The use of forensic evidence in criminal investigations has undergone many changes since 1907 when August Vollmer had a biologist analyze blood, fibers, and soil in a murder case. Forensics—the scientific analysis of physical evidence for prosecution or exoneration of individuals in criminal cases—has seen great advances such as the investigation of computer crimes using digital forensics and DNA analysis. DNA evidence has revolutionized criminal investigations and adjudications in attaining exonerations and convictions—providing evidence of identity, with near certainty.
