Forensic identification

A coroner is someone who examines dead bodies and sees what caused that person to die. Some interesting things about the Grundy County Coroner, (John W. Callahan) is that he examines the fingerprints and x-rays of the dead body and he looks at the DNA records with the fingerprints and he takes all of this to the law agencies to see what they can do with it to see how they actually died. First, John Callahan when he works on 24 hours a day, 7 days a week getting calls at his office for Union…

Latent fingermark being imperceptible to the unaided eye is the decisive form of physical evidence found on divergent surfaces at the scene of crime. It is decisive because of its perpetuality and uniqueness. The word ‘fingerprint’ is common in commonality but individual to a person. When a person grasp something, he left the traces of residues (secretions of glands) conforming impression of the ridges of the fingers. The fingermark residue is a complex matrix of secretions and xeno-materials.…

The duality of Forensics Forensic science is the application of natural science to matters involving the law. Forensic science consists of many branches, and though they all differ, they relate in the aspect of their attempts to find out the truth in a criminal investigation, But just how effective and reliable is forensic science? And if effective, is it for better or worse? Of course, opinions on this vary greatly. Here’s mine. The good It can be accurately claimed that forensic science…

A big concern around the collection and analysis of digital evidence is when an executed search warrant becomes a general warrant. Digital evidence is scattered within a computer surround by data that is considered to be protected documents. Because of this fact digital evidence collection and analysis can turn a warrant into a general warrant. This is a major problem for law enforcement because it means that whole cases could be thrown out, or criminals could end up back on the street. Many…

Forensic scientists are crucial for the criminal justice system because their work has a major effect on criminal cases. They can solve and link a suspect to a crime. It is imperative that forensic experts work with high proficiency. The testimony of a forensic expert can influence a jury’s point of view and help the defense team or the prosecution. A mistake can cause false accusations or exonerations. Forensic scientists must have strong verbal and written communication skills. They have to…

“Burked,” one of the featured analysts was a forensic entomologist. Forensic entomologists apply their knowledge of insects to a variety of investigative purposes, such as estimating the time since a person has died (Investigating Forensics). Forensic entomologists can also apply their knowledge to establish a connection between the victim and a suspect, or to determine the geographic location of the victim’s death. Other responsibilities of forensic entomologists include studying the climate of…

Escobar brothers were the ones who had committed robbery in various towns. One of them, Jorge Escobar, was my grandfather. This type of heinous crime where three innocent men died is the reason why I am a Forensic Scientist and ultimately shaped my decision to obtain a Master’s in Chemistry. Forensic Science is any natural science or physical science, like chemistry, that is applied to the law. Hearing about my grandfather’s death pushed me to focus on a career where I can serve justice for…

I was able to find several examples of court cases involving digital evidence and its admissibility in court, but the search for specific cases involving searches of seized or suspect digital media was little harder to come by. The laws have changed drastically over the last decade as digital information has become more prevalent in our daily lives. For example, most important court decisions involving digital searches happened within the last five years, which is just crazy considering digital…

Forensic chemistry is the application of chemistry to provide information for use in courts of law or in public discussion and debate. It is a special branch of chemistry that is concerned with identifying the substances present in samples. A forensic chemist analyses predominantly biological samples such as blood, saliva, and semen (of which all contain DNA, proteins and amino acids) that are brought in from the crime scenes and reaches a conclusion based on tests run on that piece of evidence.…
