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…
Latent print comparison and examiner conclusions: A field analysis of case processing in one crime laboratory
Type: Publication Research Area(s): Latent Print
Published: 2021 | By: Brett O. Gardner
Scholarship on the latent print comparison process has expanded in recent years, responsive to the call for rigorous research by scholarly groups (e.g., National Academy of Sciences, 2009; President’s Council of Advisors on Science and Technology, 2016). Important to the…
A clustering method for graphical handwriting components and statistical writership analysis
Type: Publication Research Area(s): Handwriting
Published: 2020 | By: Amy M. Crawford
Handwritten documents can be characterized by their content or by the shape of the written characters. We focus on the problem of comparing a person’s handwriting to a document of unknown provenance using the shape of the writing, as is…
Statistical Methods for the Forensic Analysis of User-Event Data
Type: Dissertation,Publication Research Area(s): Digital
Published: 2020 | By: Christopher Galbraith
A common question in forensic analysis is whether two observed data sets originate from the same source or from different sources. Statistical approaches to addressing this question have been widely adopted within the forensics community, particularly for DNA evidence, providing…
Psychometric analysis of forensic examiner behavior
Type: Publication Research Area(s): Latent Print
Published: 2020 | By: Amanda Luby
Forensic science often involves the comparison of crime-scene evidence to a known-source sample to determine if the evidence and the reference sample came from the same source. Even as forensic analysis tools become increasingly objective and automated, final source identifications…
Juror appraisals of forensic evidence: Effects of blind proficiency and cross-examination
Type: Publication Research Area(s): Implementation and Practice
Published: 2020 | By: William E. Crozier
Forensic testimony plays a crucial role in many criminal cases, with requests to crime laboratories steadily increasing. As part of efforts to improve the reliability of forensic evidence, scientific and policy groups increasingly recommend routine and blind proficiency tests of…
Statistical Methods for the Forensic Analysis of Geolocated Event Data
Type: Publication Research Area(s): Digital
Published: 2020 | By: Christopher Galbraith
A common question in forensic analysis is whether two observed data sets originated from the same source or from different sources. Statistical approaches to addressing this question have been widely adopted within the forensics community, particularly for DNA evidence. Here…
Implementing blind proficiency testing in forensic laboratories: Motivation, obstacles, and recommendations
Type: Publication Research Area(s): Latent Print
Published: 2020 | By: Robin Meija
Regular proficiency testing of forensic examiners is required at accredited laboratories and widely accepted as an important component of a functioning quality assurance program. Yet, unlike in other testing industries, the majority of forensic laboratories testing programs rely entirely on…
Statistical models to predict exposure settings using two different iPhone camera apps
Type: Publication Research Area(s): Digital
Published: 2020 | By: Kurt Michael Kabriel
The StegoAppDB [Newman, J. (2019)] is a digital image database containing camera data from Android and iPhone mobile phones and developed for forensic purposes. Taken with a custom-designed camera app called Cameraw rather than the camera app native to the…
Statistical methods for digital image forensics: Algorithm mismatch for blind spatial steganalysis and score-based likelihood ratios for camera device identification
Type: Dissertation,Publication Research Area(s): Digital
Published: 2020 | By: Stephanie Reinders
Forensic science currently faces a variety of challenges. Statistically suitable reference databases need to be developed and maintained. Subjective methods that can introduce bias need to be replaced by objective methods. Highly technical forensic methods need to be clearly and…
Bayesian hierarchical modeling for the forensic evaluation of handwritten documents
Type: Dissertation,Publication Research Area(s): Handwriting
Published: 2020 | By: Amy Crawford
The analysis of handwritten evidence has been used widely in courts in the United States since the 1930s (Osborn, 1946). Traditional evaluations are conducted by trained forensic examiners. More recently, there has been a movement toward objective and probability-based evaluation…
Mock Jurors’ Evaluation of Firearm Examiner Testimony
Type: Publication Research Area(s): Implementation and Practice
Published: 2020 | By: Brandon L. Garrett
Objectives: Firearms experts traditionally have testified that a weapon leaves “unique” toolmarks, so bullets or cartridge casings can be visually examined and conclusively matched to a particular firearm. Recently, due to scientific critiques, Department of Justice policy, and judges’ rulings,…
A Pioneer in Forensic Science Reform: The Work of Paul Giannelli
Type: Publication Research Area(s): Implementation and Practice
Published: 2018 | By: Brandon Garrett
Few can say, “I told you so,” to our entire criminal justice system. Being right about what is wrong with the use of evidence in criminal cases is not a bad thing, but being able to influence the growing response…
Probabilistic Reporting in Criminal Cases in the United States: A Baseline Study
Type: Publication Research Area(s): Implementation and Practice
Published: 2020 | By: Simon Cole
Forensic evidence reporting shows a high degree of adherence to prevailing disciplinary standards. Probabilistic reporting of forensic results remains rare. Probabilistic reports were mostly subjective verbal assignments of posterior probabilities.
Statistical methods for digital image forensics: Algorithm mismatch for blind spatial steganalysis and score-based likelihood ratios for camera device identification
