EVANSTON (WNE) — A Wyoming Highway Patrol K-9 helped in the seizure of 1,349 M30 fentanyl pills and 3.89 pounds of methamphetamine Thursday evening at a gas station just outside Evanston.

According to a WHP press release, Wyoming Division of Criminal Investigation special agents spotted a suspicious individual — identified as Jeffery Spencer — at the station.

The WHP joined in the investigation, and the K-9 responded to the scent of drugs in the vehicle driven by Spencer.

Upon searching the vehicle, the trooper seized the drugs along with a pistol.  Spencer, who told police he is homeless, is a convicted felon and is therefore not allowed to possess firearms. He was arrested at the scene and booked into the Uinta County Jail.

The M30 pill identifier belongs to round blue oxycodone pills. The name comes from the presence of an M on one side and a 30 along the top of the other side.

Subtle differences exist between real tablets and those laced with fentanyl. Fake pills often have logos with fewer imperfections.

Counterfeit oxycodone pills that are teal and marked V48 and white pills marked A215 can also contain fentanyl.

DCI believes the drugs were on their way to market in Wyoming communities.

This seizure has been the first notable fentanyl arrest since the WHP K-9 teams received fentanyl certification two weeks ago.

WHP Lt. Matt Arnell said he cannot comment because it is an active investigation.
