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

“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

Two leading funding agencies renew a joint commitment to evaluate and support scientific activities relevant to criminal justice.

In response to a National Academy of Sciences report calling for more research on the variability of burn patterns, Underwriters Laboratories scientists conducted studies on how ventilation affects fire patterns in residential structures.

Cold case investigations have revealed that, in many cases, those responsible also are responsible for multiple crimes. Therefore, prioritizing cold case investigations can assist in both resolving crimes and preventing future ones.

Identifying individuals through next generation DNA sequencing may involve degraded or mixed samples. A researcher has developed a technique to make fragmented DNA more readable, and a method to help pull individual profiles from mixed samples.

The forensic power of DNA is clear, but biological evidence also contains RNA, another potential source of information. Because RNA decomposes quickly, its utility is considered limited. Could this decomposition provide information about a sample’s age?

The regions of the genome relied on for identification of individuals pose challenges for analysts because they often produce artifacts during processing. NIJ-funded research has led to a solution that lessens the artifact problem.

Key questions have arisen about how DNA data are to be interpreted statistically. Two NIJ grants have supported research that has far-reaching implications for testing hypotheses using DNA evidence and expressing confidence in the conclusions reached.

Forensic scientists have explored whether lifted and archived fingerprints retain forensically useful amounts of DNA.
