Violence in Missing and Unidentified Persons Cases

The extent to which violence is involved in missing and unidentified persons cases has not been examined directly, to date, due to a lack of empirical data on the subject. Recently, NIJ- and OVW-funded researchers studied the role that violence may have played in these cases through an examination of key characteristics in the NamUs database.

Aerial Systems for Crime-Scene Reconstruction

New drone-mounted sensing technologies could help investigators reconstruct crime scenes from the air without having to physically enter the space. NIJ-supported researchers evaluated the use of small, unmanned aircraft systems (i.e., drones) for crime scene reconstruction and compared their performance to conventional terrestrial laser scanning. 

From Successful Reentry to Stronger Communities

What is reentry? Why is it important? And what research is being done in this field? National Institute of Justice Journal Editor Beth Pearsall hosts a conversation on reentry with NIJ staff  Senior Science Advisor Angela Moore, Senior Social Science Analyst Marie Garcia, and Social Science Analyst Eric Martin. 

What are Unmanned Aircraft Systems?

Unmanned aircraft system include the unmanned aircraft vehicle, the flight controller on the ground, and the system of communication between the two. In law enforcement, unmanned aircraft systems are used in crowd control, traffic and accident reporting, search and rescue, crime scene reconstruction, pre-operational situational awareness, and even as first responders. 

NIJ’s Term of the Month promotes research-based definitions of criminal justice terms.

Criminal Justice Data Archives

The National Archive of Criminal Justice Data archives data on crime and justice and contains data from over 2,700 curated studies or statistical data series.

Body-Worn Cameras’ Effects on Police Officer Behavior

This practice involves the use of body-worn cameras by law enforcement. The aim of this practice is to record interactions from an officer’s point of view to improve accountability and positively affect police officer behavior

Red-Light Camera Interventions for Reducing Traffic Violations and Crashes

Red-light cameras are a traffic enforcement mechanism that permit police to remotely enforce traffic signals, to deter red-light running at signalized intersections. Red-light cameras are a fully automated photo detection system that includes cameras, sensors or triggers, and a computer.
