Oregon State Police say they pulled over a pickup on Interstate 5 northbound near Eugene and found 40 pounds of marijuana concealed in a false bed. Two men were arrested, one from Vancouver.

After a police dog noticed a scent last week, troopers called in the Springfield Fire Department. Firefighters used heavy saws to cut into the metal and expose the hidden pot, said OSP Lt. Gregg Hastings.

Troopers estimate the marijuana’s street value at $100,000, about $2,500 per pound.

“That was a significant discovery, especially the steps that were taken to try and conceal it and prevent being found,” Hastings said.

It began about 11:30 p.m. Aug. 28, when a trooper working overtime on construction zone enforcement stopped the Chevrolet pickup for a traffic violation, according to an OSP bulletin.

The driver was Guadalupe J. Barron Magana, 54, from Lathrop, Calif., and the passenger was Victor M. Valladares, 43, of Vancouver, the bulletin said.
