NIJ remains a leader within Federal government for forensic science research and development and the Bureau of Justice Assistance will take over administration of all forensic capacity enhancement programs.
We want to assure organizations who rely on these grant programs to support forensics that staff from BJA and NIJ are working closely with one another to ensure a smooth transition. That includes making sure solicitations are posted and grants are made.
All active awards under these programs now will be managed by BJA. All current grantees have been notified of this change. If you are an active grantee and have questions, contact your grant manager.
In fiscal year 2020, all state and local forensic capacity enhancement programs previously administered by NIJ, including most of the programs listed on this page, moved to the Bureau of Justice Assistance (BJA).
We are dedicated to improving the understanding of crime and justice issues through science. Since 2004, NIJ has received annual appropriations for the purposes of various DNA and other forensic science activities. These purposes include support for DNA analysis and laboratory capacity enhancement and support for the forensic science research, development and evaluation that provides knowledge and tools to improve the quality and practice of forensic science and therefore reduce crime and improve public safety.
Each year we consider how to allocate DNA and other forensic activity funds based on needs such as the demand to increase capacity and reduce DNA backlog, NIJ technology working group recommendations, results from studies and new findings, and strategic priorities and perspectives for each of the programs.
The Department of Geography and Anthropology has been offering forensic anthropology services since the late 1970's, with a formal lab being established in the Howe-Russell Geosciences Complex East in the 1990's. Our founder, Mary Manhein, established the FACES Lab in cooperation with Louisiana State University and the State of Louisiana in order to offer expanded services to law enforcement and Coroner's offices.
The FACES Lab offers services such as recovery of remains and assistance in identification, forensic facial reconstruction, DNA collection, inclusion and maintenance of cases in the state repository database, trainings for law enforcement, and so much more.
Our lab works diligently, with the assistance of professional staff, graduate students, and undergraduate students, to provide as much help as possible in the locating of missing persons and identification of unidentified persons so loved ones of these individuals are able to get the help they need.

As an Audio Forensic Expert, knowing what tools are available to me and how they work is extremely important. One type of signal processor that I frequently use is a compressor. While this is often thought of as a tool for music production, it serves many functions in the Audio Forensic lab. Like with most audio signal processors, it takes training and experience to operate compressors properly and effectively when performing a forensic audio enhancement. This experience also helps me determine whether or not the compressor is needed for enhancement.
I will typically use a compressor when certain sounds in a recording are much louder than the rest of the audio and I need to balance the overall volume. An example would be a dog barking occasionally throughout a recording that is peaking much louder than the people talking. Using a compressor, I can attenuate the level of the barking without affecting the level of the people talking. Once the louder signal has been attenuated, I can use makeup gain to increase the overall level of the recording. This becomes extremely helpful when the sound source that needs to be heard is quieter than other sounds. I will often receive recordings where the conversation that needs to be heard is buried or behind another sound source, like a television or even other people in the room. By adding a compressor, I can decrease the difference in the level between the two signals.
Compression is not always the best approach for audio enhancement and in some cases, I avoid using it completely. One of the biggest issues in recordings is a loud noise floor. The noise floor is the sum of all of the extraneous and unwanted noises in the recording. As I mentioned before, sometimes this noise floor is louder than the desired sound and therefore compression helps make the desired signal louder with respect to the noise. In some audio, the noise is already quieter than the desired signal. In these cases, using too much compression can actually increase the level of the noise relative to the desired signal. This can actually make the desired signal more difficult to hear and hurt the overall enhancement.
This is why it takes training and experience to properly use a compressor. With the knowledge that I have gained from my 35 plus years as an Audio Forensic Expert, I know when to use and when not to use a compressor on audio. I also know how to properly use it so that I improve the quality of the audio instead of making it more difficult to hear.
Quick to master, Forensic Enhance allows even novice users to clean difficult material to a standard that would have seemed impossible just a few years ago and, although designed primarily for speech enhancement in the forensic laboratory, it can also be used to clean things such as interviews and reports intended for broadcast that were recorded in particularly noisy environments.

Fingerprints deposited at crime scene can be a source of DNA. Previous reports on the effects of fingerprint enhancement methods have focused mainly on fingermarks deposited in blood or saliva. Here, we evaluate the effects of fingerprint enhancement methods on fingerprints deposited on porous surfaces. We performed real-time quantification and STR typing, the results of which indicated that two methods (iodine fuming and 1,2-indanedione in ethyl acetate enhancement) had no effect on the quantity of DNA isolated and resultant STR alleles when compared to control samples. DNA quantities and allele numbers were lower for samples enhanced with silver nitrate and 1,2-indanedione in acetic acid when compared to control samples. Based on DNA quantity, quality, and observable stochastic effects, our data indicated that iodine fuming and 1,2-indanedione in ethyl acetate were the preferred options for the enhancement of fingerprints on porous surfaces.
This study aimed to implement and evaluate a work-based personal resilience enhancement intervention for forensic nurses. A mixed methods design consisting of surveys, interviews, and a case study approach, whereby the experiences of a group of nurses were studied in relation to their experiences of an intervention programme to enhance personal resilience, was utilized. Nurses working on forensic inpatient wards were invited to participate. Senior nurses were recruited as mentors. Data were collected via pre- and post-programme surveys to evaluate nurses' levels of resilience. Post-programme interviews were undertaken with nurses and mentors to explore their experiences of the programme. Descriptive statistics of survey data examined changes in nurses' resilience levels pre- and post-intervention. Free-text survey data and interview data were analysed thematically. The SQUIRE 2.0 checklist was adhered to. Twenty-nine nurses participated. Levels of personal resilience (M = 4.12, SD = 0.60) were significantly higher post-programme than pre-programme (M = 3.42, SD = 0.70), (t49 = 3.80, P = 0.000, 95% CI = 0.32, 1.07). Nurses felt the programme had a marked impact on their personal resilience, self-awareness, confidence, and professional relationships. The benefits of the programme demonstrate the advantages of providing a nurturing environment for nurses to consolidate their resilience levels. Findings demonstrated that resilience enhancement programmes can increase nurses' levels of resilience and confidence and improve inter-professional relationships. Our findings are important for clinicians, nurse managers, and policymakers considering strategies for improving the workplace environment for nurses. The long-term impact of resilience programmes may improve nurse retention and recruitment.
