Using the Likelihood Ratio in Bloodstain Pattern Analysis
Type: Publication Research Area(s): Bloodstain,Forensic Statistics
Published: 2021 | By: Daniel Attinger
There is an apparent paradox that the likelihood ratio (LR) approach is an appropriate measure of the weight of evidence when forensic findings have to be evaluated in court, while it is typically not used by bloodstain pattern analysis (BPA)…
Handwriting Identification using Random Forests and Score-based Likelihood Ratios
Type: Publication Research Area(s): Forensic Statistics,Handwriting
Published: 2021 | By: Madeline Johnson
Handwriting analysis is conducted by forensic document examiners who are able to visually recognize characteristics of writing to evaluate the evidence of writership. Recently, there have been incentives to investigate how to quantify the similarity between two written documents to…
Source-Anchored, Trace-Anchored, and General Match Score-Based Likelihood Ratios for Camera Device Identification
Type: Publication Research Area(s): Digital,Forensic Statistics
Published: 2022 | By: Stephanie Reinders
Forensic camera device identification addresses the scenario, where an investigator has two pieces of evidence: a digital image from an unknown camera involved in a crime, such as child pornography, and a person of interest’s (POI’s) camera. The investigator wants…
Forensic Science in Legal Education
Type: Publication Research Area(s): Implementation and Practice,Training and Education
Published: 2021 | By: Brandon Garrett

Psychometrics for Forensic Fingerprint Comparisons
Type: Publication Research Area(s): Implementation and Practice,Latent Print
Published: 2021 | By: Amanda Luby
Forensic science often involves the evaluation of crime-scene evidence to determine whether it matches a known-source sample, such as whether a fingerprint or DNA was left by a suspect or if a bullet was fired from a specific firearm. Even…
Treatment of inconclusives in the AFTE range of conclusions
Type: Publication Research Area(s): Firearms and Toolmarks
Published: 2021 | By: Heike Hofmann
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…
Consensus on validation of forensic voice comparison
Type: Publication Research Area(s): Forensic Statistics
Published: 2021 | By: Geoffrey Stewart Morrison
Since the 1960s, there have been calls for forensic voice comparison to be empirically validated under casework conditions. Since around 2000, there have been an increasing number of researchers and practitioners who conduct forensic-voice-comparison research and casework within the likelihood-ratio…
Commentary on Curley et al. Assessing cognitive bias in forensic decisions: a review and outlook
Type: Publication Research Area(s): Latent Print
Published: 2020 | By: William C. Thompson
In their recent critical review titled “Assessing Cognitive Bias in Forensic Decisions: A Review and Outlook,” Curley et al. (1) offer a confused and incomplete discussion of “task relevance” in forensic science. Their failure to adopt a clear and appropriate…
Estimating Repeatability and Reproducibility with Limited Replications
Type: Presentation Slides Research Area(s): Statistics
Published: 2020 | By: Hina Arora
In many measurement settings, it is important to assess the reliability and validity of measurements. As an example, forensic examiners are called upon to assess the quality of forensic evidence and draw conclusions about the evidence (e.g., whether two fingerprints…
Using Machine Learning Methods to Predict Similarity of Striations on Bullet Lands
Type: Presentation Slides Research Area(s): Firearms and Toolmarks
Published: 2020 | By: Heike Hofmann
Recent advances in microscopy have made it possible to collect 3D topographic data, enabling virtual comparisons based on the collected 3D data next to traditional comparison microscopy. Automatic matching algorithms have been introduced for various scenarios, such as matching cartridge…
Latent print quality in blind proficiency testing: Using quality metrics to examine laboratory performance
Type: Publication Research Area(s): Latent Print
Published: 2021 | By: Brett O. Gardner
Calls for blind proficiency testing in forensic science disciplines intensified following the 2009 National Academy of Sciences report and were echoed in the 2016 report by the President’s Council of Advisors on Science and Technology. Both practitioners and scholars have…
Judges and forensic science education: A national survey
Type: Publication Research Area(s): Implementation and Practice
Published: 2021 | By: Brandon L. Garrett
In criminal cases, forensic science reports and expert testimony play an increasingly important role in adjudication. More states now follow a federal reliability standard, which calls upon judges to assess the reliability and validity of scientific evidence. Little is known…
Using mixture models to examine group difference among jurors: an illustration involving the perceived strength of forensic science evidence
Type: Publication Research Area(s): Implementation and Practice
Published: 2021 | By: Naomi Kaplan-Damary
The way in which jurors perceive reports of forensic evidence is of critical importance, especially in cases of forensic identification evidence that require examiners to compare items and assess whether they originate from a common source. The current study discusses…
Battling to a draw: Defense expert rebuttal can neutralize prosecution fingerprint evidence
Type: Publication Research Area(s): Implementation and Practice
Published: 2021 | By: Gregory Mitchell
The present study examined whether a defense rebuttal expert can effectively educate jurors on the risk that the prosecution’s fingerprint expert made an error. Using a sample of 1716 jury-eligible adults, we examined the impact of three types of rebuttal…
