The latter, in particular, plays a key role as forensic scientists gather and analyze information that is oftentimes vital to the resolution of the case and the rightful apprehension of the perpetrators. And while these shows make it seem like cases can be solved in a matter of days, the truth of the matter is that forensic scientists use a combination of scientific procedures, medical theories, and apparatuses to unravel the mysteries of a crime scene—an overall process that could take a very long time.
There are a lot of trace evidence that can be gathered from a crime scene. Things like hairs both from humans and animals and feathers, soil, paint, gunpowder residue, carpet fibers, flame accelerants, glass fragments, even pollen grains may be transferred between people, objects, and the environment during a crime.
These things, in turn, can be used to implicate a suspect or find a missing person, among others. Mass spectrometers are used to analyze trace evidence by determining the composition of such substances.
This information can, for instance, lead investigators to a specific location, say a carpet maker who uses a particular mix of dyes or a nearby plantation that grows a specific kind of flower, helping police investigators identify and build a case against suspects.
Another important tool in a forensic laboratory is a microscope, since most of the evidence collected in crime scenes are minuscule and cannot be easily identified or analyzed by the naked eye. With the help of high-powered microscopes, these tiny pieces of evidence can be viewed more clearly and can thus be more easily identified.
The firearm must be collected in an envelope or paper bag. The ammunition and magazine should be gathered in a separate envelope or paper bag. Casings and bullets are collected in paper envelopes or small cardboard pillboxes. If any sharp objects such as knife found, the blade and point must be kept in unmovable cardboard and put in a paper bag or envelope. Hair at the scene can be collected in a paper packet and then put in an envelope. Any more questions? Feel Free to Email Us!

The laser trajectory contains: centering cone laser pointer penetration rods tripod mount Trajectory rods Laser Mirror Protractor Calculator Forensic Lab Equipment There is a wide range of workloads are done in the forensic laboratories including analyzing trace evidence, identifying fingerprints, DNA sample, blood, and hair sample, evaluating body fluids, analyzing drugs or perilous chemicals as well as toxic substances and more.
The instruments commonly used in criminal or environmental forensic investigations and analysis include scanning electron and optical microscopes. These tools are used to characterize forensic evidence like fabrics, metals, textile or glass. They take photographs and physical measurements of the scene, identify and collect forensic evidence, and maintain the proper chain of custody of that evidence.
Crime scene investigators collect evidence such as fingerprints, footprints, tire tracks, blood and other body fluids, hairs, fibers and fire debris. At major crime scenes impressions should be photographed before they are casted. Photography is done first because casting the impression will destroy the original impression and eliminate the ability to photograph the impression afterward.
The object should first be photographed as is, then photographed with the ruler. It could also work on Windows if Ubuntu were to be installed. In the event of a crime, the perpetrators often try to destroy the evidence in order to escape justice. This is an extremely common occurrence in the case of cybercrimes. In such a scenario, it is deleted information on devices that help investigators nab the criminals and restore the damages. Few forensic tools can recover deleted information as well as ProDiscover Forensic.
It lets people know if there have been any changes made to any files or stored data. This wonder tool has the ability to recover just about any data that was deleted from the hard drives of any computer. In addition to that, it can do so in a format that is both secure and admissible as evidence in the court of law.
The remote forensic capability offered by ProDiscover Forensic has been a boon for investigators, which has made it the top choice for hundreds of customers in over 40 countries.
Volatility Framework is a unique forensic tool that lets investigators analyze the runtime state of a device using system information found in the volatile memory or RAM. Whenever we turn a device off, all unsaved data, which is present in the RAM gets deleted. It is only when we save something that it gets transferred from the RAM to permanent memory. In the field of cyber forensics, it often becomes crucial to be able to extract data from the volatile memory in order to find out about recent activities.
So, it goes without saying how useful Volatility Framework has become amongst law enforcement and intelligence agencies, in addition to military and civilian investigators. It is supported by professional forensic experts from around the world and is based on many years of academic research on advanced memory analysis techniques.
It was released at a Black Hat event, which in itself speaks about its status in the international cybersecurity community. Volatility Framework was named among the Top 7 cyber forensic tools preferred by specialists and investigators around the worldHackRead. Developed by Oxygen Forensics, this suite of cutting-edge tools is one of the most effective applications when it comes to gathering information from mobile phones.
In the era of mobile applications, smartphones are almost always vital sources of forensic evidence that highlight the digital paper trail for investigators to follow. Even though the actual crime may have been committed using other electronic devices, the intent and plan to commit the crime may have been discussed and shared among acquaintances.
This is evidence enough to press formal charges and gain leverage in a court of law. And this number is only increasing with each passing year. It is no wonder that the Oxygen forensic Suite has been popular with law enforcement agencies, defense and homeland security organizations, as well as private enterprises. The company that developed this maverick tool, Oxygen Forensics, has over 10, customers in more than countries, which is a testament to its credibility.
It is an easy to use platform offering more than forensic tools that investigators can use to analyze computer memory to discern actionable evidence. It features an interactive GUI and can be installed on flash drives or external hard drives to be used directly without any installation on the required device.
Another world-class forensic tool for the extraction of data from smartphones is Xry. Developed by a company named MSAB, which is a global leader in digital forensics technology, Xry enables investigators to extract actionable information such as call history, SMS, pictures, contacts, etc. Furthermore, Xry is applicable to devices that run on Android, iOS and even Blackberry operating systems.
