Forensic investigators now have more information on the performance of identification technologies for biological fluids.

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.

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

Scientific inquiry into the process of decomposition has studied a wide range of mammals and developed a fundamental understanding of the stages of decomposition, but forensic scientists should use caution in applying nonhuman data to human bodies.

Two researchers with a long record of research into the forensic value of very small particle populations examined cell phones, handguns, drug packaging, and ski masks from the San Diego County Sheriff’s Office to determine if such particles can make phys

One influential scientist reflects on the pivotal role that NIJ funding has played during his prolific career in forensic science.

NIJ-supported researchers are using oxygen and strontium isotopes to help law enforcement identify victims.
