Electronic Presentation of Evidence (EPE) enables both digital and traditional forms of evidence to be presented in an easily understandable format and has been proven to help jurors understand and retain information to a greater degree leading to better judicial outcomes. Significantly the use of EPE has also been proven to make up to 30% cost savings in trials.

In 2005 the Lord Chief Justice issued a protocol regarding Complex cases likely to last more than 4 weeks. “Electronic Presentation of Evidence has the potential to save huge amounts of time in complex criminal trials and should be used more widely……effectively managed, the savings in court time achieved by EPE more than justify the cost”


“I would like to commend and thank those who were responsible for the presentation of the evidence by electronic means which made clear and concise presentation a reality rather than a dream”


Evidential are highly acclaimed specialists in the field of Electronic Presentation of Evidence, having provided expertise in high profile cases in the UK Criminal Justice System and for the United Nations and the International Criminal Court.

Not just a court tool

Bcause EPE’s enable better visualisation of complex data and information they can be  used during the investigative stage to:

  • Evaluate large or complex data sets
  • Visualise timelines and order of events
  • Aid witness interviews

Will my case benefit from EPE?

YES, if any of the below are present:

  • The trial is listed for 4 weeks or more
  • A not guilty plea is indicated
  • Significant amounts of evidence; 4000 pages of information or more
  • Complex to present or understand evidence
  • Very high cost cases

Bespoke to your needs

We work closely with you to ensure the EPE meets your exact needs including your budget. Each one is bespoke tailored to ensure the evidence is presented in the most understandable and user-friendly format. Each EPE can include various elements and we will undertake a free assessment of your evidence and provide advice to to help you get the best results and value for money.

Your EPE could include:

video edit


Displaying key video images and key sequences, clearly demonstrating what took and place the sequence they took place in. Footage from various sources can be compiled to show the flow of an event or various viewpoints to provide clear understanding of a crime scene.


Reconstructions allow a greater spacial understanding of an incident scene. They can be simple 2D plans or full interactive 3D models allowing you to virtually move through the scene and view it from witness view points, help prove or disprove testimonies. The location of key pieces of evidence can be clearly demonstrated providing context to the events that took place.

Animations can be used to sanitise graphic and potentially distressing events or used to demonstrate an event clearly, displaying the sequence of the events and actions taken. They are invaluable for presenting difficult to explain information such as injury mechanisms, ballistic trajectories and complex theories.


The searching of large paper bundles is time consuming and makes it difficult to both understand and retain relevant information. The digitisation of documents into an e-bible enables easy and speedy searching, annotation and highlighting of key information including zoom functions and the comparison of documents through overlay or side by side comparison.



Digitisation is not just confined to document bundles, it can be used to convert various difficult media formats into standardised formats to enable better demonstration within court or during the investigation stage. Digitisation can enable searching, annotation and improved viewing through zooming and enhancements.

Crime Scene Surveying & Reconstruction

Crime scene surveying can be done through traditional surveying techniques or via modern 3D laser scanning. 3D laser scanning allows insights of unrivalled detail into any scene, point cloud data can be explored to provide highly accurate measurements and three dimensional documentation of the actual scene.


Forensic Photography

Forensic photography is a key to any investigation, form scene documentation to the imaging of evidence. It also allows items of evidence that can not be exhibited in court, to be clearly presented. Using photography to exhibit items allows greater versatility through zooming, highlighting and enhancing relevant areas.

Time Line Mapping

CIn every case its important to clearly understand the sequence of events, the time lapse between the events and how each event interconnects. Time line mapping provides a clear chronological explanation of even the most complex sequences of events and interrelationships.

Interactive Mapping

Interactive mapping is an invaluable tool for clearly demonstrating the route a victim, suspect or an object took. It is extremely powerful for displaying interconnected data such a telephony and cell site data and how events are connected through proximity. The interactive nature of the mapping allows annotation and overlay of various types of information.

3D Modelling

The use of EPE’s have been proven to increase jurors retention and understanding and this can be increased even further through the use of 3D physical models. By harnessing 3D printing technologies it is possible to produce 3D models of almost anything imaginable, from buildings to body parts, each providing better understanding for a jury.

Aerial Imagery

Being able to view a scene or landscape from above adds valuable context during a trial, however it has previously relied on expensive methods involving aircraft or often out of date satellite photography. By using modern commercial available Unmanned Aerial Vehicles (UAV's / mini drones) matched with high quality camera, makes ariel imagery cost effective for any case.

3D Body & Injury Mapping

3D body and injury mapping provides a greater level understanding of mechanisms of injuries and causes of death than 2D photos can ever achieve. Multiple layers can be demonstrated; skin, muscles, circulatory systems and skeleton; ensuring complex pathology data is presented in an easy to understand way, whilst avoiding prejudice cased through viewing distressing autopsy photographs.
