What is the primary purpose of forensic evidence in a criminal trial?

The primary purpose of forensic evidence in a criminal trial is to physically link the defendant to the crime scene. This type of evidence, such as DNA, fingerprints, or ballistic reports, provides tangible and scientific connections between a suspect and the location where the crime occurred. It serves as a crucial piece of the puzzle for law enforcement and the prosecution, as it can substantiate claims being made about a person's involvement in criminal activity. By establishing this connection, forensic evidence strengthens the case against the defendant and assists the jury in understanding the relationship between the accused and the alleged crime.

While proving guilt beyond a reasonable doubt, verifying witness testimonies, and establishing motive are important aspects of a trial, they do not hinge solely on the scientific and objective nature of forensic evidence like the direct linkage to the crime scene does. Forensic evidence offers a concrete foundation that can enhance the credibility of the prosecution's case as it is derived from a methodical scientific approach, providing a clearer picture of the events surrounding the crime.
