Forensic evidence, or scientific evidence, is an incredibly helpful form of evidence in a jury trial. It often introduces indisputable facts that investigators and forensic professionals prove using scientific methods. Forensic evidence primarily refers to genetic information, such as DNA and fingerprints. It also may include evidence proven by physics and other forms of science, such as ballistics. Its reliability makes it an important factor in whether juries decide to convict or exonerate a defendant in criminal cases.
