This week I am interested in looking up the history of crime scene investigators. I found that the earliest forms of investigations date back to prehistoric times. For example archaeologists uncovered drawings of detailed patterns of hand almost like figure prints.  They would also press hands and fingers into clay or rock. Forensic science continued to evolve in 700 B.C. when the Chinese began to record thumbprints for documents. Later on an ancient Greek physician created the first lie detector test by noting pulse rates. In 1100s with more technology, doctors were able to distinguish between drowning from strangulation.  The text time period of crime scene investigators made  huge advancements with bullet comparisons and developed tissue tests. It wasn’t until the late 1800s and 1900s though was when doctors included technologies like body temperature to determine time of death and fingerprinting for identification. Also in the early 1900s there were portable polygraph machine, voiceprint identification, and DNA analysis.  

            It was surprisingly very easy to find the history of the crime scene investigations. There were many different sources but all of them said about the same thing. I found it very interesting that evidence of forensic science dates back all the way back to prehistoric times. I want to do further research though on what the early people of prehistoric times would do with the fingerprints they collected. I enjoyed researching and being able to see the whole development of crime scene investigations.
