Physical Evidence One of the main types of physical evidence is that of our fingerprints. We carry around our own unique maps of swirls and ridges on our fingertips, thus enabling judges and juries to use fingerprints in deciding our innocence and guilt in a court of law (Sealey, 2016). Fingerprints are the most incriminating type of evidence that can be used in a criminal case. Fingerprints are one of the most reliable forms of identification, because no two people have the same…

When a crime is committed the majority of the time the offender leaves behind biological evidence such as saliva, bodily fluids, hair follicles, and fingerprints. The samples are gathered and tested for genetic clues that ultimately identify or exclude who was present at the time the crime occurred. According to Duncan & Daly-Engel (2006), “Asplen & Friedman indicate ‘recent technological advances have made forensic science extremely important in the criminal justice system.” (p.38) Those…

Forensic DNA Analyst Education/Training Required A forensic DNA analyst must at least have a four year degree in biology, chemistry, genetics, molecular genetics, molecular biology, forensic science, physics, criminalistics, and biochemistry. Undergraduates require a bachelor of science in biology, science in biological science, science in forensic science, and a bachelor in molecular biology. You can get these types of education in community colleges (2-4 year colleges), but you would need…

Crime scene investigators “CSIs” go by many names including evidence technician, crime scene technician, forensic investigator, crime scene analyst, criminalistics officer and more. In the past most CSIs were trained police officers. In fact most still work out of police stations today. While CSI professionals collect and preserve evidence from active crime scenes. Forensic lab professionals decipher their findings through DNA testing and other forensic analysis. Crime scene investigators and…

While anthropology is a scientific study of all aspects of human development and interaction, forensic anthropology studies identifying characteristics on the remains of an individual. In other words, anthropology focuses more on culture while forensic anthropology focuses on bones. Analysis of someone’s bones can help in determining the sex, race, age, stature, injuries, and time of death. These factors can link a suspect to a crime and reveal what happened to a person before death (antemortem)…

It is common to hear reports in the media of crimes that have been solved with theassistance of DNA analysis (Brown, 2006). If enough blood, semen or tissue is foundat a crime scene, forensic laboratories can determine the blood type or tissue type byusing antibodies to detect specific cell surface proteins (Campbell et al, 2006). Thismethod unfortunately requires large amounts of fresh samples and is not a strongsource of evidence as several people have the same blood or tissue type and thus…

DNA evidence is a crucial piece of information in a criminal case. DNA evidence is regularly used in criminal cases and is often used as evidence in court, sometimes being the dealbreaker for if someone goes to jail or not. Although DNA is reliable, there are cases where DNA has been tampered with, contaminated, or lost, sometimes wrongly accusing someone who is innocent. Although the use of DNA is still fairly new, it has quickly become the best and most reliable source of evidence in criminal…

Hello I am Michelle Torres a well-known forensic scientist, and I am here to prove that Bob last week murdered Lisa in her own home. I have the evidence to properly prove that my accusation is correct. Hair evidence is very important, it is a timeline that holds a lot of information about a person, like drug use, locations, and dietary information. Analysts are able to tell if individual hairs are human or animal. In our case we are working with human hair, human hair can be tested to…

Conclusions Myskowiak and Doums’ (2003) finding that refrigeration of P. terraenovae can affect the development and biometry of larval specimens after only one day of refrigeration suggests that a common forensic practice could be introducing significant error in to PMI estimations. Furthermore, the different relationships between duration of refrigeration, the stage refrigerated, and the time to development indicate that only L3 larvae return to their standard development rate after…

Blachander, N., N. Babu, Sudha Jimson, C. Priyadharsini, and K. M. K. Masthan. "Evolution of Forensic Odontology: An Overview." Journal of Pharmacy and Bioallied Sciences (n.d.): 1-13. 31 Oct. 2014. Web. 10 Sept. 2016. N. Balachander, N. Aravindha Babu, Sudha Jimson, C. Priyadharsini, and K. M. K. Masthan wrote their article “Evolution of forensic odontology: An overview” about real life examples of how deceased are identified by their DNA. They really emphasized on identifying people by their…
