What Forensic Science Is About

by

When we want to get answers to questions relating to criminal activities and crime related actions, we use forensic science. This involves applying practically wall the knowledge of science in order to be bale to get answers in certain specific crime related questions.

Forensic science is a science that has been changing since its inception around the 212BC and ranges in scope involving the application of natural scientific techniques and procedures to be bale to disclose certain legal and criminal activities.

Since it is a science that is in wide use, people have decided to condense it and call it forensics to show it’s a commonly known and used term that way. In fact it is one word that is being accepted all over from the court to matters that involves the issue of the crime. It truly has spread everywhere for people to use.

It has been even transferred to the dictionary and in fact some of them tend to associate forensics with the original name that which has always been used making it to take over the name of forensic science.

Forensic has a long renown history dating back t the years where we had the roman emperor being one of the greatest rulers, when their was a criminal charge that wanted to confront a group of public peers who were pleading for innocence s they were being accused.

Whosoever gave the convincing evidence either in wording or in speech with at least some physical evidence managed to win the case that is similar to what the prosecutor and the attorney do to our courts today.

When it comes to crime scene investigation (CSI) it mainly involves forensic study and research where the investigator has to gather enough evidence through research and collect enough physical evidence preserve it and use it in court to nail down the accused.

CSI is one field that uses science with other scientific skills borrows from other subjects so that you can be able to gather enough evidence. Together is becomes a force and has information at its fingertips to use at any moment.

The History Of Forensic Science

by

Today our legal system relies heavily and borrows from the Forensic sciences with their various applications to examine evidence and determine the causes and other facts in solving both criminal as well as civil law suits.

The scope of the forensic science has evolved over the years to include several branches that use natural scientific techniques and methods to examine and determine several legal and criminal evidences. It is said that the forensic science as such originate and began to be developed around 212 BC and even as early as 7th century, humans had developed the system of finger printing as unique mark of identification.

Over the years people have begun referring to the field as forensics thus replacing the long phrasing terms. This has now become universally acceptable term and is also used as a misnomer to mean and refer to as a synonym for ‘legal things and legitimate’ phrases.

Since the term forensics has become universally accepted term and is synonymous with criminal field related scientific study, the new phrase has also found a place in the dictionaries where it is mentioned next to the original term.

Forensic science seemed have been developed and used extensively even during the Roman Empire. History records show that an assembly of public peers would be convened to evidence the proceedings of a criminal case where both the accused and the accuser would be given chance to argue their case.

Who ever had the best argumentative, verbose and demonstrative skills and could demonstrate logic based and forensic science based evidence clearly emerged the winner and often it was this skill that led to the victory in legal battles very much like our modern day courts where lawyers and attorneys use their skills to argue the case.

In a way the science of a Crime Scene Investigation as well as forensics study seem to be apparently overlapping and related through very different and distinctive in their final purpose. The role of a Crime Scene Investigator is more to do with discovery, collection, documenting and preserving of physical evidence at site that is later used to present along with evidence as identification in the court to be able to apprehend the perpetrator.

Crime Scene Investigation is a multi disciplinary science that involves both scientific knowledge as well as other areas comprising of logic, law as well as mathematics etc.

Aside from forensic science, this writer also regularly writes about closet shelves and dvd shelves.

Forensic evidence and the key role of the forensic scientist

by

Forensic scientists have a very important role in the criminal process: from initial crime scene investigation to forensic laboratory analysis to providing expert forensic statements and culminating in their appearance in court as an expert witness. Forensic scientists do not just perform forensic analyses and report on the results. As expert witnesses they are allowed to provide opinion as well factual evidence in criminal cases. Interpretation of certain factual evidence and opinions relating to it may vary between forensic experts; which is where forensic defence experts come in to the equation. Many will be extremely experienced and long serving forensic scientists who can use their experience and expertise to re-examine the forensic evidence and peer review any statements from the Crown’s experts. Where appropriate, they can offer alternative forensic expert interpretation and opinion and appear in court as an expert witness for the defence.

Forensic science is divided into several disciplines and most forensic scientists who act as expert witnesses will usually specialise in one or two particular disciplines, which is what makes them ‘experts’ rather than just someone with a general knowledge of forensic science as a whole. These forensic disciplines include Forensic Biology and DNA, Forensic chemistry (which includes marks and traces), Forensic Drugs, Forensic Toxicology, Fingerprints, Firearms and ballistics and Road traffic accident investigation. In many serious criminal cases the trial may involve obtaining forensic evidence from forensic scientists in a whole range of forensic disciplines.

To get a better idea of the role of the forensic scientist let us consider a few case scenarios:

Example case – The crime scene of a violent assault/murder where the victim’s body is still at the scene.

At a crime scene of this nature there may be contact trace exchange, such as blood, DNA, hairs, fibres etc. between the victim and their assailant. This will involve a forensic biologist and necessitate forensic DNA analysis as well as fibre analysis, blood pattern analysis and should also include the examination of the victim’s and suspect’s clothing. All of this forensic evidence can then be interpreted by an expert forensic biologist.

There may be blood stains, smears and splashes, all of which if interpreted correctly by an experienced expert forensic biologist can indicate a possible scenario of what took place at the crime scene before and after the victims death.

There may be fingerprints to be lifted and examined by a fingerprint expert and shoeprints to be photographed and compared by a forensic chemistry expert to shoes found on the person or at the home of a suspected assailant.

