Use of Demonstrative Evidence Helps Jurors
Charts, summaries and images can be used during a trial. The images help
the jury understand the case. The rules of evidence allow large amounts
of information be reduced to chart form and shown to the jury or admitted
as an exhibit.
Rule 1006 of the rules of evidence allows lawyers to create and use these
charts. Sometimes, these materials are called demonstrative evidence.
This kind of evidence can also be in the form of models, animations, and
other objects to help explain testimony.
Recently, a map showing the direction of travel of a cell phone based on
the pinging of towers was admitted into evidence. The South Carolina Court
of Appeals approved this at trial.
