Facts

The case arises from a vehicular collision on July 13, 2001, where the Defendant's truck swerved into the opposite lane, colliding with another vehicle and causing the death of a passenger. The Defendant, who denied drinking alcohol, was found to have a blood alcohol content (BAC) of 0.04 six hours after the accident. A nearly-empty whiskey bottle was discovered at the scene, which the Defendant admitted was his. The Defendant was charged with vehicular homicide under two alternative theories: driving under the influence or driving recklessly (paras 3-6).

Procedural History

• District Court, Curry County: The Defendant was convicted of vehicular homicide. The trial court admitted expert testimony on retrograde extrapolation to estimate the Defendant's BAC at the time of the accident and denied the Defendant's motion to dismiss for a violation of his right to a speedy trial (paras 1, 8, 34).

Parties' Submissions

• Defendant-Appellant: Argued that the trial court erred in admitting the State's expert testimony on retrograde extrapolation, claiming it was unreliable and failed to account for critical variables. The Defendant also contended that his constitutional right to a speedy trial was violated due to a 30-month delay between arrest and trial (paras 1, 2, 9, 34).
• Plaintiff-Appellee (State): Asserted that the expert testimony on retrograde extrapolation was admissible, as any deficiencies in the expert's conclusions went to the weight of the evidence, not its admissibility. The State also argued that the delay in trial was justified and did not violate the Defendant's right to a speedy trial (paras 1, 2, 9, 34).

Legal Issues

• Was the expert testimony on retrograde extrapolation admissible under Rule 11-702 NMRA?
• Did the 30-month delay between the Defendant's arrest and trial violate his constitutional right to a speedy trial?

Disposition

• The Court of Appeals affirmed the trial court's decision to admit the expert testimony on retrograde extrapolation and upheld the Defendant's conviction for vehicular homicide (paras 1, 33, 50-51).

Reasons

Per Fry J. (Alarid and Bustamante JJ. concurring in part and dissenting in part):

Admissibility of Expert Testimony:
The Court held that the Defendant's objections to the expert's retrograde extrapolation calculations went to the weight of the evidence, not its admissibility. The expert's methodology was deemed scientifically valid, and any deficiencies in its application were for the jury to evaluate. The Court emphasized that New Mexico law focuses on the reliability of the scientific technique itself, not the specific conclusions drawn by the expert (paras 9-33).

Speedy Trial:
The Court applied the four-factor test from Barker v. Wingo and found no violation of the Defendant's right to a speedy trial. While the 30-month delay was presumptively prejudicial, much of the delay was attributable to the Defendant's actions, including motions and continuances. The Defendant's late assertion of his right and the lack of undue prejudice further weighed against his claim (paras 34-50).

Bustamante J., dissenting in part:

Bustamante J. disagreed with the majority's analysis of the expert testimony. He argued that the State's expert's assumptions, particularly regarding the Defendant's post-absorptive state, were unsupported and rendered the retrograde extrapolation unreliable. He contended that the trial court should have excluded the testimony as it lacked sufficient trustworthiness, emphasizing the importance of proper application of scientific techniques (paras 53-58).
