525 S.W.3d 800
Tex. App.2017Background
- Early morning on Trinity River, game warden Patricia Vannoy, in a marked patrol boat, swept a flashlight toward Neale’s approaching boat; blue takedown lights were not activated. Neale later approached and Vannoy initiated a statutorily authorized vessel stop and boarded to perform a water-safety inspection.
- During the inspection, Vannoy smelled a strong odor of alcohol; Neale admitted drinking about five beers and showed unstable behavior (stumbling, putting life preserver on inside-out).
- Vannoy administered afloat and four seated standardized field sobriety tests (including HGN); she arrested Neale for boating while intoxicated.
- Neale consented to a blood draw; a technician drew blood at the hospital, and the specimen was later analyzed by DPS scientist Brian Nacu, who testified to a BAC of 0.169 and (via extrapolation) opined it was at least .19 at time of arrest.
- A jury convicted Neale of Class B misdemeanor BWI; Neale appealed, raising: (1) illegal stop/motion to suppress, (2) admission of HGN testimony, (3) admission of retrograde extrapolation testimony, and (4) admission of blood-test results. The State conceded issues 3 and 4, but the court independently reviewed and affirmed the conviction.
Issues
| Issue | State's Argument | Neale's Argument | Held |
|---|---|---|---|
| 1. Legality of initial stop/suppression | Vannoy’s flashlight sweep did not effect a seizure; encounter was consensual until she boarded under statutory authority to inspect vessels | Flashlight sweep was a show of authority that produced a seizure without reasonable suspicion; all subsequent evidence should be suppressed | Use of flashlight alone (100 yards away, no takedown lights, no other show of force) did not constitute a seizure; detention began when warden boarded to inspect; denial of suppression affirmed |
| 2. Admissibility of HGN testimony | HGN is valid scientific evidence; minor deviations from NHTSA procedure go to weight, not admissibility | Warden deviated from proper HGN protocol (timing, instructions, screening), rendering HGN inadmissible | HGN admissible; deviations were slight and affect weight, not admissibility; any error harmless given other evidence |
| 3. Retrograde extrapolation testimony | Conceded error by State, but testimony was brief, not emphasized, and cumulative given other strong evidence of intoxication | Nacu’s retrograde extrapolation improperly presented scientific certainty about BAC at time of operation | Court independently reviewed; although admission was error, under Bagheri factors the error was harmless (slight effect) and conviction stands |
| 4. Admission of blood-test results | Conceded error by State on foundation for lab methods, but Neale failed to preserve appellate complaint at trial | Laboratory testimony lacked proper foundational proof (compounded chemicals, machine theory) to admit blood results | Complaint not preserved (trial objections below did not mirror appellate grounds); appellate issue waived and admission upheld |
