, stills, and other audio visual aids. Application of

in courtrooms today is becoming more popular. The first use of forensic animation was in ''Connors v. United States'', both sides used computer re-creations and animations in a case surrounding the crash of Delta Flight 191 on August 2, 1985. The crash resulted in the deaths of 137 people and extensive property damage. In the resulting lawsuit a method was required to explain complicated information and situations to the jury. As part of the plaintiff presentation, a 45-minute computer generated presentation was created to explain the intricacies of the evidence and thus began forensic animation. The first reported use of computer animation in a U.S. criminal trial was in the 1991 Marin County, CA homicide trial of James Mitchell (of the porno-businessman Mitchell Brothers) The prosecution used the animation to explain the complex details of the shooting incident to the jury. It showed the positions of James Mitchell, Artie Mitchell (the victim), the bullet impact points, and the path taken by bullets as they entered Artie's body. The animation was admitted, over objection by the defense, and the case resulted in a conviction. The use of the animation was upheld on appeal and the success of the forensic animation led to its use in many other trials. In India Prof. T D Dogra at AIIMS New Delhi in 2008 used animation to explain the court of law and investigating agencies first time in two important cases of firearm injuries, case of Murder and Terrorist encounter killings (
