Impression Evidence: Strengthening the Disciplines of Pattern and Impression Sciences Through Research

June 2010

Forensic examinations involving specific forensic science disciplines are typically dependent upon qualitative analyses and expert interpretation of observed patterns based on a scientific foundation, rather than quantitative results. These disciplines include latent fingerprints, questioned documents, footwear, and other forms of impression and pattern evidence.

Forensic Biology/Forensic DNA

Forensic Biology/DNA analysis has played a critical role in the investigation and resolution of thousands of crimes since the late 1980s. Over time the forensic biology field has expanded to include techniques that target DNA, RNA, or proteins from all types of organisms and technology has improved in quality, sensitivity, and analysis time.
 

A timeline beginning in 1863 and ending in the 2020s showing the history of DNA and its use in forensics.

Director's Message: Shining Light on Wrongful Convictions

Every wrongful conviction is a miscarriage of justice that impacts every level of our society, often leading to questions about the fairness of the justice system. Wrongful convictions have a life-long impact on individuals who have been wrongfully convicted, the original victims of crime, and their families. To provide the wrongfully convicted an opportunity to prove their innocence through DNA analysis and to  seek justice...
