This source provides a brief history of Forensic Investigation and specifies how and when new forensics ways were discovered and the purpose of them. It states that in 1953 DNA was said to have unique structures, which was discovered by Watson and Crick. Then, the author goes into detail about how the restriction fragment length polymorphism and polymerase chain reaction testing was used to identify suspects as well as victims by their DNA. This process was called DNA fingerprinting and was first used in a case that went to trial in 1987. By 1989 DNA was proved to be valid and

It provides reliable information based on real-life cases and is posted on a Forensic Colleges website. These cases were solved by confession, the re-examination of clues, or by new forensic technologies that were developed over the years. I will be able to use this source because it provides some cases that were solved by DNA, which is what my research is on. For example, the case in 1995 where a seventeen-year-old was murdered by being hit in the skull was solved after a new forensic vacuum was developed and able to collect DNA on the rock that was used as the murder weapon. The DNA collected from this rock was matched to a bus driver in the same area, which then led to his arrest. This article also provides other cases solved by DNA which are great examples of how DNA has made an impact on solving major …show more content…
While answering why backlogging exists the author goes to show the efforts that are being made to lessen the backlog quantity. The author explains the different between the casework backlogs and the convicted offender/arrestee backlogs, which are known to be faster. Next, it goes to talk about how scientific advances, along with other reasons, is increasing the demand for DNA testing. It provides examples of backlogged DNA testing from rape kits to DNA taken from convicted offenders. It’s credible as it seems to show statistics on the number of old and new backlogged testing. It will tie in very well with my paper as I am aiming to write about the negative effects of DNA testing as well as the positive impact it has with
