Forensic handwriting analysis relies on the principle of individuality: no two writers produce identical writing, and given enough quality and quantity of writing, it is possible to infer whether two documents were written by the same person.

In the past decade, and in response to the recommendations set forth by the National Research Council Committee on Identifying the Needs of the Forensic Sciences Community [2009], scientists have conducted several black-box studies that attempt to estimate the error rates of firearm examiners.

We will describe two recent experiments. In the first, we conducted two studies whether knowledge of an expert’s performance on blind proficiency testing affects trust in the expert witness, the evidence (fingerprint or bitemark), and verdicts.

Blind proficiency testing is a norm or requirement in many scientific fields. However, forensic laboratories primarily rely on open proficiency tests from vendors such as Collaborative Testing Services, Inc. or Forensic Assurance. In open proficiency tests, examiners know they are being tested, and the test targets a specific step in the evidence handling and analysis pipeline.

Shoe outsole prints are often found in crime scenes. If a suspect is apprehended and her shoes are potential sources of the prints in the crime scene, how might a forensic scientist go about quantifying the degree of similarity between the two?

In this two-part presentation, we will focus on aspects of the forensic identification of source problems where the main question of interest is determining the origin of evidence with unknown source.

Every stake holder claims dominion over the reconstruction of a violent event (detectives, attorneys, scientists, trier-of-fact), yet most have nothing but common (non)-sense and parochial experience to guide their efforts.
