NIJ-funded researchers developed a novel metric to assess probability that an unknown sample of a drug matches a library sample, with profound implications for standardization of mass spectrometry results.

Researchers have created a more accurate methodology for predicting how things burn

The reliability, interpretability, and cost-benefit of three-dimensional laser-scanned images for crime scene documentation is assessed.

Development of blowflies on a body is a standard forensic measure of time since death, but temperature variations can alter that development and mislead investigators.

Researchers believe a bacterium that causes food poisoning and other diseases may underlie some SIDS cases.

New drone-mounted remote sensing technologies could complement conventional ground-based laser scanning in efficiently recreating crime scenes for forensic analysis.

Researchers created an open-access computer program for estimating the age of skeletal remains that outperforms current methods. The algorithm is based on 20 age-related skeletal changes identified by experienced forensic anthropologists.

Researchers improve molecular autopsy accuracy by identifying more genetic variants that could lead to sudden unexplained deaths. These genetic clues may better inform criminal investigations and help prevent deaths in surviving family members.

Improving postmortem interval estimation with standardized and simplified protocols could significantly impact medicolegal death investigations by providing more accurate and reliable data for determining time since death.

Researchers integrate two independent, validated drug-testing techniques – mass spectrometry and Raman spectroscopy – onto a single platform prototype for fast and accurate analysis of seized substances.
