An eastern Idaho man remains jailed in Oregon after police found 40 pounds of marijuana in his car, the latest in a string of huge busts in the region that have snagged suspects from as far away as Florida and Arkansas.

John Clifford Scott, 29, of Ammon, was driving a rented 2013 Chevrolet Cruze with a Utah license plate eastbound Thursday on Highway 20, near milepost 18, about 15 miles east of Bend, when an Oregon State trooper stopped him for unspecified traffic violations about 11:14 a.m.

A drug dog led police to the marijuana, which they estimated to be worth $100,000, according to Oregon State Police.

Scott was booked into jail on charges of unlawful manufacture, possession and delivery of a controlled substance. His bond is $15,000.

Scott was arrested one day after three people from Utah, including a mother and son, were arrested on the same highway with 69 pounds of marijuana in their Chevrolet Trailblazer.

Colby Ray Tapp, 24, was driving a 1999 Toyota Camry with Tyson Peterson, 25, as a passenger when a trooper stopped them about 9:37 a.m. and the Trailblazer, which was driven by Tapp's mother, Sandra Tapp, 47, of Francis, Utah.

The vehicles were traveling together to Salt Lake City, where the men live, according to Oregon State Police. The stop occurred at milepost 158, about 25 miles east of Burns.

Two Boise men also were arrested in Oregon last week with three pounds of marijuana in their car on Highway 201 near Ontario.

Last month, a man from Jacksonville, Fla., was arrested after police found 106 pounds of marijuana in his car during a traffic stop on Interstate 84 in Payette County, Idaho, on Dec. 19.

On Dec. 4, two men from Arkansas and a man from Indiana were arrested with 64 pounds of marijuana in Canyon County during a traffic stop on I-84.

And on Nov. 20, a Fayetteville, Ark., man was arrested after Boise police found 28 pounds of marijuana in his motel room.
