Improving forensic responses to residential burglaries: results of a randomized controlled field trial

Objectives

Residential burglaries (or break and enters) can cause great concern to the public but are typically a routine police job. The present study sought to evaluate an enhanced police approach to this high-volume crime by emphasizing police–victim interactions and more thorough forensic examinations.

Methods

Scenes of crime officers (forensic examiners) were randomly assigned to either a control (business-as-usual) or experimental condition. Officers in the experimental condition received additional training and resources to upskill them in DNA and fingerprint evidence collection and crime scene evaluation. Experimental officers also received additional training on procedurally just approaches to dealing with victims and were encouraged to be more thorough and spend more time at these high-volume crime scenes.

Results

The trial revealed that the enhanced, experimental, approach offered a number of benefits, including greater evidence collection, identification, and incidents solved. Further, this enhanced approach boosted victims’ perceptions of officers’ procedural justice and satisfaction with the procedures used. However, this approach was more costly in relation to time, and the additional collection of extra DNA evidence did not greatly add to the crime solvability of these incidents.

Conclusions

High-volume crimes such as break and enters have a significant impact on the victims and often go unsolved. This study provides causal evidence that enhancing officers’ attendance and attention to victims and evidence at these scenes can increase solvability and enhance victim experiences.
