State v. Dixon
2012 Minn. App. LEXIS 123
| Minn. Ct. App. | 2012Background
- Dixon was charged with first-degree burglary based on latent-print identifications using ACE-V.
- Dixon moved for Frye-Mack hearing to challenge admissibility of fingerprint evidence identifying Dixon as source.
- Bunkers collected latent prints; lab used ACE-V under SWGFAST procedures and facility accreditation.
- A full Frye-Mack hearing concluded ACE-V is generally accepted and reliable; district court admitted the evidence via stipulated facts trial.
- Expert testimony from Langenburg, Neumann supported reliability; Dixon offered contrary testimony challenging acceptance of ACE-V.
- District court allowed Bunkers to testify that identification was made to a reasonable scientific certainty.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Who is the relevant scientific community for Frye analysis? | Dixon argues latent-print examiners alone define community. | Dixon contends Fenney excludes broad forensic participants. | District court correctly defined as latent-print experts and researchers testing ACE-V. |
| Is ACE-V generally accepted in the relevant scientific community? | Dixon disputes broad acceptance of ACE-V. | Dixon argues lack of consensus and NAS critiques undermine acceptance. | State met Frye prong; ACE-V generally accepted. |
| Whether Mack reliability findings support the specific latent-print evidence here? | Dixon attacks reliability and documentation of Bunkers’s process. | Bunkers's method conformed to SOPs, verification, and lab standards. | District court did not abuse discretion; evidence reliable under Mack. |
| Whether Bunkers may testify that the opinion is to a reasonable scientific certainty? | Certainty phrase risks implying absolute certainty. | Courts allow such phrasing for qualified experts. | District court did not abuse discretion; testimony allowed. |
