NIJ grantee Robert Maher is changing the field of audio forensics with novel techniques to document and interpret gunshot recordings.

Researchers create a metric to determine the difficulty of matching latent and known fingerprints, then link that difficulty to error rates.

Researchers claim they have developed a prototype system that could enable “low-cost, portable, objective analysis of tool marks.”

A sensor technology first developed for medical use is being adapted to detect and visualize destroyed serial numbers in firearms.

Study finds less than 1.2 percent error rate in matching bullets fired from Glock semiautomatic pistol barrels to the actual firearm.