It may be that it was suspected that the murder occurred after an argument fuelled by drugs and/or alcohol. Blood samples would then be taken at post mortem and sent to the forensic laboratory for forensic analysis for drugs and alcohol by a forensic toxicologist. The results of these analyses would then be interpreted by a forensic toxicology expert.

In a case of this type there could be several expert witness statements: from a forensic biologist, a forensic chemist, a fingerprint expert and a forensic toxicologist. The content of these statements may or may not be pulled together by an overarching statement from the %u2018lead forensic scientist’ in the case.

Example case – The crime scene of a large scale cannabis cultivation run by a serious organised crime group.

Drugs scenes of this nature are invariably ‘forensicated’ by police personnel (PCs and SOCOs – Scenes of Crime officers). Photographs are usually taken, cannabis plant samples are submitted to the forensic laboratory for forensic examination and forensic analysis and then usually the whole scene is dismantled and all the other cannabis plants are disposed of. This makes the job of a forensic drugs scientist quite problematic as they have to make their interpretation of the scene from photographs and the few sample cannabis plants submitted, with the rest of the forensic evidence having been destroyed.

The role of the forensic cannabis cultivation expert is to identify and analyse the cannabis plants submitted and, based on the photographs and police information about the crime scene to give opinions on the conditions under which the cannabis plants were grown and to estimate the potential yields of cannabis which could have been produced at the scene and ultimately sold. As the information available to the forensic drugs expert is limited, opinions of Crown and defence experts about potential yields can often vary and crucially depend on the levels of experience and expertise of the forensic experts involved. Cannabis cultivation on a large scale is usually a carefully controlled process as any deviation from optimum conditions could dramatically affect potential yields and the monetary value of a crop. It is important to assess plant yields properly as sentencing and asset seizure (under the proceeds of crime act) depend on crop value.

Established and experienced forensic drugs experts engaged by the defence may also be able to estimate crop values, based on their long-term knowledge of drugs markets and the different types of cannabis products sold in them. Original crop values are usually estimated by police ‘experts’.

New York Private detectives and Forensic Locksmithing

by

New York Private Investigators have now adopted a new field known as Forensic Locksmithing. Forensic locksmithing is a relatively unknown field of investigative work that provides a much needed service to law enforcement, government agencies, and private companies. The forensic locksmith, also known as an investigative locksmith, analyzes lock and keying systems for evidence of compromise. This includes determining method of entry, the tools used, the time and skill required, and any evidence that identifies suspects, victims, or other pertinent information. The forensic locksmith does not solve cases; rather they provide information and suggestions to investigators that may enable them to solve a case.
In addition to criminal investigations, forensic locksmiths also perform routine security maintenance for government and private companies to identify any attempts to compromise a lock or key system, successful or otherwise. Many forensic locksmiths also perform penetration testing and security research, too.
In order to become a professional forensic locksmith, one needs to have extensive knowledge of how locks, safes, and keying systems operate and interact with one another. Details of common locks, their features, installation details, and security vulnerabilities are all very important as well.
The importance of understanding compromise techniques is often underestimated. Knowing what can and cannot be used to open a given lock is a priceless skill in any Private investigation because it can drastically reduce the scope to a handful of techniques, and, more importantly, a handful of potential suspects. The forensic locksmith also draws on skills from many other disciplines, including: evidence handling, chain of custody, photography, macro photography, microscopy, and tool mark examination.
One of the primary goals of a forensic investigation is identifying the method of entry; how entry was attempted or accomplished. Forensic locksmiths identify three methods of entry: destructive, covert, and surreptitious. The main difference between each method is the type of evidence left behind and the ease of identifying different attacks.
Destructive entry includes any techniques that damage or destroy a lock, safe, door, window, or wall. Destructive techniques are by far the most common method of attack because of speed, simplicity, and low cost of tools. Most destructive techniques leave the lock or working keys non-functional and are easily identified by both normal users and forensic investigators. Normal users of the lock are the personnel that operate the lock on a regular basis.
Covert entry is not easily identified by users, but can be identified by a qualified forensic cheap private investigator. Common techniques include lock picking, pick guns, vibration picks, key bumping, decoding, and bypass. Most covert techniques do not harm the operation of the lock or working keys. Covert entry techniques are commonly identified by visual inspection of the lock, key, window, or door.
Surreptitious entry techniques cannot be identified by either a user or a qualified forensic investigator. Luckily, few techniques are considered surreptitious, and many that do are expensive or time-intensive. This isn’t always the case; removal and disassembly of almost any lock can be performed quickly and surreptitiously. Visual decoding, such as taking a photocopy of a key or sight-reading the biting cuts on a key, is a simple and powerful surreptitious technique. As a forensic locksmith you must always consider surreptitious techniques as a possibility. In the real world, many of these techniques are eventually identified by non-lock evidence, such as finding a photocopy of the victim’s key in possession of a suspect, hair and fiber evidence left at the crime scene, and so on.
The forensic locksmith provides a valuable service to many organizations, particularly law enforcement and insurance companies. A thorough understanding of locks, safes, and keying systems allows them to provide insight into an often misunderstood area of physical security. Distinguishing between the various methods of entry lets the forensic locksmith quickly identify and categorize both known and unknown entry techniques. With the facts provided by a forensic locksmith, investigators can better focus their efforts on what is important.
