Rule of Law:
A computer-generated animation (CGA) is admissible as demonstrative evidence if it is properly authenticated as a fair and accurate representation of the evidence it purports to portray, is relevant to a fact at issue, and its probative value is not outweighed by the danger of unfair prejudice.
Facts:
- On January 15, 2001, Michael Serge, a former Lieutenant of Detectives with the Scranton Police Department, shot his wife, Jennifer Serge, three times inside their home, resulting in her death.
- At trial, Michael Serge alleged that he had acted in self-defense after his wife attacked him with a knife.
- Serge also claimed that his extreme intoxication at the time of the shooting rendered him incapable of forming the specific intent to kill.
- The Commonwealth contended the killing was intentional and that Serge used his police experience to tamper with the crime scene to create a false self-defense scenario.
- Specifically, the Commonwealth alleged that after the shooting, Serge moved his wife’s body and strategically placed a knife near her on the floor.
Procedural Posture:
- The Commonwealth charged Michael Serge with first-degree murder in the Court of Common Pleas of Lackawanna County (trial court).
- Prior to trial, the Commonwealth filed a Motion in Limine seeking permission to present a CGA illustrating its theory of the case.
- Following a hearing, the trial court granted the Commonwealth's motion, conditioned on the establishment of proper evidentiary foundations at trial.
- A jury found Serge guilty of first-degree murder, and the trial court sentenced him to life imprisonment.
- Serge (as appellant) appealed to the Superior Court of Pennsylvania, an intermediate appellate court, which affirmed the judgment of sentence.
- The Supreme Court of Pennsylvania, the Commonwealth's highest court, granted Serge's (as appellant's) petition for allowance of appeal on the limited issue of the CGA's admissibility.

Issue:
Is a computer-generated animation (CGA) illustrating the prosecution's theory of a homicide admissible as demonstrative evidence in a criminal trial?
Opinions:
Majority - Justice Newman
Yes, a computer-generated animation (CGA) is admissible as demonstrative evidence if it satisfies traditional evidentiary requirements. A CGA should be treated like any other demonstrative exhibit and is admissible if it is properly authenticated, is relevant, and its probative value outweighs any potential for unfair prejudice. The court reasoned that a CGA is simply a modern technological tool, akin to a hand-drawn diagram, used to illustrate an expert's opinion. In this case, the CGA was properly authenticated by its creator and the experts whose opinions it depicted. It was relevant because it provided a clear and concise illustration of the Commonwealth’s complex theory of the crime, combining forensic and physical evidence. The court found it was not unfairly prejudicial because the animation was clinical, devoid of emotion, sound, or gore, and the trial court provided thorough cautionary instructions to the jury explaining that the CGA was merely an illustration of a theory, not a definitive recreation of events.
Concurring - Chief Justice Cappy
Yes, the CGA was admissible. While joining the majority, this opinion advocates for stricter procedural requirements. It argues that the prosecution should be required to file a pretrial motion in limine to admit a CGA in all future cases. It also emphasizes that when weighing prejudice, a trial court must consider the financial disparity between the parties and whether an indigent defendant should be given funds to procure a competing CGA. Finally, it states that limiting instructions, like those given here, should be mandatory in all cases involving CGAs.
Concurring - Justice Castille
Yes, admission was not an abuse of discretion in this specific case. However, this opinion expresses significant reservations about the general use of CGAs, warning that they are not inherently neutral and are subject to human manipulation and bias. It highlights the substantial cost of CGAs, which creates an imbalance when the defendant is indigent. The opinion suggests that where a defendant cannot afford to produce a competing animation or effectively challenge the prosecution's, the 'wisest course' for a trial court might be to exclude the CGA evidence entirely.
Concurring - Justice Eakin
Yes, the CGA was admissible, but the majority's discussion of finances and motions in limine is unnecessary and potentially dangerous dicta. Admissibility should be based on relevance, not the financial status of the parties; the remedy for an indigent defendant is to request funds from the court, not to exclude the other side's relevant evidence. The opinion argues that existing rules of evidence for demonstrative evidence are adequate to handle CGAs without creating special new rules for this specific technology.
Analysis:
This case establishes the legal standard for the admissibility of computer-generated animations (CGAs) in Pennsylvania, treating them as demonstrative evidence subject to traditional evidentiary rules. The decision signifies the judiciary's willingness to adapt existing legal frameworks to new technologies rather than creating entirely new tests. However, the concurring opinions reveal a significant underlying tension regarding the practical implications of expensive technology in the courtroom, particularly the potential for prejudice against indigent defendants who cannot afford to rebut such evidence, a debate that will likely influence future cases involving high-tech evidence.
