POCATELLO — Two Montana men were arrested Thursday afternoon after police said a trooper found 5 pounds of methamphetamine in the suspects’ car on Interstate 15 north of Pocatello.

Joseph Willoughby, 54, and John R. Veum, 54, both of Billings, Montana, have each been charged with one count of felony possession of a controlled substance with intent to deliver.

The drug bust occurred at approximately 5 p.m. Thursday after an Idaho State Police trooper initiated a traffic stop on a 2006 Saab 9-3 Aero that was traveling northbound on Interstate 15 north of Pocatello.

The Idaho State Police said Willoughby was driving the vehicle and Veum was the passenger.

During the traffic stop, authorities said the trooper became aware that criminal activity was taking place, and a probable cause search revealed 5 pounds of methamphetamine in the vehicle.

Willoughby and Veum were then taken into custody and booked into the Bannock County Jail.

A preliminary hearing in the case has been scheduled for 10:30 a.m. on April 12 at the Bannock County Courthouse.
