From the "knot" left at the murderous site, what will the culprit know from the knot until the rope expert guides the criminal?

byRobert Zunikoff

Glenn Dickey, a knot expert, is a person who can understand a number of facts that people do not understand, such as the occupation and nature of the person who connected the string when looking at the knot. He is also active in the field of scientific investigation using that technology, leading to the resolution of crime. What can we learn from 'knot' which can not be distinguished by amateurs? Dickey revealed that.

Dickey belongs to the North American branch of an organization "International Guild of Knot Tyers (IGKT)" ​​by people who love knots. Most people in IGKT devote passion to preserving knowledge of historical and decorative knots, not criminal investigations, and indeed Dickey also said that "knots used in ships of the 15th century" and " Knots that were used in ancient two-wheeled tanks "etc, and I love talking about these things more than anything. However, if ropes are used at the scene of criminal investigation, investigation agencies of various countries are said to contact IGKT for help.

It is said that there are more requests from the prosecution authorities than police for requests for assistance. For example, regarding the murder case of a woman in Michigan in the early 2000s, Dickey was called when the suspect was able to squeeze up to two people, and the judgment of whether the murder occurred was a mechanic or a butcher I was asked. According to Dickey, the murderer tied the victim with the code in the code, but the way to tie the code at this time seems to be a special binding method that people other than the butcher knew first did not know. Furthermore, even from the dominant hand, the butcher seemed to be a criminal. Later, when the police interrogated, the suspect admitted the crime and led to the arrest of the criminal.

Those who commit a crime, even though they are planned, can not think into even a small part. Under extreme stress, the criminal makes a criterion of whether it is "familiar" or not, rather than "how it will affect as evidence." Therefore, the knot will be left with many properties of the criminal, and it will be possible to identify the dominant arm from the winding way of the knot. However, it is also possible for a right-handed person to deliberately make the knot appear to be left-handed, and in this case it will be indistinguishable unless it is an expert.

Dickey, a former writer and editor of the IGKT newsletter, said that when a photograph of the knot remaining on the crime scene was sent from the investigation institution, in the past rope enthusiasts identified "this knot, reproduced I want you to explain, "check the photo of the knot sent and check if there is anything matching the knot left in the crime scene. Also, you can reproduce the knot that was actually left in the crime scene at home and analyze whether there is new discovery or not. Dickey seems to have a nightmare often as these tasks reproduce criminal thoughts with your own head, knowing the fact that loved rope was used for evil purposes. However, Dickey says that Dickey accepts investigative assistance as "obligation" because it will be a situation that "If evil wins by a good person not doing anything," unless you are willing to investigate the crime.

The identification of the knot is not limited to the murder case to be used for criminal investigation. In the invasive robbery that occurred in Florida, the rope was used to bind things, and the knot at this time was very unique. Normally, the way people tie it is limited, and "Semi knot"Stop knot"Longitudinal knotMost of them. In the analysis of 2011, when examining 100 knots in the criminal investigation, there were only 3 to 6 knots that can be called "elaborate". The fact that the knot is "unique" is one of the characteristics of the criminal and the findings of Dickey are important.

Advice to people? Dickey says, "First of all, no one will kill, homicide is not a good idea," plus "If you are concerned with crime, do not get close to the rope, rope leaves too much evidence "Advised.
