— A Yakima Valley man was arrested Thursday afternoon when an Oregon state trooper stopped a car on U.S. Highway 97 near Klamath Falls, Ore., and discovered 13 pounds of marijuana in the trunk, authorities said.

The driver was cited on suspicion of illegal possession and distribution of a controlled substance and then released. A passenger — identified as 27-year-old Mario Serrano-Lopez of Wapato — was arrested and jailed on suspicion of the same charge.

A 27-year-old woman riding with them was released.

Oregon State Police said in a news release issued Friday afternoon that the marijuana is valued at $30,000.

Troopers are continuing to investigate.
