Advancements In CSI
Overtime advancements in crime scene investigation focused on the aspects of fingerprint detail and chemical elements like poisons. In the mid-1800s, investigators at Scotland Yard began to compare bullets. -
CSI in the late 1800's and early 1900's
During the late 1800s and early 1900s, forensic science started to include technologies like body temperature to determine the time of death and the use of fingerprinting for identification. In 1921 the portable polygraph machine was made. Then in 1933 the gunshot residue tests began to form. -
Modern CSI
With using the information and other technology that was created in prehistoric times, it led to allowing a lot more technology to advance which is why Crime Scene Investigation is the way it is today.
