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.
