Advancing the Understanding of 3D Imaging for Firearms Identification
Type: Presentation Slides Research Area(s): Firearms and Toolmarks
Published: 2024 | By: Melissa Nally
Houston Forensic Science Center, in collaboration with CSAFE, has been awarded an NIJ grant to conduct a study focused on comparability of images acquired by 3D instruments manufactured by different vendors. The vendors participating in this study are Cadre (TopMatch),…
Computational Shoeprint Analysis for Forensic Science
Type: Dissertation Research Area(s): Footwear
Published: 2024 | By: Samia Shafique
Shoeprints are a common type of evidence found at crime scenes and are regularly used in forensic investigations. However, their utility is limited by the lack of reference footwear databases that cover the large and growing number of distinct shoe…
Score-based Likelihood Ratios Using Stylometric Text Embeddings
Type: Poster Research Area(s): Forensic Statistics,Handwriting
Published: 2024 | By: Rachel Longjohn
We consider the problem setting in which we have two sets of texts in digital form and would like to quantify our beliefs that the two sets of texts were written by the same author versus by two different authors.…

Algorithmic matching of striated tool marks
Type: Presentation Slides Research Area(s): Firearms and Toolmarks,Forensic Statistics
Published: 2024 | By: Yuhang Lin
Automatic matching algorithms for assessing the similarity between striation marks have been investigated for bullet lands and some tool marks, such as screwdrivers. We are interested in the investigation of how well tools can be identified by marks left on…
Silencing the Defense Expert
Type: Presentation Slides Research Area(s): Forensic Statistics,Implementation and Practice,Training and Education
Published: 2024 | By: Jeff Salyards
In the wake of the 2009 NRC and 2016 PCAST Reports, the Firearms and Toolmark (FATM) discipline has come under increasing scrutiny. Validation studies like AMES I, Keisler, AMES II, Best & Gardner, and Guyll have provided important information about…
Developing a Repeatable and Reproducible Protocol for Establishing Combined Minutiae Frequencies
Type: Presentation Slides Research Area(s): Latent Print,Training and Education
Published: 2024 | By: Adele Quigley-McBride
Fingerprint minutia types influence LPEs’ analyses and evaluations during casework, with features perceived as rarer generally given more weight. Last year, we reported on examiner perceptions of minutia type frequency. This year, we present the next phase of our research.…
A reproducible pipeline for extracting representative signals from wire cuts
Type: Conference Proceeding Research Area(s): Firearms and Toolmarks,Forensic Statistics
Published: 2024 | By: Yuhang Lin
We propose a reproducible pipeline for extracting representative signals from 2D topographic scans of the tips of cut wires. The process fully addresses many potential problems in the quality of wire cuts, including edge effects, extreme values, trends, missing values,…
An algorithm for forensic toolmark comparisons
Type: Publication Research Area(s): Firearms and Toolmarks,Forensic Statistics
Published: 2024 | By: Maria Cuellar
Forensic toolmark analysis traditionally relies on subjective human judgment, leading to inconsistencies and lack of transparency. The multitude of variables, including angles and directions of mark generation, further complicates comparisons. To address this, we first generate a dataset of 3D…
