State of Arizona v. Xavier Hipolito Estrella
286 P.3d 150
Ariz. Ct. App.2012Background
- Estrella’s employer’s van had a GPS device placed without a warrant by DEA agents in July 2009 to investigate drug transport.
- GPS data showed the van’s movements; agents conducted surveillance and located Estrella driving the van in Tucson.
- Estrella was stopped for speeding and window-tint violations; an outstanding warrant led to his arrest.
- A search of the van yielded bundles of marijuana; Estrella was indicted on transportation for sale and possession for sale/possession counts.
- Estrella moved to suppress evidence from the GPS placement and data as Fourth Amendment violation; the trial court denied the motion.
- The jury convicted Estrella on all counts, and he was sentenced as a repetitive offender; the appellate court vacated the lesser-included offenses later in the opinion.
Issues
| Issue | Plaintiff's Argument | Defendant's Argument | Held |
|---|---|---|---|
| Whether warrantless GPS placement/search violated the Fourth Amendment | Estrella argues the GPS placement was a trespass/search | State contends no cognizable privacy interest in movements on public roads; no search | No Fourth Amendment violation found on trespass theory; GPS use not a search under Katz analysis taken to capstone |
| Whether Estrella had standing or reasonable privacy expectation to challenge GPS tracking | Estrella had reasonable expectation of privacy in movements | Borrowed-vehicle use and public-road movements negate privacy expectation | Estrella had no reasonable expectation in the van’s movements; suppression denied on privacy grounds |
| Application of Knotts and Jones to GPS tracking duration | Knotts reasoning controls; no privacy in public movements | Jones requires considering modern tracking; potential privacy interests exist | Knotts applied; tracking duration not sufficient to constitute a search under this record |
| Lesser-included offenses of possession vs. transportation for sale | Counts 2 and 3 are lesser-included offenses of count 1 | Convictions for lesser-included offenses could be improper if duplicative | Counts 2 and 3 vacated; only count 1 remains validly convicted and sentenced |
