560 S.W.3d 29
Mo. Ct. App.2018Background
- Trooper Hillyard stopped a car reported driving carelessly; he observed driving anomalies, smelled alcohol, and the driver (Mack) staggered, had slurred speech, and bloodshot eyes.
- Mack initially gave a false name and could not produce a driver’s license; he refused preliminary breath testing.
- Field sobriety testing showed impairment (6/6 HGN clues, 2/2 vertical HGN clues, failed one-leg stand and walk-and-turn); Mack was arrested and handcuffed.
- While seated in the patrol car but before Miranda warnings, Mack told the trooper he had been drinking and there might be a beer can in the vehicle; the officer then searched the car and found an open, empty alcohol container.
- Trooper read Miranda and implied-consent warnings after the search; Mack refused a breath test and was charged with DWI (one count ultimately tried).
- Mack moved to suppress his custodial pre-Miranda statements; the trial court denied the motion, the statements were played for the jury, Mack was convicted, and he appealed arguing Miranda/Fifth Amendment error.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether pre-Miranda custodial statements admitting drinking and a beer in the car should have been suppressed | Mack: Statements were involuntary responses to custodial interrogation and protected by the Fifth Amendment; admission violated Miranda | State: Statements were voluntary, not responsive to specific interrogation, and admissible | Court: Even assuming error, admission was harmless beyond a reasonable doubt because the statements were cumulative to overwhelming other evidence of intoxication |
