates have gone up in the past 50 years.…
1.I do think that changing technologies make it easier to determine who is responsible for a crime. If it werent for such technologies we wouldnt of been so sure as to who had comittied the crime. We can trace DNA, hair, blood, and shoeprints. We are able to see how they murdered or committed the crime step by step.…
Blood spatter research has become so advanced and is becoming even more high tech on showing how everything went down. This can also help in showing what objects were used when and to do what by their left trace.…
1. The best choice of a technique when blood is found at a crime scene is analyzing the blood. In the genetics laboratory the person who contributes I would say is Alec Jeffreys as he is known as the father of genetic profiling.…
3. Police officers, crime scene investigators and others in the justice system rely on forensic science techniques to ensure that the right people are punished for law violations and to keep people safe. Fingerprints are starting players in the criminal offense and defense lineup. They are so important to criminalistics that justice officers still use fingerprint systems over a hundred years after scientists developed them.…
Criminal Investigation today is being conducted with more technology than ever, due to that we can catch the criminals faster or even close a case, but it wasn’t always like that. Criminal Investigations started with the Bow Street Runners which became the first paid detective unit. As the years went by crime around the world stated to increase, due to that more investigation departments stated developing. One of the most significant person to play a role in today’s police investigations was Allan Pinkerton he was the first detective in Chicago. He was part of the Secret Service and he developed techniques that are still being used in today by police work like the undercover work. After the agency in Chicago was established other agencies started growing around the world more strategies on investigating cases were being develop and were being adapted by other countries. In the 1800 and 1900 Forensic science improved in many ways; know they did not only have the finger printing for evidence but also Ballistic, Forensic Dentistry and serology. Not much after that they developed something that is very big now and days, the computer programs. One of the first programs was the Hitman known today as “The Computer Data Base” used to cross reference information and then they have developed other computer programs that are used by different bureau like the FBI, CSI and other police departments. In today’s society mostly everything is done on computers including they can even recreate a crime scene with the correct measurement and statistic and have a better glimpse of what might have happened. With all that said to me criminal investigation have change throughout the years, but not only to be better at conducting a criminal investigation but following the roots left from the founders of criminology making want they stated a better and…
Answer: A device called the Reflected Ultraviolet Imaging System (RUVIS) aims UV light at areas where fingerprints may be.…
I think the best technique to chose when blood is found at a crime scene is analyzing the blood in a lab. The individual that contributed to modern gnetics analysis is Alec Jeffrey. Alec contributed polymerase chain reaction.…
3. From the survey in the toxicology lab, would you be a good candidate to work in this area of forensic science? Why or why not?…
* New technology- New areas of crime e.g. Computer crime along with new ways of criminal investigation and interrogation i.e. through DNA samples or evidence, blood sample testing. Medical advances including birth technology often raise ethical issues and also create the need for law reform.…
2. Because it helps the criminal justice system when it comes to solving cases. You can’t just have a two person point of view. You need evidence. So forensics helps the criminal justice system to see whose lying and who’s telling the truth.…
1. Why do you think DNA has had such an impact on forensic science? It has allowed us to advance as a society, making it possible to serve justice.…
The use of DNA technology has increased the probability of finding the culprit and also prevents further crimes. Compared to the past, with DNA technology, today “more than twice as many suspects are[were] identified, twice as many suspects are[were] arrested and more than twice as many cases are accepted for prosecution” (Ritter, 2008). This is because of higher availability of DNA sources and uniqueness of DNA. Between two people, 99.9…
The Green River Killer (GRK) was a serial killer in the 1980’s who obtained many victims in the Seattle, Washington area. Since the 1980’s the technology used in criminal investigations have improved tremendously in efforts to aid investigators in their investigations. Some technology advances are in the field of forensic science the study of deoxyribonucleic acid (DNA) and how DNA analysis can tell from what substance(s) a person died from and can link a victim to a killer or a killer to a victim. Also advancement in the Automated Fingerprint Identification System (AFIS) allowed the comparison of thousands of 10-print fingerprints in the system in less than 30 minutes. Another advancement would be in the Forensic Entomology and how insects can help determine the time of death of the victim and if the victim’s body had been moved from a previous location.…
For instance, the history behind how DNA became a reliable tool in forensics goes all the way back to when DNA was first discovered. In the year 1869, a German chemist named Friedrich Miescher first discovered DNA, which he called nucleic acid (Johnson, 2013). However, it wasn’t until 1953 that biologists were finally convinced by Alfred Hershey and Martha Chase of DNA’s importance as the genetic material in organisms (2013). One year later, James Watson and Francis Crick deduced the structure of the DNA molecule. They proposed that it is a double helix with complementary nucleotide sequences (2013). Nonetheless, the most critical development in working towards using DNA in forensics was when Kary Mullis created the Polymerase Chain Reaction in 1983 (2013).…
