Hello and welcome back to my blog post. Today, I will answer some questions about forensic scientists.
What is a forensics scientist?
Forensic science plays a vital role in the criminal justice system. Forensic scientists examine and analyze evidence from crime scenes and other locations to provide objective findings. These findings can help in investigating and prosecuting criminals, or they can exonerate individuals who are innocent and under suspicion.
Who was the first forensics scientist?
Archimedes is often considered the first forensic scientist. According to legend, a king had commissioned a special gold crown from a local goldsmith, but he suspected that it might not be made of pure gold. He asked Archimedes to determine whether he had been deceived, but he wanted to ensure that the crown would not be damaged during any tests.
Who was the first person to be convicted due to fingerprints?
The Chinese were the first culture known to have used friction ridge impressions as a means of identification. The earliest example comes from a Chinese document- titled “The Volume of Crime Scene Investigation—Burglary”, from the Qin Dynasty (221 to 206 B.C.).
What is DNA and how is it used to “catch” people – or prove their innocence?
Every individual has unique DNA, except identical twins, who share the same DNA since they originate from the same initial cell. Forensic scientists utilize the distinctive nature of DNA to assist in apprehending criminals.
They collect human cells found at a crime scene, which may come from sources such as blood, saliva, or hair. Forensic scientists then extract DNA from these cells, analyze it, and create a DNA profile.
This DNA profile is compared to a database of other profiles. If a match is found, it can serve as valuable evidence in the investigation.
Genetic profiling can be a controversial topic. The table below summarizes some of the advantages and disadvantages of using this technique.
How does dirt help a forensic scientist?
Soil trace evidence can connect a suspect to a burial site or help establish links between different crime scenes. By comparing soil samples from the burial site with samples collected from other locations, investigators can gain valuable insights into the movements of suspects or objects.
How do insects help a forensic scientist?
From the early stages of decomposition, insects are drawn to the body and may lay their eggs on it. By examining the insect population and the various developmental stages of the larvae, forensic scientists can estimate the postmortem interval, determine any changes in the position of the corpse, and assist in identifying the cause of death.
