Criminal Investigations Past and Present Lakesha Wilson Everest University In what ways have our historic roots affected the manner in which criminal investigations are conducted in the United States today? FBI agents have been around since 1908. This happened during the presidency of Theodore Roosevelt. An attorney by the name of Charles Bonaparte came up with getting special agents together to form this team. The two men first met when they both spoke at a meeting of the Baltimore Civil Service Reform Association.
In 1970, the Federal Bureau of Investigation developed a computerized automated fingerprinting system, called AFIS, which is still in use today. Sir Alec Jeffreys developed the first DNA profiling technique in England in 1985. Fhe FBI's combined DNA index system, or CODIS, which allowed different crime labs and departments to share DNA information, was created in 1990. In the early 2000s, the Scanning Kelvin Probe was developed by scientists at the Swansea University in the United Kingdom. The probe uses electric voltage to "see" latent fingerprints, even on surfaces that have been wiped
1. What was Francis Henry Galton's major contribution to forensic science? Henry Galton’s major contribution to forensic science was that he took the first definitive study of fingerprints and developed a methodology of classifying them for filing. He wrote a book called fingerprints that contained proof to his method. 2. Who is known as "the father of forensic toxicology" and why?
Through the four steps of the scientific method an investigator can put the pieces together and solve the investigation in a thorough and complete fashion. A criminal investigation refers to the process of collecting information (or evidence) about a crime: (1) determine if a crime has been committed; (2) identify the perpetrator; (3) apprehend the perpetrator; and (4) provide evidence to support a conviction in court (JRank, 2010). These four steps would be how the scientific method would fall into criminal investigations. This can be taken into consideration as to what investigators used when trying to identify and solve the Green River Killings in the Seattle and Tacoma, Washington area between
Robert Hooke's most famous scientific work was his book Micrographia, which he published in 1665. This book is a collection of observations from his homemade compound microscope and illumination system. He observed not only plants but also many types of life from insects, sponges, and microorganisms all the way up to bird feathers. In conclusion, Robert Hooke was probably the single greatest experimental scientist to come out of the seventeenth century. He was one of the most diverse of all scientist of his time contributing major findings to almost all fields of science.He was an natural philosopher, architect and polymath who played an important role in the scientific revolution, through both experimental and theoretical work.
Without this device, the identification of toolmarks and firearms would be such a cumbersome process that it would be carried out on a very limited basis. (Lerner, 2005,World of Forensic Science, Encyclopedias) History Chemist Philip O. Gravelle and American Army Colonel Calvin Goddard were the pioneers who invented the comparison microscope in 1921. At that time the comparison microscope was used to compare fired bullets and casings because of the unique impression left on the fired bullets or cartridge case. Calvin Goddard Calvin Goddard perfected the comparison microscope and subsequently popularized its use. Comparison microscope was first introduced to the European scientists for firearms identification and other forensic uses by Sir Sydney Smith (Thorwald ,1964,wiki,) In the late 1920s, Swedish criminalist Harry Söderman drastically improved the comparison microscope by inventing a system for rotating the bullets under the objectives.
According Bio. True Story (1994-210), “Allan Pinkerton was born on August 25th 1819 in Glasgow Scotland and died July 1st, 1884.

Most psychology classes always talk about criminal behavior and it has been a debate dating back to one of the founding psychologists, Sigmund Freud.

Another topic in psychology classes is talking about how psychologist in the early 19th century thought that behavior like this was genetic and could be passed down and inherited through each generation.
It gives citizens an opportunity to search the latest information for the identity and location of known sex offenders. It lets them search for sex offenders from all 50 states, the District of Columbia, Puerto Rico, Guam, and numerous Indian tribes. The FBI laboratory is focused on solving and preventing crime with new science and technology. The first crime lab for the FBI came about in 1932. There are over 500 scientists working in the facility in Virginia.
