Criminalistics is the field dedicated to determining the perpetrator of a crime. It encompasses the examination of physical evidence such as blood, bullets, and other items discovered at the scene of the crime. Scientists employ specialized tests to analyse the evidence and unravel the sequence of events. It is important to note that criminalistics differs from criminology, which focuses on understanding the motives behind criminal behaviour.
Criminalistics refers to the scientific examination of physical evidence in order to detect and solve crimes. This involves conducting laboratory tests on items such as bullets, blood, and tissues. It is important to note that criminalistics is distinct from criminology, which focuses on the study of criminal behaviour. For instance, in cases where a gun is used in a crime, criminalistics can assist in determining if the bullet recovered from the scene matches the gun. By analyzing the unique markings on the bullet and comparing them to the gun’s barrel, criminalists can establish whether the gun was indeed used in the crime. Similarly, if a suspect’s DNA is discovered at a crime scene, criminalistics can aid in determining if it is a match. Through the analysis of the DNA sample and its comparison to the suspect’s DNA, criminalists can ascertain whether the suspect was present at the crime scene. These examples effectively demonstrate how criminalistics employs scientific methods to analyse physical evidence and contribute to the resolution of criminal cases.
