Slip Opinion
Tex. App.2014Background
- At ~4:00 a.m. on Oct. 26, 2008, Pearson was involved in a high‑speed collision that killed two teens; he was transported to a hospital and charged with two counts of intoxication manslaughter.
- DPS Trooper Aguilar investigated the scene (beer cans found; no skid marks; gouge marks, severe vehicle damage) and later went to the hospital around 10:00 a.m. to interview Pearson.
- At the hospital Pearson smelled strongly of alcohol, had bloodshot eyes, admitted drinking to officers/EMS, refused a voluntary blood draw, and was not under arrest when a nurse drew blood at Aguilar’s direction around 10:30 a.m. (≈6+ hours after the crash).
- DPS lab testing showed a BAC of ≈ .10 at 10:30 a.m.; the lab analyst (Zuniga) also gave a generalized retrograde extrapolation estimating a hypothetical BAC ≈ .26 at 4:00 a.m. based on assumptions.
- Pearson moved to suppress the blood evidence (warrantless draw/exigency) and challenged the retrograde extrapolation as unreliable; the trial court denied both motions, a jury convicted, and Pearson received concurrent 50‑year sentences.
Issues
| Issue | Plaintiff's Argument (Pearson) | Defendant's Argument (State) | Held |
|---|---|---|---|
| 1) Admissibility of warrantless blood draw (exigency) | Officer lacked exigent circumstances to justify warrantless blood draw; delay (≈6 hours) undermines exigency and officer created exigency. | Trooper Aguilar reasonably delayed due to scene duties, was sole officer, would have needed hours to obtain a warrant on a Sunday, and alcohol dissipates quickly so immediate draw was necessary. | Affirmed: trial court did not abuse discretion — totality of circumstances supported exigency and officer did not manufacture it. |
| 2) Admission of retrograde extrapolation expert testimony | Zuniga's extrapolation was unreliable under Mata (no individualized data; single test; long delay). | Even if extrapolation weak, it supplemented other admissible evidence and was disclosed as generalized/hypothetical. | Abuse of discretion to admit extrapolation under Mata, but error was harmless because the testimony was cumulative and other evidence was overwhelming. |
| 3) Sufficiency of evidence of intoxication | Without reliable retrograde extrapolation, evidence was insufficient (no contemporaneous breath/field test). | Multiple witnesses smelled alcohol, Pearson admitted drinking, beer cans found, refused blood test, and physical crash evidence supported impairment. | Affirmed: viewing evidence in the light most favorable to verdict, a rational juror could find intoxication beyond a reasonable doubt. |
Key Cases Cited
- Schmerber v. California, 384 U.S. 757 (warrantless blood draw permitted where exigent circumstances exist)
- Missouri v. McNeely, 569 U.S. 141 (exigency for blood draws determined case‑by‑case; metabolization alone not per se exigency)
- Jackson v. Virginia, 443 U.S. 307 (standard for sufficiency review — any rational trier could convict)
- Mata v. State, 46 S.W.3d 902 (Tex. Crim. App. 2001) (standards for reliability of retrograde extrapolation)
- Bagheri v. State, 119 S.W.3d 755 (Tex. Crim. App. 2003) (retrograde extrapolation error is non‑constitutional; harmless‑error analysis applies)
