An early morning Sunday traffic stop led to the discovery of nearly 4 pounds of methamphetamine and the arrest of a 36-year-old California man on drug charges, authorities said.

Oregon State Police troopers stopped a car driven by Erick Salvador Hernandez-Ruiz for a speeding violation at 1:23 a.m. near milepost 43 on Interstate 5, according to the OSP.

The trooper became suspicious of Hernandez-Ruiz, of Modesto, and gained consent to search the sedan, the OSP said.

The trooper discovered 3.8 pounds of methamphetamine with a street value of about $55,000 concealed in an undisclosed location within the rear of the vehicle, OSP spokesman Lt. Gregg Hastings said. Hastings declined to be more specific.

No drug-detection dog was used, Hastings said.

Hernandez-Ruiz was arrested without incident on possession and distribution of methamphetamine and lodged Sunday in the Jackson County Jail, where he was being held without bail pending a review of his immigration status.
