311 P.3d 888
Or. Ct. App.2013Background
- Troopers stopped defendant’s car for an unlit license plate and overly tinted windows after observing an apparent rendezvous with another car and other suspicious behavior.
- During the stop troopers detected strong odors from the vehicle, observed a passenger acting nervously and suspected methamphetamine use, and learned of defendant’s prior drug-related charges.
- Officer McDowell summoned his drug-detection dog, Mauri; Mauri circled the vehicle on a leash and exhibited an "area" and then a "specific" alert at the driver-side door seam.
- Based on the dog’s alert, officers searched the car and found methamphetamine and marijuana; defendant moved to suppress the evidence as the fruit of an unreasonable warrantless search.
- At the suppression hearing the state introduced only McDowell’s testimony about Mauri’s training, certification (by Puget Sound Security), short certification history, and an asserted 100% field accuracy rate without specifying the number of alerts.
- The trial court denied the motion; on appeal the court of appeals held the state failed to prove Mauri’s alert was reliable enough to contribute to probable cause and reversed.
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Duncan) | Held |
|---|---|---|---|
| Preservation of dog-reliability claim | Suppression addendum was untimely; issue not preserved | Addendum raised dog-reliability; trial court accepted and considered it | Preserved — defendant properly raised the dog-reliability challenge at the hearing |
| Whether Mauri’s alert supplied probable cause to search | Mauri was trained, certified, and her alert plus other indicators furnished probable cause | State failed to show training/testing/certification details or meaningful field data; alert unreliably established | Denied: record did not establish sufficient reliability of Mauri’s alert; without it officers lacked probable cause, so suppression should have been granted |
Key Cases Cited
- State v. Foster, 350 Or. 161 (2011) (dog-alert may supply probable cause if dog-handler team’s training, testing, and performance are shown on the record)
- State v. Helzer, 350 Or. 153 (2011) (insufficient, vague training/testing evidence can render a dog’s alert unreliable)
- State v. Davis, 295 Or. 227 (1983) (warrantless searches are per se unreasonable unless an established exception applies)
- State v. Meharry, 342 Or. 173 (2006) (exigent-circumstances and automobile exceptions to warrant requirement explained)
- State v. Brown, 301 Or. 268 (1986) (automobile exception: need probable cause and vehicle mobility)
- Florida v. Harris, 568 U.S. 237 (2013) (field performance records have limited value; controlled certification testing is a better measure of a dog’s reliability)
