Non-Identifiable Fingermarks from Unfired Ammunition in Handguns
Listed in Teesside University Research Data Repository
Data Collected as part of National Institute of Justice Award 15PNIJ-21-GG-04192-RESS, Evaluation of the Occurrence and Associative Value of NonIdentifiable Fingermarks on Unfired Ammunition in Handguns for Evidence Supporting Proof of Criminal Possession, Use and Intent.
Description
The overall goal of this project was to answer the question of how often non-identifiable fingermarks occur on naturally loaded handgun ammunition and what range of associative values can be expected.
The datasets include images of 415 Non-Identifiable Fingermarks. The Non-Identifiable Fingermark Dataset has original images in .tif format, whereas the Annotated Non-Identifiable Fingermark Dataset has processed images with annotation of fingermark minutiae. The accompanying spreadsheets contain summary information.

The spreadsheet Marks by Round provides, for each of 1263 rounds of ammunition, the number of identifiable and non-identifiable fingermarks found, the number of annotated minutiae for the marks, the handgun type (semi-automatic vs. revolver) and the caliber class. The spreadsheet Marks by Handgun Load summarizes the results from each of the handguns sampled. The four caliber classes used were 22 (.22LR); 32 (.32 ACP); 38 (including .38 Special, .357 Magnum, .380 ACP and 9mm); and .45 (including .45 ACP, .45 Colt, .44 Magnum and .40 S&W).
