Quick Summary
Michael Serge (defendant) was convicted of first-degree murder after shooting his wife. The Commonwealth (plaintiff) introduced a computer-generated animation (CGA) at trial to illustrate their theory of the crime. Serge challenged the admissibility of this evidence.
The Supreme Court of Pennsylvania reviewed whether the CGA could be admitted as demonstrative evidence. It concluded that CGAs are subject to traditional evidence rules and can be admitted if authenticated and if their probative value exceeds possible prejudicial effects.
Facts of the Case
Michael Serge (defendant) was convicted of first-degree murder for fatally shooting his wife. In the ensuing trial, the Commonwealth of Pennsylvania (plaintiff) sought to introduce a computer-generated animation (CGA) to demonstrate their theory of how the crime was committed.
Serge opposed the presentation of the CGA as evidence, arguing it was not properly authenticated, lacked foundational support, and would be prejudicial. The trial court allowed the CGA, with the condition that it be authenticated as a fair and accurate representation of expert testimony and not include inflammatory content.
The CGA depicted the positioning of Serge and his wife, the trajectory of the bullets, and how Serge allegedly shot his wife first in the lower back and then through the heart. The trial court issued cautionary instructions to the jury regarding the demonstrative nature of the CGA before it was shown and reiterated its purpose during jury instructions.

- The Pennsylvania Supreme Court granted review to address the novel issue concerning the admissibility of CGA as demonstrative evidence.
I.R.A.C. Format
Issue
Whether a computer-generated animation (CGA) is admissible as demonstrative evidence in a criminal trial.
Rule of Law
A CGA is admissible as demonstrative evidence if it is properly authenticated, relevant, and its probative value outweighs any potential for unfair prejudice, in accordance with Pa. R.E. 401, 402, 403, and 901.
Reasoning and Analysis
The court considered whether CGAs should be treated differently from traditional forms of demonstrative evidence such as photographs or diagrams. It concluded that they should not be differentiated and that CGAs should be subject to the same criteria for admissibility. The court highlighted that while technology has advanced, legal principles regarding demonstrative evidence remain applicable.
The CGA’s relevance was established as it assisted the jury in understanding expert testimony on forensic and physical evidence related to the crime scene. The court also emphasized that any potential prejudice was mitigated by comprehensive jury instructions clarifying the illustrative nature of the CGA.
Conclusion
The Pennsylvania Supreme Court affirmed the admission of CGA as demonstrative evidence in this case, concluding that it met all necessary criteria for admissibility and that its probative value was not substantially outweighed by unfair prejudice.
Concurring Opinions
Chief Justice Cappy concurred, emphasizing that pretrial procedures should be followed in future cases involving CGA and highlighted the economic disparities between the Commonwealth and an indigent defendant when considering prejudice. Justice Castille concurred in result but expressed reservations about the necessity and economic utility of CGA evidence. Justice Eakin concurred in result but noted that admissibility should not be influenced by the financial resources of parties.
Key Takeaways
- A computer-generated animation (CGA) can be admitted as demonstrative evidence if it meets established criteria of authentication, relevance, and balanced probative value against potential prejudice.
- Traditional rules of evidence apply to new forms of technology-enhanced demonstrative evidence such as CGAs.
- Jury instructions play a critical role in mitigating potential prejudice from demonstrative evidence like CGAs.
