Facts
The Defendant was charged with multiple offenses, including kidnapping, criminal sexual penetration, aggravated battery, and extortion. The State relied on DNA evidence to link the Defendant to the crimes, asserting that the Defendant's DNA matched samples taken from the victim with an extremely high probability of accuracy. The Defendant pled no contest to the charges but reserved the right to appeal the admissibility of the DNA evidence (paras 1, 16-18).
Procedural History
- District Court, Bernalillo County: The trial court admitted the DNA evidence presented by the State. Following this ruling, the Defendant pled no contest to the charges while reserving the right to appeal the evidentiary ruling (para 1).
Parties' Submissions
- Defendant-Appellant: Argued that the DNA evidence should not have been admitted because the FBI's database and statistical methods used to calculate the probability of a DNA match lacked general acceptance in the scientific community. The Defendant presented expert testimony challenging the reliability and scientific acceptance of the FBI's methods (paras 20-23, 42).
- State-Appellee: Contended that the DNA evidence was reliable and generally accepted in the scientific community. The State presented expert testimony supporting the validity of the FBI's DNA analysis and statistical methods. It also argued that the appellate court lacked jurisdiction to review the admissibility of the evidence since a jury had not considered it (paras 2, 16-19).
Legal Issues
- Did the appellate court have jurisdiction to review the admissibility of the DNA evidence? (para 2)
- Was the DNA evidence, including the FBI's database and statistical methods, generally accepted in the scientific community and therefore admissible under the Frye standard? (paras 3-11)
Disposition
- The appellate court held that it had jurisdiction to review the admissibility of the DNA evidence (para 2).
- The court reversed the trial court's decision to admit the DNA evidence, finding that the FBI's database and statistical methods lacked general acceptance in the scientific community (paras 46-47).
Reasons
Per Chavez J. (Black and Flores JJ. concurring):
Jurisdiction: The court rejected the State's argument that it lacked jurisdiction to review the admissibility of the DNA evidence. It held that the Defendant's plea of no contest, with a reservation of the right to appeal the evidentiary ruling, allowed the court to consider the issue. The State had waived its ability to argue harmless error by entering into the plea agreement (para 2).
Admissibility of DNA Evidence: The court applied the Frye standard, which requires scientific evidence to be generally accepted in the relevant scientific community to be admissible. It emphasized that New Mexico law requires a "clear majority" of scientific acceptance, not mere absence of opposition (paras 3-11).
Expert Testimony: The court reviewed the testimony of experts presented by both parties. While the State's experts supported the reliability of the FBI's DNA analysis, the Defendant's experts raised significant concerns about the validity of the FBI's database and statistical methods. The defense experts testified that the FBI's approach was not generally accepted in the scientific community, particularly in the field of population genetics (paras 16-23, 42).
Judicial and Scientific Literature: The court examined rulings from other jurisdictions and scientific literature. It found that while DNA evidence is widely accepted, the specific methods used by the FBI, particularly its database and statistical calculations, were subject to significant criticism and lacked general acceptance. The court noted that other courts applying the Frye standard had similarly excluded FBI DNA evidence due to these concerns (paras 24-39).
Conclusion: The court concluded that the State failed to meet its burden of proving that the FBI's database and statistical methods were generally accepted in the scientific community. It reversed the trial court's decision to admit the DNA evidence and remanded the case for further proceedings (paras 40-47).
