Multidisciplinary Team Works to Reduce Preventable Deaths of Older Adults
How Good Are the Data? Novel Metric Assesses Probability That an Unknown Drug Sample Matches a Known Sample
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.
Forensic Laboratory Needs Technology Working Group — A Channel to Improve Forensics
How Things Burn: Developing Realistic Models of How Materials Combust and Degrade in a Fire
Researchers have created a more accurate methodology for predicting how things burn
Crime Scene Documentation: Weighing the Merits of Three-Dimensional Laser Scanning
The reliability, interpretability, and cost-benefit of three-dimensional laser-scanned images for crime scene documentation is assessed.
Improving the Collection of Digital Evidence
Two NIJ-funded projects introduce new methods and tools for collecting and processing digital evidence in cases involving child sexual abuse materials and large-scale computer networks.
The Search for a Microbial Death Clock
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.
Algorithm Quantifies What Experts See When They Examine Skeletons
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.
The Forensic Microbiome: The Invisible Traces We Leave Behind
“Wherever he steps, whatever he touches, whatever he leaves, even unconsciously, will serve as a silent witness against him.” Edmond Locard (1877-1966), forensic science pioneer
Genetic Variants Linked to Sudden Unexplained Deaths
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.
New Method for Measuring Human Decomposition Could Significantly Impact Medicolegal Death Investigations
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.
Field Sobriety Tests and THC Levels Unreliable Indicators of Marijuana Intoxication
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.
Fast and Portable Drug Testing: Dual-Method Prototype Shows Promise for Court-Admissible Drug Testing
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.
