## Facts

- Money collected for a school fundraiser repeatedly went missing from a bank pouch kept in a locked office at a high school.
- Police installed covert, motion-activated surveillance equipment in the office: a concealed wireless digital camera and a DVR, later supplemented with a desk lamp after an initial unusable recording due to low light.
- After $20 was reported missing, police retrieved DVR footage showing the night watchman entering the office, going to the desk, taking the bank pouch, and leaving.
- The footage, copied from the DVR to a VHS tape for trial, contained two segments separated by an approximately 30-second time gap; the detective attributed the gap to motion-sensor recording behavior or malfunction, not tampering.
- The trial court admitted the VHS tape as substantive evidence under the silent-witness theory and convicted the defendant of misdemeanor theft after a bench trial.
- The appellate court reversed, finding the foundation insufficient (including concerns about tampering probability, the lack of the original DVR medium, and reliance on hearsay materials for chain-of-custody details).
- The state supreme court granted review.

## Issues

1. Whether, under the silent-witness theory, the State laid a sufficient foundation to admit a VHS copy of DVR surveillance footage despite a time gap and without introducing the original DVR recording.

## Decision

- The court reversed the appellate court and reinstated the conviction.
- It held that the State established a sufficient foundation, under a totality-of-the-circumstances approach, to authenticate and admit the VHS recording as a reliable depiction of the events.
- It concluded the 30-second gap and use of a copy affected the weight of the evidence, not admissibility, absent concrete evidence of alteration.
- It ruled the trial court did not abuse its discretion in admitting the video evidence.

## Legal Principles

- Under the silent-witness theory, automated recordings may be admitted without an eyewitness to the events shown if evidence supports a finding that the recording accurately depicts what occurred.
- Authentication under the silent-witness theory is assessed by the totality of the circumstances; no rigid checklist of foundational elements is required in every case.
- Gaps, omissions, or minor irregularities in a recording generally go to weight rather than admissibility unless they raise a genuine question of tampering or misrepresentation.
- A duplicate recording may be admitted when properly authenticated and there is no genuine question regarding authenticity or fairness; production of the original medium is not categorically required.
- Evidentiary admissibility determinations are reviewed for abuse of discretion, with deference to the trial court’s assessment of foundation and reliability.

## Conclusion

The court held that a surveillance recording may be authenticated as a “silent witness” through practical proof of reliability—such as testimony about installation, testing, operation, retrieval, copying, and identification—evaluated under the totality of the circumstances; a brief gap and use of a copied format did not bar admission without evidence of tampering.
