Criminal investigators use physiological changes and insect development to determine how long a body has been dead, but scientists are using the trillions of microbes involved in human decomposition to find more accurate postmortem intervals.

NIJ-supported research points to the value of targeting multiple social conditions as a strategy for reducing radicalization.

A new postmortem image database will be a resource for research in forensic anthropology, pathology, and radiology.

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 counsel caution on interpreting probationer cognitions — thoughts and thought patterns — as predictors of desistance from crime.

Too often crime victims experience unmet civil legal needs. The Office for Victims of Crime set up a legal assistance network demonstration to help those victims. An NIJ evaluation of the new model returned mixed results.

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 investigated how marijuana affects skills required for safe driving and found that biofluid levels of THC did not correlate with field sobriety test performance or marijuana intoxication, regardless of how the cannabis was ingested.
