Forensic science has come a long way throughout the centuries. In fact, it is only recently that is has become so extensive. There is no record of exactly when forensic science began. “Until the 1960s, the police did not fully utilize forensics and preferred ‘good old detecting’.” They were mostly interested in clues they could see and touch. However today’s detectives are much more interested in evidence they cannot see with the naked eye. This is why forensic science requires a fairly large amou

Unquestionably, forensic sciences and the studies of evidence left at a crime scene have greatly involved science in the solving of mysteries and crimes. Sciences have definitely played a big role in today’s existence. It began a very long time ago, but it is still but the beginning of the researches and developments. With technology still very active, who knows what will happen in the near future with forensic investigations.

Whenever you enter a room, you carry something into that room with you. Criminals may try to hide their identity by wearing gloves or masks. However, whenever you leave a room, something will be left behind. It could be biological evidence such as a hair or fingerprints or non-biological like a fiber or a spec of paint. Scientists need to know what the evidence is composed of, where it came from and who brought it to the scene. Many crimes are often involved with firearms and bullets. A bullet found in a victim can be traced to the gun that fired it, and from the gun, to the killer who pulled the trigger. During the firing, bullets spin rapidly because of the grooves in the barrel of the gun. This spinning effect leaves marks of the grooving and after the bullet is shot, gunpowder stains may be found on the bullet itself. Because each gun is different, all marks and gunpowder stains on the bullet are what make it identifiable. From there, the stores where the gun is sold are traced. From that point on, the suspect can be convicted. The angle of penetration that the bullet suffered may also provide evidence. It can conclude how the gun was shot, for example sometimes the angle of the shot proves that it is not possible for a person to have committed suicide. Other helpful evidence that may not seem like much is threads and fibers. “The objective of forensic investigators is to link fibers from an unknown source to a known source and then figure out how that connection took place.” Each clothes manufacture will often keep a photographic record of the types of fibers it used, and the forensic team has access to these. Microscopic examination of cut rope fibers can reveal if the rope was cut with a sharp object or cut by rubbing against a rough edge. It may even go as far as detecting if a left or right-handed person cut the rope. Chemical studies of the oils left on the fibers can sometimes even reveal who was wearing the specific clothing of article or who handled the rope. Another very interesting evidence that is often used is bugs. “Insects are the first to arrive at a dead body.” “They [insects] hold the
