Matt Oxner was hired by the South Dakota Highway Patrol in the fall of 1999. While on the South Dakota Highway Patrol, Trooper Oxner has seized more than 1,300 pounds of illegal drugs and narcotics and $715,040 in US currency. In 2003, Trooper Oxner received an award in Rapid City for his "Outstanding Achievement in Law Enforcement." Keya is a two year old yellow lab. (Info from SDHP website)
I have heard from four different people who have been busted by Matt Oxner. Their stories were strikingly similar to one another. Oxner's MO seems to be to stop everyone with west coast license plates. After talking to them, if he wants to search their car, he gets Keya out and walks her around the suspect vehicle. He pats a side window and Keya puts her front feet on the window. Oxner then mimics pawing with his hand, and Keya scrapes the window with her paw. Oxner calls that a 'hit' and searches the vehicle.
Occasionally he finds what he wants. Most of the time, I suspect, he finds nothing. The saddest part about this is that the So. Dak. Supreme Court has ruled that it makes no difference. The fact that drug dogs are wrong over half the time makes no difference in the validity of their actions as "articulable suspicion of criminal activity." Anything that a cop calls an "alert" by a dog justifies searching a vehicle.
