893 N.W.2d 536
S.D.2017Background
- On Sept. 25, 2015, Officer Wagner observed a white vehicle driving fast and followed it into a gas station; the driver, Matthew Hopkins, emerged from the restroom.
- Hopkins kept his hands in his pockets despite requests to remove them; the officer frisked him, handcuffed him briefly for officer safety, and smelled alcohol.
- While handcuffed during a brief frisk and identity check, the officer asked why he was driving fast and whether he had been drinking; Hopkins admitted drinking.
- A preliminary breath test showed .138%; Hopkins was arrested, refused consent to a blood draw, a warrant was obtained, and blood showed .162%.
- Hopkins moved to suppress his statements and physical evidence as obtained in violation of Miranda and as fruit of the poisonous tree; the trial court denied suppression and convicted him of driving with .08%+ (and he pleaded guilty to a prior-offense allegation).
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Hopkins) | Held |
|---|---|---|---|
| Whether the officer’s on-scene questioning was a custodial interrogation triggering Miranda. | The encounter was an investigative Terry stop, not custodial; the questions were routine and brief. | Handcuffing (and placement in patrol car) rendered the encounter custodial, so Miranda warnings were required. | The totality of circumstances did not establish Miranda custody; suppression denied. |
| Whether physical evidence should be suppressed as fruit of the poisonous tree. | Evidence is admissible because statements were voluntary and not obtained in Miranda custody. | Physical evidence derives from Miranda violations and should be suppressed. | Court did not reach this issue because it found no Miranda violation. |
