The Forensic Scene
With all of the new forensics techniques today and having emerged in the early 20th century, law enforcement discovered that it needed a specialized team to analyze evidence found at crime scenes. This is the forensic team. By the ending of the 20th century, forensic scientists had a wealth of high-tech tools for analyzing evidence from DNA analysis, to digital fingerprinting techniques with computer search capabilities and other high technological methods.
Forensic science goes back thousands of years. One of the first applications discovered and used was the fingerprinting method. This stemmed from the ancient Chinese people that they used to identify business documents. A man named Sir Francis Galton was the first to establish the first system for classifying fingerprints back in 1892. The Henry Classification system came about for the standard for criminal fingerprinting used worldwide. Sir Edward Henry developed this in 1896 based on the flow and pattern of fingerprints.
In 1836, a chemist named James Marsh developed a chemical test to detect arsenic. This was used during a murder trial during this time. In 1930, a scientist named Karl Landsteiner won the Nobel Prize for classifying human blood into its various groups. This work done by Landsteiner paved the way for future use of blood in criminal investigations. Other tests were than developed in the mid-1900s to analyze saliva, semen and other body fluids as well as to make blood tests more accurate and on point.

A man named Henry Goddard was the first to use the physical analysis in 1835. He connected a bullet to the murder weapon, which we can so easily do today. From here, bullet examination became more precise during the 1920’s. This stemmed from the microscope being created by Calvin Goddard. During the 1970’s, a team of scientists in California, than developed a method for detecting the gunshot residue using scanning...
